Spherical particles of silica-containing compound oxide and method of production |
摘要 |
By using a halogen-free siloxane and an organometallic compound containing at least one metal other than silicon as feed stocks, and simultaneously atomizing and burning them in a flame, spherical particles of silica-containing compound oxide are prepared which are substantially halogen-free, consist of 0.5-99% by weight of metal oxides and the balance of silica, and have a particle size of 10 nm to 3 mum. The particles are useful as a filler in epoxy resin base semiconductor sealants, a refractive index modifier or the like.
