1.1 Alumina Content le Crystal Phase Evolution
( Litene tsa Alumina Lining)
Alumina lining blocks are thick, crafted refractory ceramics mainly composed of aluminum oxide (Al two O SIX), with content typically varying from 50% to over 99%, directly influencing their efficiency in high-temperature applications.
The mechanical strength, khanyetso ea kutu, and refractoriness of these bricks enhance with higher alumina focus as a result of the advancement of a durable microstructure dominated by the thermodynamically secure α-alumina (taemane) stage.
During manufacturing, precursor products such as calcined bauxite, integrated alumina, or artificial alumina hydrate go through high-temperature shooting (1400 °C– 1700 °C), advertising stage transformation from transitional alumina kinds (c, d) to α-Al Two O THREE, which displays phenomenal solidity (9 on the Mohs range) and melting factor (2054 °C).
