METHOD OF MANUFACTURING HIGHLY POROUS BODIES FROM INORGANIC MATERIAL WHICH MAY BE USED FOR PREPARING HYGROSCOPIC, INFLAMMABLE OR RADIOACTIVE ARTICLES

摘要

1. Process for the manufacture of porous articles made of an inorganic material, comprising the following stages : a) manufacturing beads of pore-forming material, coated with an organic binder and with the said inorganic material, b) comprising the coated beads cold to form the said article, and c) subjecting the article thus obtained to a heat treatment under vacuum, carried out at a sufficient temperature to remove the pore-forming material by volatilisation.
