КЕРАМИЧЕСКИЙ ПИГМЕНТ КОРИЧНЕВОГО ЦВЕТА

摘要

FIELD: ceramic pigment technology, in particular manufacturing of colored ceramic products. ^ SUBSTANCE: claimed pigment contains (mass %): Fe2O3 21.90-23.10; ZnO 33.04-38.56; SiO2 1.10-2.4; Al2O3 0.89-1.08; TiO2 9.30-11.01; CaO 0.99-1.14; MnO 1.04-1.20; MgO 0.40-0.62; K2O 0.24-0.36; FeO 22.70-27.00; Na2O 0.32-0.54; P2O5 0.21-0.41; V2O5 0.25-0.30. Titanomagnetite concentrate and zinc oxide are used as raw materials. Pigment composition of present invention makes it possible to reduce synthesis temperature up to 750-11000C and increase color purity up to 31.5-33.1 %. ^ EFFECT: pigment composition with increased color gamma and improved chemical durability in aggressive environment. ^ 2 tbl
