Detailed Description

Green rare earth silicon carbide(carborundum) is produced basically in the same way of common green silicon carbide(GC) except the different requirements of raw materials,in which the rare elements,encluding rare earth elements were quantitatively added in. Green rare earth silicon carbide(RGC) is a new high-performanced green silicon carbide material. RGC has color and appearance similar to that of common green carborundum,but significantly higher microhardness and toughness,and good at cutting edge,self sharpening,corrosion resistance,high temperature stability,better in sintering, sintered strength. RGC is suitable for use as abrasive material and cutting material, silicon carbide refractory material,high temperature corrosion resistance material,silicon carbide ceramic material,silicon nitride bonded silicon carbide material,et al. Green rare earth silicon carbide abrasive has twice removal rate as high as that of common GC,and threefold durability as high as the that of GC.The abrasive tools made of RGC have doubled grinding efficiency and threefold durability than those of GC. Green rare earth silicon carbide abrasives is specially suitable to grind hard alloy and hard and brittle metal and non metal materials,e.g. high wear-resistant super-hard high speed steel，Tungsten, molybdenum，jewels,quartz,ceramic,sapphire,crystal silicon,et al. Rare earth green silicon carbide is used as the cutting edge material for multi-wire sawing to cut silicon chips(silicon chips processing),could replace common green silicon carbide,and get significantly high sawing efficiency,reduce the cost of sawing and the silicon wafers.
