Synthetic method of praseodymium nitride

1 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, N2 pipe, and water jacket. And the piston at the bottom. The voltage is 40V to ensure a current of 1~2A. The magnitude of the current depends on the distance between the cathode and anode (10~20mm). The concentration of rare earth chloride is half-saturated, and the temperature is about 20°C. Because 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 a container composed of two spherical tubes. Wash off impurities with methanol in a N2 atmosphere. 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 In the glass tube at 300～350℃, the rare earth metal is in contact with mercury (the amount is 20-30 times that of the rare earth metal). The amalgamation can also purify the metal, because rare earth metal oxides are lighter than mercury and will float on the surface of the amalgam, thus obtaining a thick paste-like solid, the amalgam, which can be directly nitrided reaction. The nitriding reaction of the amalgam alloy is as follows.

The amalgam alloy is placed in two Mo boats in the quartz tube. The first one contains 1/5 of the amalgam to further purify the N2 introduced, because the product LnN can absorb trace amounts of O2. When N2 is introduced, the temperature should be controlled according to the following requirements: 340℃ for 2～3h, 500℃ for 2～3h, 700℃ for 12～15h, 1000℃ for 1～5h. Do not use rubber tubing or plastic tubing (both are easy to seep water) for N2 conduits, and use glass tubing for all connections.

Overview of nitriding PrN powder

Nitrided PrN powder is a chemical substance with a chemical formula of PRN and a molecular weight of 154.91 g/mol. It is a silver-white medium soft metal element and lanthanide element. Its atomic number is 59 and it is a rare earth metal. Like other rare earth elements, its toxicity is very low and it is not necessary for living things. We provide high-quality PRN powder with high purity, ultra-fine particle size and larger surface area.
