Mineral pigment comprising a solid solution of different spinel

摘要

P the invention relates to a mineral pigment comprising a solid solution of different spinel. / p & & p & the pigment contains a crystalline structure of a first spinel and metal oxides forming of the spinels, of at least one second spinel, the first 4 and these oxides being combined in the form of a solid solution comprising a spinel structure of cubic of the first spinel and containing, in the dissolved state, in said structure, the oxides of at least the second spinel, the first 4 and at least the second spinel being present in all proportions, forming a solid solution in single phase. / p & & p & application: painting and varnish industry, coloration of objects made of ceramic, porcelains, enamels, and the like. / p
