KLS series is the crystallized α-alumina produced from aluminium hydroxide by the process of
calcination, removing soda in rotary kiln. With under 0.05% of soda content, 1~4㎕ of α-size, they
are usually used for Al₂O₃ 90~98% of alumina ceramic, spark plug, electric insulating material and
the raw material of high quality of ceramics.
By BET and α-size, 3 kinds of products are available.
