Production method and application of lanthanum nitride LaN powder

Overview of lanthanum nitride LaN powder

Lanthanum nitride is a black powder with a chemical formula of LaN and a molecular weight of 152.91g/mol. Lanthanum nitride lantln_num nilridc La}l melting point? 4}(1 L. Cubic crystal system Chau}cl type structure'. It has ionic plastic bond. It is easy to decompose in high overflow and stable humid air, soluble in acid, and hydrolyzed by alkali. F} The preparation method of oxides emitting ammonia is the same as that of nitriding persimmon.

LAN is unstable and easily oxidized into powder in the air. It decomposes in high humidity or humid air, dissolves in acid, and releases ammonia and alkali.

Production method of lanthanum nitride LaN powder

The dehydrated chloride is dissolved in methanol, and electrolysis is carried out with a graphite anode (d=12mm) and a mercury cathode. The electrolysis vessel is equipped with multiple ground glass joints for inserting the graphite anode, agitator, and N2 gas conduit. The inlet and outlet, the water jacket and the piston at the bottom. The voltage is 40V to ensure a current of 1~2A. The size of the current depends on the distance between the anode and the cathode (10~20mm). The concentration of rare earth chloride is half-saturated, and the temperature is about 20°C. Since the surface area of the cathode used in the reaction is relatively large, a current of 1A corresponds to a current density of 0.04A/cm2. After 20-40 hours of electrolysis, the amalgam alloy flows into the container of two spherical tubes. Wash off impurities with methanol under N2 atmosphere. The unreacted mercury passes from the spherical tube 1 to the spherical tube 2 by distillation, and the connection of the spherical tube is disconnected. The composition of the amalgam alloy in tube 1 depends on the temperature of mercury distillation (200-300°C). 2. Mix rare earth metal and mercury in a glass tube at 300～350℃ to make an amalgam (the amount of mercury is 20-30 times that of rare earth metal). Metal can be purified while forming amalgam, because rare earth metal oxides are lighter than mercury and will float on the surface of amalgam. The obtained thick paste-like solid, namely amalgam, can be directly used for the nitridation reaction. Nitridation reaction of amalgam alloyThe amalgam alloy is placed in two Mo boats in the quartz tube. Only 1/5 of the amalgam is placed in the first Mo boat. This is done to further purify the N2 passed in, because The product LnN can absorb trace amounts of O2. When N2 is introduced, the temperature control is carried out according to the following steps: 340℃ 2～3h, 500℃ 2～3h, 700℃ 12～15h, 1000℃ 1～5h. Do not use rubber tubing or plastic tubing (both are easy to seep water) for N2 conduits, and glass tubing should be used for all connections.
