Abstract

The process of nitride formation during combustion of iron silicon with the addition of zircon concentrate in nitrogen gas is investigated. It is determined that in the presence of zircon (5-70%) ferrosilicon burns in a surface regime, and the products of combustion are multiphase. For the optimal parameters of synthesis (nitrogen pressure 4-7 MPa and sample diameter 35-40 mm) the products of combustion are a composition consisting of a ceramic constituent (Si 3N 4-ZrO 2-Si 2N 2O) and iron (α-Fe). The method of acidic enrichment is used to obtain a composite ceramic powder with iron mass content 0.5%
