Abstract

Porous pumice grains are wetted to form cellular silicate of mainly closed-cell structure, using dilute orthosilicate and C-containing material such as molasses or the like; the intermediate product is heated with rapid rise of temp. of 400 degrees in reducing atmosphere to 950-1150 degrees C.
