KES series means ultrafine functionnal alumina and easy sintered alumina. The raw materials are
calcined alumiana for dintering and low soda and low soda aliumina. After millimg process. It is classified to three
grade aslike low soda, medium soda and normal soda by soda content.
They are widely used for alumina ceramics in the industry of electro-oeramics by the character is tics
of heat resistance, chemical stability, high strength, abrasion-resistance, electro-insulation and etc.
