Automotive Industry:
　　Electrical insulation components:
　　Honeycomb ceramic carrier for automobile exhaust purification and diesel engine exhaust gas filter DPF(Diesel Particulate Filter)made of Cordierite material for diesel engine exhaust purification are prepared by mixing,extrusion molding,drying,sintering and other processing of various materials such as aluminum oxide and silicon micro powder.
　　Silicon micro powder has proper particle size distribution,which makes the yield of honeycomb ceramic products forming and sintering higher and the thermal stability of products excellent.
