Brief introduction of white sintered mullite 70mesh :

white sintered mullite 70mesh 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 white sintered mullite 70mesh : The chamotte, Calcined flint clay, Calcined kaolin, Sintered mullite,Bauxite,flint clay, aggregate, fused mullite

 The process of white sintered mullite 70mesh :

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 white sintered mullite 70mesh :  metallurgy, petroleum, chemical industry, building materials, machinery processing, military, etc of thermal technology equipment.

Applications of white sintered mullite 70mesh :

Supply white sintered mullite 70mesh . Mainly used in investment casting, Cast steel, cast copper, Vacuum casting, plaster filler v-process, casting coatings, casting mold shell, etc.
