Aluminum oxide


Al2O3 is more commonly known by the generic term “ceramic”.

Available in both an 85% and 99.5% grade, the 85% grade contains almost 15% silica making it sensitive to any high pH fluids such as caustic.

The 85 and 99.5 grades of ceramic are not very good conductors of heat.

The ceramic grades called silicon carbide (SiC) and tungsten carbide (Tc) are much better choices.
