FIELD: chemistry.SUBSTANCE: invention relates to ceramic particles. Sintered particle includes ceramic material, which contains aluminium, iron and silicon oxides, with silicon oxides, in terms of SiO, constituting not more than 30 weight percent of total weight of oxides; iron oxide, in terms of FeO, constituting from 15 to 35 weight percent of total weight of oxides. True density of ceramic material is higher than 3.5 g/cm.EFFECT: increased strength of products.20 cl, 1 tbl, 3 dwg |
