Tungsten telluride powder is an inorganic compound powder composed of two elements, tungsten (W) and tellurium (Te).
Basic properties:
Chemical formula: WTe₂.
Molecular weight: 439.04.
Appearance: gray-black powder at normal temperature and pressure.
Density: Relatively high, about 9.43g/cm³.
Melting point: high, about 1127℃.
Crystal structure: layered structure. In its orthogonal cell, the tungsten chain is one-dimensional along the A-axis of the tellurium layer. This special structure gives tungsten telluride powder unique physical and chemical properties in certain directions.
Physical properties:
Electrical conductivity: It is a non-magnetic semi-metallic material with good electrical conductivity.
Magnetoresistance characteristics: It has a very large magnetoresistance, and its magnetoresistance characteristics are very unique at low temperature and high magnetic field strength.
Preparation methods: Common preparation methods include powder metallurgy, vacuum melting, chemical vapor deposition, etc.
Powder metallurgy method is to mix tungsten powder and tellurium powder according to a certain proportion, through pressing, sintering and other processes to prepare;
Vacuum melting method is to heat tungsten and tellurium to high temperature in a vacuum environment to melt and then cool and solidify;
Chemical vapor deposition method is the use of chemical reactions to deposit tungsten telluride powder on the substrate.
Application field:
