Abstract
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.sup.-3 and 2.3.10.sup.-3 d, 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. This material is applicable as a thermal insulator in the field involving low temperatures and high temperatures and in the building sector.
