What is the purpose of white fused alumina pickling?
The iron content in white fused alumina increases as the particles become smaller, but in order to ensure the quality of white fused alumina , the iron content should not be too much, so in order to remove iron, a small amount of oxalic acid will be added in the production process of white fused alumina micropowder. Neutralize iron ions and improve the purity of white fused alumina
