Our company produce low soda and easy sintering alumina for the purpose of supplying our products to electronics & ceramic industry areas. We also produce specialized alumina and lithium products. Such as flaky alumina, roundish alumina and Lithium Carbonate. CIS is a company that specializes in supplying ceramic, semiconductor materials & LIB materials
Our products, low soda and easy sintering alumina are made from roasting aluminum hydroxide in tunnel kiln and rotary kiln at high temperature to control the alpha crystal size for various special products. After calcination, the intermediate has a very low soda content which is then subjected to grinding using a ball mill and other processes to obtain fine alumina powder having easy sintering properties. It has good moldability and sinterability and also excellent surface smoothness and wear resistance. The product is suitable for making high quality ceramic products which require high dimensional accuracy, especially as IC substrate, cutting tools, and Special crucibles.
This high purity alumina also applied to the LIB separator coating materials for stability reinforced separator. some of specialized powder is used to epoxy compound for MCCL(Metal Copper Clad Laminate) and automobile interior materials.
