Synthesis method of vanadium silicide
In a direct current plasma arc furnace, the elemental powders of V and Si are heated.
Description of vanadium silicide
Vanadium is a chemical element, the symbol is V, and the atmospheric number is 23.
It is a hard, silver-gray, ductile and ductile transition metal.
Elemental metals are rarely found in nature, but once artificially isolated, the formation of an oxide layer (passivation) stabilizes the free metal to a certain extent and prevents further oxidation.
Many known metal Si compounds, their bonding range from metal to ion and covalent.
Overview of vanadium silicide VSi2
Vanadium silicide, the chemical formula is VSi2. The molecular weight is 107.11. Metal prismatic crystals. The relative density is 4.42, insoluble in dry water and cold water, soluble in dry hydrofluoric acid, insoluble in dry 7 alcohol, 7 ml and acid. Vanadium silicide is often used to make acid-resistant refractory materials.
Application of vanadium silicide VSi2
Silicide VSI2 powder vanadium has good oxidation resistance and corrosion resistance. It is widely used in high-temperature structural materials and ultra-large-scale integration.
1. Preparation of vanadium silicide film. By injecting high current density vanadium metal ions into silicon, thin silicides with good performance can be directly synthesized. The sheet resistivity of high beam density implantation and high temperature annealing (1200℃) is still very low, which fully shows that vanadium silicide has good thermal stability. Transmission electron microscope observation shows that the thickness of the continuous thin layer of vanadium silicide is 80nm.
2. Vanadium silicide is a sound-absorbing ceramic material. The sound-absorbing surface layer is coated on the surface layer of the base layer to prepare a sound-absorbing ceramic material with sound-absorbing function and good dust-proof and fire-proof performance. Performance and service life are greatly extended.
