- Normal Soda Series KA Part
General soda-alumina product is a product that determined as alpha-alumina after calcining to high temperatures in the only long rotary kiln in Korea. General soda-alumina products control the characteristics of the alumina according to the plastic temperature to produce products with various particle sizes, size-distribution and specific-surface area. In particular, the company controls and manufactures the a-size of Alumina under thorough plastic process control. General soda-alumina products are produced by controlling the α-size to 1㎛ to 4㎛, and have characteristics with a specific-surface area of 3 to 6 (㎡/g). Its applications are highly durable and used in the Fine Ceramic and Fire Resistance industries, and used in abrasive materials and glass-hardened materials.
