- Low Soda Series KA Part
Low Soda series is the crystallized α-alumina produced from aluminum hydroxide through the process of calcination, removing caustic soda in a rotary kiln. With under 0.05% of caustic content, 1~4㎛ of α-size, they are usually used for alumina ceramics, spark plugs, electric insulating material, specialty glass and the raw material for high quality ceramics. Three kinds of products are available according to BET and α-size.
