Abstract
Magnesium nitride is obtained by passing nitrogen through a mixture of a magnesium compound such as oxide and a carbonaceous reducing agent at a high temperature, which may be about 1500 DEG C., in an atmosphere free from moisture.ALSO:Magnesium is obtained by heating magnesium nitride to a temperature, for example about 1600 DEG C., sufficiently high to decompose it into magnesium and nitrogen, in the presence of a substance, which may be a calcium compound such as calcium carbide or silicide, which combines with the nitrogen and prevents its recombination with magnesium. Fluxes such as fluorides may be present. The magnesium may be distilled off at normal or reduced pressure in a current of inert gas, or alternatively in a large excess of hydrogen, and may be collected in vacuo or in an inert gas, or it may be combined directly with other metals such as aluminium or beryllium to form alloys. The magnesium nitride may be made by passing nitrogen through a heated mixture of a carbonaceous reducing agent and a magnesium compound such as magnesium oxide.
