Sol-Gel Processing of Ceramic Pigments, Part 3: Synthesis of Uvarovite

摘要

Ceramic pigment of the garnet type "Victoria green" was produced industrially using the classic procedure: high temperature synthesis, long reaction time and presence of mineralizer The object of this investigation was the synthesis of garnet by the sol-gel method. Due to the high ho-mogenity of the initial reaction mixture with nano size particles, this method provided a possibility of uvarovite synthesis at lower temperature. For garnet synthesis by the sol-gel and hydrothermal method, colloidal silica, ammonium chromate and calcium chloride were used as.
