Insulating material with low thermal conductivity, formed of a compacted granular structure |
摘要 |
Insulating material, of compacted structure and of low thermal conductivity, is formed of silica-based primary particles; it is obtained by heat treatment of a compound of silane, of which the mean diameter is at most equal to 100 A; the apparent density rho a expressed in g/cc is between 6.10-3 and 2.3.10-3d, d being the mean diameter of the primary particles expressed in A; in addition, this apparent density is at most equal to two thirds of the density of the solid material.
