[0022] In order to make it easy to understand the technical means, creative features, goals and effects achieved by the present invention, the present invention will be further explained in conjunction with specific embodiments below.
[0023] A method for preparing zirconium nitride. The method uses metal zirconium powder of 80-120 mesh with a content of 99%-99.5% as a raw material, and ammonia gas as a reaction medium. The preparation process steps are as follows:
[0024] ① Open the liquid ammonia storage tank valve, the liquid ammonia enters the ammonia vaporizer, activate the heating water valve, the ammonia gas enters the continuous reactor through the automatic control valve, the control plate flowmeter, and the ammonia automatic alarm cut-off device, and the exhaust gas is opened at the same time Valve and pass the reacted waste gas into the incinerator for incineration;
[0025] ② Start the rotary switch of the reactor and start the heating zone at the same time, so that the...
