Production of ceramic pigments with diopside and anorthite structure using the gel method

The possibility of producing ceramic pigments with the diopside and anorthite structures by the sol-gel method using wollastonite is studied. It is established that the use of the gel method intensifies the synthesis of anorthite and diopside crystal structures by means of better homogenization of the batch components at the mixing stage. A positive factor is the effective formation of anorthite and diopside structures at relatively low temperatures (about 1100°C), as well as the mineralizing effect of the chromophores on the crystallization of these minerals.
