Hafnium (Hf) is a tetravalent transition metal that is silvery gray in color, glossy, and chemically similar to zirconium. It is found in zirconium rocks. It is distinguished by its stability at room temperature, capacity for air-borne spontaneous combustion, and high-temperature hydrogen absorption.
The hafnium alloy’s huge cross-section and superior welding and processing characteristics make it the perfect neutron absorber. Additionally, it is corrosion resistant and high temperature resistant. When employed in relatively small amounts, hafnium enhances the creep ductility and rupture lifetime of nickel-based superalloys and high temperature alloys.
Hafnium oxide is utilized in semiconductor fabrication procedures to create electrodes, filaments, and integrated circuits with smaller feature sizes. Super alloys contain hafnium together with niobium, titanium, or tungsten.
The Global Hafnium Alloy Market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
The key hafnium consumer and anticipated market leader is the alloy manufacturing sector. The hafnium industry is anticipated to expand because of the metal’s great affinity for carbon, nitrogen, and oxygen, which allows it to produce alloys with iron, titanium, niobium, tantalum, and other metals. The metal also provides strengthening through second-phase particle dispersion.
Hafnium is used in environments with extremely high temperatures, pressures, and stresses due to its high melting point, which helps strengthen grain boundaries and improves both high-temperature creep and tensile strength. Small amounts of hafnium also help increase the adhesion of protective oxide scales and improve corrosion resistance.
More than a third of the world’s demand for hafnium and hafnium production come from the creation of superalloys.The Van Arkel technique, which provides the majority of Hf’s superalloy needs in the form of very pure crystal bars, is used to create hafnium.
Hafnium-bearing alloys boost engine performance while also lowering pollutants and taking into account the level of pollutants, thus the demand from turbines is also having an impact on the use of hafnium alloys.The market is primarily driven by the rising demand for superalloys for various aerospace sector applications.
This might be attributable to the ongoing technological advancements and advances in aircraft production processes. Additionally, the market is being stimulated by the quick product use in the manufacturing of gas turbines, nuclear reactors, pressurized water reactors, and semiconductors.
