SILICA PARTICLES, PROCESS FOR PRODUCTION OF SAME, AND RESIN COMPOSITION CONTAINING SAME |
摘要 |
The object of the present disclosure is to obtain silica particles having the sharp particle size distribution and low water-absorbing rate and being used suitably as a filler of a sealing resin composition, a method for producing it, and a resin composition containing the silica particles and a resin. Silica particle having a water-absorbing rate of less than 1.0% measured 500 hours after being kept at a temperature of 50° C. and at a humidity of 90%, and at a temperature of 85° C. and at a humidity of 85%, D90/D10 of 3 or less, a true specific gravity of 2.1 g/cm3 or more, and an average particle diameter of 10μm or less.
