Alumina Ceramics:
Alumina ceramic pigments are inorganic salts, that is, metal compounds. The formation of its color is mainly due to its composition containing colorable metal elements, and it will eventually develop color after being grilled for hundreds or thousands of degrees. Due to the limited number of metallic elements that can be colored after high temperature, the types of ceramic pigments are also limited, and their hair color cannot be compared with painting pigments and organic printing pigments. In color matching, the principle of blending is the same as that of organic printing pigments, but it is different.
Ceramic pigments are divided into high temperature and low temperature pigments according to the conditions of use. High temperature pigments refer to stable color development when used at temperatures ranging from 1000 to 1500 ° C. They are mostly used for glazes and greens; low temperature pigments are used at temperatures ranging from 700 to 700. At 850 ° C, its color is stable, and it is used for glaze. It is mostly used for screen printing decals and art porcelain painting. Its color types are slightly more than high-temperature pigments. Pigments with different temperatures cannot be matched and tinted with each other, and pigments containing different metal elements are also limited in matching and tinting with each other.
properties: High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
