Aluminum oxide abrasive media blasting rice cooker,cookware etc
In the market,aluminum oxide includes calcined aluminum oxide and fused aluminum oxide, and fused aluminum oxide includes white fused aluminum oxide ,brown fused aluminum oxide,pink fused aluminum oxide and so on.
All of the fused aluminum oxide 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 two main fused aluminum oxide which are mostly used for blasting rice cooker,cookware etc–white fused aluiminum oxide and brown fused aluminum oxide.
White fused aluminum oxide ,also called white corundum,white fused alumina 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 aluminum oxide,also called brown corundum ,brown fused alumina BFA 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℃
