Neodymium Nitride NdN Powder CAS 25764-11-8

Molecular structure and physical properties of neodymium nitride

The chemical formula of neodymium nitride is NdN, in which neodymium atoms form covalent bonds with nitrogen atoms by sharing electrons. The compound is a gray solid at room temperature with physical properties such as high melting point and high hardness. The crystal structure is hexagonal with space group P63/mmc. Each Nd atom forms covalent bonds with four nitrogen atoms, while each nitrogen atom forms covalent bonds with two Nd atoms. This structure gives neodymium nitride a high melting point and hardness, making it stable in high-temperature environments.

Chemical Properties of Neodymium Nitride

At room temperature, neodymium nitride has high chemical stability and does not react significantly with water or air. However, neodymium nitride can react with certain oxidizers at high temperatures to form neodymium trioxide and nitrogen. In addition, neodymium nitride can react with metal halides to form metal nitrides. These chemical properties make neodymium nitride chemically reactive under certain conditions.

Electronic structure of neodymium nitride

The electronic structure of neodymium nitride consists of a neodymium atom 4f75d16s2 and a nitrogen atom 2s22p3. During the formation of covalent bonds, the outer electrons of the nitrogen atom rearrange to form four covalent bonds. This electronic structure gives neodymium nitride a high degree of stability and helps explain its stability at high temperatures and in chemical environments.

How is Neodymium Nitride NdN Powder produced?

High-temperature synthesis: High-temperature synthesis prepares neodymium nitride by heating metallic neodymium and nitrogen in a high-temperature furnace. The advantage of this method is that it can prepare high-purity neodymium nitride, but the required equipment is more expensive and complicated to operate.

Chemical vapor deposition: Chemical vapor deposition is commonly used to prepare neodymium nitride. The method is to prepare a neodymium nitride thin film by chemical reaction between metal halide and ammonia in the reaction gas under certain temperature and pressure conditions. The advantage of this method is that the preparation process can be realized under lower temperatures and pressure, and the reaction conditions can be controlled to prepare neodymium nitride materials with different properties and structures.
