| titleOfInvention | Amorphous siliceous powder, process for production thereof, resin composition, and semiconductor encapsulation material |
| abstract | 34 OF THE DISCLOSUREA semiconductor encapsulation material which exhibits a low viscosity and further improved moldability in encapsulation even when highly loaded with an inorganic filler; an amorphous siliceous powder suitable for the preparation of a resin composition useful as the encapsulation material; and a process for the production of the amorphous siliceous powder. An amorphous siliceous powder having a content of Si and Al of 99.5mass% or above in terms of oxides, wherein the Al content in the particle size region of 15 gm to less than 70 µm is 100to 30000 ppm in terms of oxides; the Al content in the particle size region of 3 gm to less than 15 gm is 100 to 7000ppm in terms of oxides; and the Al content in the whole particle size region is 100 to 25000 ppm in terms of oxides. It is preferable that the (A)/(B) ratio of the Al content (A) in the particle size region of 15 gm to less than 70 gm to theAl content (B) in the particle size region of 3 gm to less than 15 gm be 1.0 to 20.(no suitable figure) |
