Heading: Science for ceramic production

The process of phase formation in the system of oxides NiO - CuO - Fe 2 O 3 - Cr 2 O 3 has been studied. It was found that in the presence of a mineralizer, the process of structure formation leads to the formation of two spinel-like phases of nickel ferrite and copper chromite. In the absence of a mineralizer, a solid solution of nickel-copper ferrite-chromite is formed. At a heat treatment temperature of 900 ° C, the presence of the delaphosite phase CuCrO 2 was found in the samples.
