Advantages

   

   
 

    The series of products are refined by advanced formulation and strict process, the product size distribution is reasonable, the particle fluidity is good, the intergranular bond is loose, the grindability is good, and the sintering is easy. Its porcelain is compact, smooth surface, high mechanical strength, good electrical insulation, is the ideal raw material for manufacturing special ceramics.

Hot die casting, grouting molding series
    The series of products have large grain diameter, stable performance, good molding performance, small shrinkage of products, wide range of use, especially suitable for hot die casting, grouting molding series, can be used for a variety of high temperature resistant porcelain (spark plug, etc.), wear-resistant porcelain (mortar pump shaft plug pump lining, impeller, grinding medium ball, etc.), electronic substrate, electronic vacuum tube and other aspects.

Refractory series
    The product has stable crystal shape, can improve the refractories of the product, improve the mechanical properties, suitable for the production of amorphous refractories (various high aluminum castable), shaped refractories (corundum brick, etc.), furnace building materials, etc., to meet customers' requirements for higher temperature, excellent thermal shock stability and processing characteristics, and extend the service life of refractory materials.

Casting type series
    The product has uniform grain, good filling performance and pouring activity, can improve the sintering density of castables, high temperature bending resistance, compressive strength, and enhance the wear resistance, corrosion resistance, erosion resistance and other properties of castables. It can be used for low cement, ultra-low cement or no cement castable, shaped refractory materials and precision polishing.
Alumina ceramic granulation powder

    By scientific research ingredients, automatic grinding, pulping, spray drying. The particle size distribution is uniform, the fluidity is good, the strength is moderate; The fabricated body has high strength, excellent demoulding performance and low firing temperature. The surface of the product is smooth and the structure is dense. It can meet the process requirements of rapid dry pressing of precision ceramics, and can produce electronic ceramics and structural ceramic components
