Ceramic industry: the honeycomb ceramic carrier for automobile exhaust purification and the automobile exhaust filter DPF (diesel particulate filter) made of cordierite material for diesel engine exhaust purification are prepared by mixing, extrusion, drying and sintering of alumina, molten silicon powder and other materials. Silicon micro powder has appropriate particle size distribution, which makes the forming and sintering yield of honeycomb ceramic products higher and the thermal stability of products higher.

Molten silicon powder can be used as raw material and glaze of high-grade ceramics, high silicon brick, ordinary silicon brick and silicon carbide for kiln.
