Abstract:
The solid-phase synthesis of Cr-Ca-Sn-Si purple red pigment, the preparation of chrome tin pink stains are studied by using eggshell, which is used as the raw materials introducing the calcium carbonate. Through the experiment of formula is optimized, and by controlling the calcinations temperature and
mineralizer measures a series of Cr-Ca-SnSi purple red pigments are prepared. The results showed that Cr-Ca-Sn-Si purple red pigments are prepared by using eggshell.

Keywords: Eggshell; Cr-Ca-Sn-Si purple red pigments; solid-phase method.
