Abstract
The paper deals with calcium nitride obtained by combustion synthesis of calcium metal pellets in nitrogen at a pressure of 3 to 7 MPa. The nitriding degree for calcium is about 99%. The obtained product composition is investigated by chemical and X-ray diffraction analyses. It is found that α‑ and β‑Ca3N2 phases are the primary in the product. Impurity phases include the Ca2N phase, calcium nitrate and nitrite, and others.
