Product Description

 Alumina Ceramic Plates or liner is made of AL2O3 by dry pressing and calcined at 1700 °C with rare metal oxide (yttrium oxide, rare earth etc.) as flux.

Material Properties

Features

1.High hardness -- Rockwell hardness is HRA80-90, hardness second only to diamond.

2. High wear resistance -- Its theoretical wear resistance is equivalent to 260 times of manganese steel and 170 times of high chromium cast iron.

3. Lighter weight -- Only half weight of steel, smaller equipment load.

4. Corrosion resistance -- It is inorganic oxides with extremely stable molecular structure and no electrochemical corrosion, so it can resist erosion of acids,alkali, salt solutions and organic solvents.

5. Smooth surface -- Its roughness is only 1/6 that of steel pipes thus less flow resistance.
