- 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 and the raw material for high quality ceramics. Three kinds of products are available according to BET and α-size.
