2,RC Cristobalite silica powder is natural quartz by temperature control(600-477 degrees C)is calcined into the quartz,the quality grading,grinding,purification,powder grading become cristobalite silica powder,the crystal phase to tetragonal,with quartz consistently excellent electrical properties,and the whiteness,brightness high,density of small,relatively low hardness of quartz crystal,refractive index is very close to most of the resin properties,so the high-grade coating,wood coating,adhesives,rubber and plastic area have excellent performance,especially as applied to fill the grain weight of rubber and plastic is filled,in massive cost reduction at the same time minimum to reduce the level of transparency and other properties of system;used in wood coating and adhesive system on the final product transparency also had an outstanding performance;the quartz holding rate is high,hot drum coefficient of 54*10K
