Керамические пигменты черно-коричневого ряда на основе шлака сталеплавильного производства

Abstract

The work was carried out synthesis and study ceramic pigments brown-black series in the system of martin slag – Сr₂O₃ – NiO – С₀О. The crystal phase structure of the products of roasting pigment blends and its relationship with the optical-color characteristics was set. Developed pigments provide high quality indicators of the glaze coatings, and a wide range of brown (λ = 608 – 670 nm, KDR = 5,0 – 7,9 % and purity of color 2 – 22 %) and intense black (KDR = 3,9 %) color.
