Abstract

In the present article there were studied compositions, dispersiveness of pigment materials, obtained in FeSO4 – CaO (CaCO3, KOH) – H2O – O2 system using mechanical activation, microwave and thermal treatment. It was determined dependence of physical and mechanical properties of colored silicate brick upon composition and properties of pigment materials, which define their conditions of obtaining. It was pointed out that filler pigment (a-Fe2O3 + CaSO4) colors brick into bright-red color, while pigment (a-Fe2O3) – in cherry-brown color. It has been shown that the presence of impurity in the form of a basic iron salt in the composition of iron-oxide pigment materials gives the silicate brick a burgundy or cherry tint. Increase of strength of ready-painted products with filler-pigment added amounts up to 10% compared with control composition, with iron-oxide pigment – up to 50% under their dosage amounting 3% of silicate mixture mass.
