Alumina (Al2O3) and titania are combined to form the refractory compound aluminium titanate (Al2TiO5) (TiO2). The typical method for creating this polycrystalline ceramic material involves reacting alumina and titania powders to generate a solid solution with stoichiometric ratios.
Aluminium titanate is a suitable material for a variety of technological applications, including foundry parts (nozzles, crucibles, pouring spouts), converters for automobiles, and moulds for the glass industry.
These properties include good chemical resistance, low thermal conductivity, and high thermal shock resistance (due to a low thermal expansion coefficient).
The Global Magnesium Aluminum Titanate market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
Tailoring of magnesium aluminum titanate based ceramics from aluminum dross.By reaction sintering aluminium dross waste and rutile ore powders at a temperature of 1300 °C for 6 hours, magnesium aluminium titanate (MgAl8Ti6O25) “MAT” based ceramics were effectively created.
Different dross rutile combinations were created. XRD and FE-SEM were used to characterise the produced ceramic composites. Along with the linear thermal expansion, the physical and mechanical characteristics of MAT-based ceramics were also examined.
The solid solutions of the compositions Mg0.3Al1.4Ti1.3O5 and MgAl8Ti6O25 were first produced in the specimen containing 10% rutile, according to XRD measurements (R).
After that, their quantity increased by a further 60% when rutile was added. The specimen containing 20% rutile had the best results for the densification parameters.
The samples that were produced exhibit thermal stability even at elevated temperatures. Over a temperature range of RT-1200 °C, no breakdown was seen.
Furthermore, the obtained samples’ TECs are lower than those of AT ceramics. As a result, it is possible to think of the solid state sintering of rutile ore and aluminium dross waste as a promising method for creating new advanced ceramic materials based on MAT.
Additionally, using this waste has two inherent effects. Reusing this trash will benefit the environment first, and production costs second.
