Abstract
The invention concerns a method for calcium nitride synthesis which consists in spraying in form of droplets, by means of a sprayer, a molten zinc-calcium alloy into a reactor containing nitrogen at high temperature. The resulting calcium nitride is collected in a collector unit at the lower part of the reactor. The zinc contained in the droplets is evaporated and condensed on the cooled walls of the reactor and can be reused for preparing another alloy. The zinc-calcium alloy is obtained by electrolysis of calcium chloride in an electrolytic cell whereof the cathode is a solution containing molten zinc.
Claims13
Calcium nitride synthesis process according to which nitrogen is made to react with a calcium source in a reactor, process wherein the calcium source is a molten zinc-calcium alloy and the nitrogen is previously heated to a temperature greater than or equal to the melting temperature of the zinc-calcium alloy.
