Brief summary the similarities and difference of low sodium white fused alumina and normal white fused alumina
First,we list the similarities of low sodium white fused alumina and normal white fused alumina
1.Raw material:both are industrial aluminum oxide
2.Appearance is white powder
3.Production processing is almost the same:smelting,crushing,grinding,acid-washed,overflow classification,testing,packing etc
4,Production standard is the same,both according FEPA or JIS.
Secondly,we mainly talk about the differences of the low-sodium white fused alumina and nornal white fused alumina
1,Raw material:Normal white fused alumina use the common industrial aluminum oxide,but low sodium white fused alumina is strict,must be low sodilum aluminum oxide.
2.Color,although they both white,but if compare carefully,we can see that low sodium white fused alumina is a little dark,not white as as normal white fused alumina.
3.Physical properties:Low sodium white fused alumina,smelted longer time,then it has higher purity,higher hardness,bulk density and volume density.
4.Chemical compostion:the details is as follows:
| Al2O3 | Na2O | SiO2 | Fe2O3 | |
| Low sodium white fused alumina | ≥99.7% | 0.01-0.09% | ≤0.1% | ≤0.1% |
| Normal white fused alumina | ≥99.3% | 0.20-0.40% | ≤0.2% | ≤0.2% |
5.Applications:Except the applications of normal white fused alumina,low sodium white fused alumina also can used as high grade refractory,high grade ceramic grinding wheel,anti-sticking sand in electric field etc.The grinding efficicency will be increased if matchs with SG abrasives.
6.The cost: The cost of low sodium white fused alumina is higher much then normal white fused alumina.
