| titleOfInvention | Amorphous siliceous powder, process for production of the same, and use thereof |
| abstract | Provided are a resin composition, particularly a semiconductor encapsulation material, which exhibits a low viscosity in encapsulation even when highly loaded with an inorganic filler and which is further improved in moldability; and an amorphous siliceous powder suitable for the preparation of the resin composition; and a process for the production of the amorphous siliceous powder. The amorphous siliceous powder has an L/B ratio of 0.8 or below (wherein L is quantity of desorbed pyridine as observed in subjecting an amorphous siliceous powder containing pyridine adsorbed thereon to heating at 450 DEG C to less than 550 DEG C; and B is quantity of desorbed pyridine as observed in subjecting the same to heating at 150 DEG C to less than 250 DEG C). It is preferable that the ratio of the quantity (B) of desorbed pyridine as observed in heating at 150 DEG C to less than 250 DEG C to the total quantity (A) of desorbed pyridine as observed in heating at 150 DEG C to less than 550 DEG C, (B/A)100%, be 20% or above. Further, it is preferable that the amorphous siliceous powder have a specific surface area of 0.5 to 45m2/g, a mean particle diameter of 0.1 to 60[mu]m, and an average sphericity of 0.80 or above. |
