fused alumina abrasive media blasting rice cooker,cookware etc
In the market,fused alumina usually includes white fused alumina,brown fused alumina,pink fused alumina,zirconia fused alumina,semi-friable fused alumina etc.
All of them have the common charactoristics such as high hardness which make them were-resistance,of course they also have a little difference .
Today just talk about the fused alumina which are mostly used for blasting rice cooker,cookware etc–white fused aluimina and brown fused alumina.
White fused alumina ,also called white corundum or white aluminum oxide,it is made from high quality of aluminum oxide,the datasheet is as follows:
AVERAGE CHEMICAL COMPOSITION(TYPICAL)
Al2O3 ≥99.5%
Na2O ≤0.30%
Fe2O3 ≤0.06%
PHYSICAL PROPERTIES(TYPICAL)
Specific Gravity ≥3.90g/cm3
Mohs Hardness 9.0
Bulk Density 1.75-1.95g/cm3
Melting Point 2250℃
Brown fused alumina,also called brown corundum and brown aluminum oxide,is made from bauxite,whose specification is as below:
AVERAGE CHEMICAL COMPOSITION(TYPICAL)
Al2O3 ≥95.0%
SiO2 ≤1.6%
Fe2O3 ≤0.35%
TiO2 1.7-3.4%
PHYSICAL PROPERTIES(TYPICAL)
Specific Gravity ≥3.90g/cm3
Mohs Hardness 9.0
Bulk Density 1.53-1.99g/cm3
Melting Point 2250℃
