High purity ultra-fine silica powder is specially processed by high purity quartz, its melting point is 1713 degree, with no cleavage and only conchoidal fracture. It has excellent chemical stability and high insulation compression resistance, and the breakdown voltage is 32-34KV/mm, with low coefficient of thermal expansion.
These excellent properties bring a broad prospect for it to apply in electronic information industry, electric power industry, coating industry, light industry, and so on. High purity ultra-fine silica powder is the preference filler in integrated circuit (IC), microproducts and mold compound, and it is also the main filler in dry type encapsulating material for electricity transmission substation equipment. Using ultra-fine silica powder as filler in the mold compound and encapsulating material can make the packaged products have prominent features such as good resistance to temperature changes, small deformation, high insulation compression resistance, etc.
