Spherical fused silica and its use in fillers and resin compositions Abstract of the Disclosure Spherical fused silica with an average particle diameter within the range of 10 to 50 µm and having a particle size distribution of 1 to 100 µm in diameter is a useful filler for resin compositions having improved mechanical and electrical properties as well as good flow- ability and low viscosity. The spherical fused silica is preferably treated on its surface with a silane coupling agent. Resin composi- tions containing said spherical fused silica as the major filler are particularly useful as casting materials.
