What is Alumina Ceramics?

Wear-resistant ceramics are special corundum ceramics made of AL2O3 as the main raw material, rare metal oxides as the flux, and calcined at a high temperature of 1700 Baidu. As a new type of workpiece material, industrial ceramics have high-temperature resistance, high wear resistance, good toughness, high-temperature insulation, impact resistance, corrosion resistance, beating resistance, good welding performance, etc.

Features of wear-resistant ceramic lining: It has the characteristics of wear resistance, impact resistance, corrosion resistance, high-temperature resistance, and convenient construction. , ore concentrate, tailings, cement, etc.) is an ideal material for surface wear of conveying equipment. It is very safe to use in high-temperature corrosion, high-temperature wear, or high-temperature corrosion lining occasions, and its service life is longer than that of cast stone, wear-resistant alloy cast steel, steel Plastic, steel rubber, and other materials are ten to twenty times higher.

There are many forming methods of alumina ceramics, but the main ones are grouting, hot die casting, film rolling, dry pressing, isostatic pressing, casting, injection and gel injection molding, etc. Different forming methods correspond to different processes.

Different molding methods use different molds. Gypsum molds are used for grouting, metal molds are used for hot die casting and dry pressing, and rubber molds are mainly used for isostatic pressing. The above-mentioned various molding methods have different molding principles and processes, so their characteristics are also different, and each has its advantages and disadvantages. The choice of ceramic molding method should be comprehensively determined according to the performance requirements, shape, size, output, and economic benefits of the product. The grouting adopts an inexpensive gypsum mold, with simple equipment and low cost, and is suitable for the manufacture of complex-shaped ceramic parts and large-sized ceramic products.
