1.1 Alumina Content ug Crystal Phase Evolution
( Alumina Lining Brick)
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, pagbatok sa corrosion, 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 (diamond) 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).
The resulting polycrystalline structure contains interlocking corundum grains embedded in a siliceous or aluminosilicate glassy matrix, the make-up and quantity of which are thoroughly regulated to balance thermal shock resistance and chemical toughness.
Small ingredients such as silica (SiO ₂), titania (TiO ₂), or zirconia (ZrO ₂) may be introduced to change sintering habits, boost densification, or enhance resistance to certain slags and fluxes.
1.2 Microstructure, Porosity, and Mechanical Integrity
The efficiency of alumina lining blocks is seriously dependent on their microstructure, especially grain size distribution, pore morphology, and bonding phase attributes.
Optimum bricks display great, consistently distributed pores (closed porosity chosen) and very little open porosity (
