Abstract: Black ceramic pigments are currently widely used in the field of ceramic decoration. The traditional processes to produce black ceramic pigments require the addition of cobalt oxide, but the high price of cobalt oxide limits the development of black ceramic pigments. Therefore, the development of cobalt-free black ceramic pigments has become one of the hot spots in the research field of ceramic pigments and the spinel-type cobalt-free black ceramic pigments are favored by many researchers for their excellent high-temperature resistance, atmospheric adaptability and chemical stability. Based on the research progress of spinel-type cobalt-free black ceramic pigments, coloration mechanism, raw material types and preparation technologies of the above ceramic pigments were described and analyzed detailedly in this paper. At present, the raw materials for preparing the spinel-type cobalt-free black ceramic pigments can be mainly divided into chemical raw materials, mineral raw materials and industrial solid wastes. The preparation technologies mainly include the traditional high-temperature solid-state method, the microwave roasting method, the chemical precipitation method, the sol-gel method, the microemulsion method, the solution combustion method, etc. The coloring properties of prepared pigments are mainly affected by the mole ratio among transition metal elements in raw materials, the roasting temperature and the holding time. In comparison, microwave roasting of industrial solid wastes to prepare the above ceramic pigments has a good application prospect, but the formation and evolution mechanism of spinel in the preparation process and the influence of impurity components introduced by industrial solid wastes on the properties of pigments still need to be further studied.

Key words: black ceramic pigment, spinel, coloring mechanism, transition metal element, chromite, industrial solid waste
