CaO-SnO2-SiO2(Cr2O3) - Names and Identifiers
CaO-SnO2-SiO2(Cr2O3) - Physico-chemical Properties
| Molecular Formula | CaO-SnO2-SiO2(Cr2O3)
|
| Physical and Chemical Properties | Light red fine powder, aragonite-type pigment, belongs to monoclinic system. Its main body is tin Stone (CaO-SnO2-SiO2), and the chromium ion is dispersed in the tin stone crystal lattice and is red. Alkali metal oxides and reducing atmospheres have an adverse effect on the pink hue exhibited by the chrome-tin red in the glaze. The presence of gray tin (CaO-SnO2) in the main component is beneficial to improve the temperature resistance and the adaptability to the original atmosphere of the pigment. |
