Brief introduction of chamotte sand/flour for precision casting :

Mullite powder used in lost wax can be divided into shaped refractory products(Such as: Refractory brick ,Fire clay brick,High alumina brick, Heat insulation brick,Ceramic fiber products ect) and unshaped refractory materials(Such as:Refractory castable, Plastic refractory, High temperature refractory mortar ect), Widely used in metallurgy, petroleum, chemical industry, Cement, Glass, Casting,carbon,building materials, machinery processing, military, etc.

Refractory raw material of chamotte sand/flour for precision casting : The chamotte, Calcined flint clay, Calcined kaolin, Sintered mullite,Bauxite,flint clay, aggregate, fused mullite

process of mullite powder for chamotte sand/flour for precision casting :

Made from the natural high quality bauxite, our product is through multi-level homogenozaotpm and then calcined at about 1750 degree. it possesses many good characteristics such as high bulk density, stable quality, good thermal shock resistance, small index of high temperature creep and good resistance to cheamical corrosion, it is an ideal raw aterial for the following refractory products like a variety of shaped and unshaped refractories, advance ceramic asanitary ware body, precision casting models and so on.

Application of chamotte sand/flour for precision casting : metallurgy, petroleum, chemical industry, building materials, machinery processing, military, etc of thermal technology equipment.
