CHARGE FOR CERAMIC BLUE PIGMENT MAKING Russian patent published in 2002 - IPC

FIELD: ceramic industry. SUBSTANCE: invention relates to a technology of producing ceramic pigments and decorating porcelain-faience and majolica articles. Pigment has Al₂O₃ and TiO₂ as a calcinated product of neutralization of Ziegler-Nut's catalytic complex of the following composition, wt.%: Al₂O₃, 40-60; TiO₂, 40-60; and it comprises additionally CoO and B₂O₃ in the following ratio of components, wt.%: product of neutralization of Zigler-Nat catalytic complex, 78-93; CoO, 5-20; B₂O₃, 2. Pigment exhibits the enhanced acid resistance and alkali resistance, stability in glaze melts, not high temperature of synthesis. The use of industrial waste instead the conventional expensive raw makes the production of the proposed pigment as the more economy. EFFECT: valuable properties of pigment, decreased cost. 2 tbl, 1 ex
