Tungsten Carbide is a hard, brittle metal alloy that is composed of equal parts of tungsten and carbon atoms. It is often used as a cutting tool in machining and manufacturing processes due to its extreme hardness and abrasion resistance.
Its high melting point and low thermal expansion makes it ideal for high temperature applications, such as drilling and mining. Tungsten Carbide is also used in wear-resistant coatings, electronics, and aerospace components.
Tungsten Carbide is made by sintering a mixture of tungsten and carbon at temperatures up to 3000°C. This process results in a material with a hardness that is between 6 and 8 on the Mohs’ scale, making it one of the hardest materials known to man.
Its strength and durability make it an ideal choice for cutting tools, as it can withstand high temperatures and wear and tear better than other materials like steel or aluminum.
Tungsten Carbide also has excellent corrosion resistance, making it suitable for use in harsh or corrosive environments.
In addition, its low thermal expansion makes it suitable for use in electronics and aerospace components, as it will not expand or contract when exposed to extreme temperatures.
Tungsten Carbide is used in a variety of applications, from cutting tools and wear-resistant coatings to electronics and aerospace components. Its high strength and durability make it an ideal choice for many industrial and engineering applications.

Feasibility of nanomaterial tungsten carbide as lead-free nanomaterial-based radiation shielding.Radiation shielding is an efficient radiation protection strategy that absorbs intense ionising radiation to safeguard medical patients and staff.
Specific radiation shielding materials are more suited for some types of radiation than others, as indicated by the interaction of specific particles with the elementary characteristics of the shielding material.
When it comes to blocking or reducing radiation intensity, high-density materials outperform low-density materials.
Low-density materials, on the other hand, can account for the increased thickness difference, which is as significant as density in shielding applications.
The process of attenuating or absorbing harmful radiation using a variety of shielding materials, such as concrete, polymer composites, and heavy metals like lead and lead oxide/tungsten/tin composites.
The effectiveness of the material’s shielding depends on the radiation type present and the range of radiation-related energy.
Due to its high atomic number, density, low cost, and efficiency as a radiation shielding material, conventional lead has historically been the most often used shielding material in medical contexts. Gamma rays and X-rays can be mitigated by using lead.
The atomic number describes how many protons are present in an atom. In order to prevent photons from attempting to get through the barrier, the standard lead atom has a relatively high number of protons and a correspondingly high number of electrons.
When two electrons collide, energy is exchanged between them in the form of photons. When x-rays and gamma-rays reflect off of lead, a particular kind of boson called a photon is created.
Lead is a fantastic material for scattering these kinds of rays because of its high density and abundance of electrons.
Thick shielding barriers can improve the level of protection. Lead shielding, however, lacks longevity, chemical stability, and mechanical strength.
Lead may cause a thick oxide layer to form in the atmosphere, improving corrosion resistance. However, because neutrons are uncharged and easily pass through dense materials, lead is ineffective at blocking neutron radiation.
As a result, lead absorbs very little neutron radiation and degrades in specific ways when exposed to radiation. Medical staff are protected against ionising radiation with aprons and other lead-containing clothing.
However, regular use and maybe negligent handling of protective clothing often led to structural breakdown of a particular leaded rubber material, which reduced radiation shielding effectiveness.
Lead usage has raised concerns about safety and long-term health risks for medical personnel. Due to its extreme toxicity and prohibitively high cost of recycling, lead must be completely eliminated from clinical workspaces, along with the development of alternative lead-free products.
On the other hand, lead concrete needs a tremendous thickness and, as a result, a lot of room in order for the material to be more effective in radiation shielding. Lead concrete is also limited in various applications due to its weight, size, and toxicity.
As a result, the addition of nanomaterial polymers helps to increase the shielding material’s chemical stability. Additionally, lead-based radiation shielding equipment is cumbersome and heavy, making it unusable for the majority of applications. Traditional lead is extremely hazardous, endangering both patients’ and doctors’ health.
The need for novel radiation shielding materials that may be tailored to particular purposes has been increasing. In the last few decades, numerous studies have concentrated on nano and micro composite materials to absorb or attenuate high-energy radiation.
The capacity of nanoparticles to absorb photons is improved by the high area-to-volume ratio.Evidence points to the possibility of creating radiation shields that effectively attenuate radiation using nanoparticles dispersed in a polymer matrix.
Gamma radiation transmission through the selected thickness of the shielding material or the thickness of the shielding material required to achieve the specified attenuation level may be estimated using the material’s attenuation and density,where I represents the intensity after shielding and Io represents the incident intensity.
The mass absorption coefficient is, where is the density of the shielding material and t is its thickness. To satisfy the shielding requirements, the optimal shielding form for a given application may be selected based on criteria such as cost, weight, chemical and physical toughness of the materials, and attenuation properties.
There is a lot of interest in creating shielding materials that are safe for the human body and lighter than traditional lead to replace it.
One of the materials is a tungsten carbide (WC)-based substance that, when compared to lead, has a high atomic number and excellent shielding properties.
Tungsten carbide has the potential to be used effectively in a variety of applications, notably those involving radiation shielding. It is a non-toxic, lead-free substance with a greater density and atomic number than lead. As a result, tungsten carbide offers superior shielding capabilities over lead.
Additionally, tungsten carbide has been used in the creation of thin radiation shielding coatings as a lead substitute material.
It may be fabricated into a film using a variety of fabrication procedures that are suitable for a wide range of substrates and has high radiation shielding capabilities.
When tungsten carbide nanopowder is adsorbed on a film at high densities, the size and manner of powder particle dispersion must be taken into account. When the shielding material is fully occupied, the radiation shield’s density rises. On the other hand, it works well to prevent low-dose radiation.
The exceptional hardness and wear resistance of tungsten carbide nanoparticles in hard metals are further advantages. Cobalt is also added to tungsten carbide to increase its strength and hardness.
Researchers found that tungsten carbide nanoparticles were not immediately harmful to human and animal cells in culture. However, cytotoxicity was visible in all of the cell cultures tested when the tungsten carbide was doped with other metals.
This mixture’s potentially harmful effects highlight how crucial it is to verify tungsten carbide blends before they are applied broadly.
Over lead and concrete, thin film tungsten-based materials offer a number of benefits, including transparency, additive, light weight, ease of production, and, most significantly, no harmful effects on people.
Consequently, one possible study area is the production of tungsten carbide nanofilm as lead-free radiation shielding.
Nanomaterials are particularly important as radiation protection materials due to a number of reasons, including their lightweight construction, and have the ability to be produced in accordance with the exact specifications of a given industry.
However, a thorough analysis of the use of tungsten carbide nanofilm as a lead-free shielding material is still lacking in the literature.
A recent discovery that focuses on the morphological structure of tungsten carbide nanofilm, the development of tungsten carbide nanofilm as a radiation shielding material, a summary of thin film deposition, and various deposition procedures.
The principal difficulties and future prospects for structural analysis that will support the most effective design and analysis of tungsten carbide nanofilm as radiation shielding material in nuclear medicine applications.
