Production feature:
Tabular alumina has good heat resistance and good bulk temperature thermal shock capabilities. The crystal staggered plate shape, to increasing the mechanical strength of the particles; interior structure full of closed pores, high bulk density, low apparent porosity and water absorption, to reducing the amount of fluid re-use productions; With good physical properties like: high refractoriness, excellent thermal shock resistance, low shrinkage and good thermal load strength etc. Meanwhile, high-purity avoiding damage to machines. Sicheng is your best choose as refractory material/ceramic material and insulating materials.
Black silicon carbide is produced from quartz sand and high quality anthracite/petroleum coke under high temperature in and electric resistance furnace. It looks black and has a microhardness of 2800-3300kg/mm2. Abrasive tools made of it, are fit to grind metals and non-metals materials of low tensile strength, for example, grey cast iron, brass, alumina, stone, leather and hard rubber etc. It can also be used for refractory purpose or in electronic industry.
Application:
â?¢ production of abrasive tools designed for the finishing of the materials that have low resistance to extension, i.e. to the finishing of cast iron,
â?¢ aluminum, bronze, zinc, and also for tough and friable materials such as sintered carbide and glass,
â?¢ production of abrasive papers and cloths,
â?¢ in loose-grain machining, e.g. in gravestone letterer's craft,
â?¢ production of incombustible materials, heating elements in
Ceramic Foundry sand is made from high quality bauxite, by re-fused and blown to ball type. With advantage of fine surface smooth finish and air permeability, it is a new type casting material for precision casting, coated sand and self hardening sand etc.
