Abstract
Chromium oxide densification, bonding, hardening and strengthening of bodies having interconnecting porosity therein by impregnation with a chromium compound convertible to chromium oxide on heating, heating the impregnated body to convert the compound to chromium oxide and repeating the impregnation and heating steps. The body may be of any material composed of an oxide, has an oxide constituent or will form a well adhering oxide on its surface.
