Abstract

Perfectionnements aux matières thermo-isolantes. Une telle matière peut être réalisée par un mélange intime d'aérogel microporeux de silice, de fibres de renforçage et éventuellement d'un agent opacifiant. Suivant l'invention l'on ajoute de l'alumine sous la forme d'alumine particulaire ou de fibres d'alumine constituant tout ou partie des fibres de renforçage. Le produit obtenu tend à moins s'agglomérer et en conséquence à moins se rétracter à haute temperature. Plaque de cuisinière électrique.Improvements in thermo-insulating materials. Such a material can be produced by an intimate mixture of microporous silica airgel, reinforcing fibers and optionally an opacifying agent. According to the invention, alumina is added in the form of particulate alumina or alumina fibers constituting all or part of the reinforcing fibers. The product obtained tends to agglomerate less and consequently to shrink less at high temperature. Electric stove top.
