Soluble in hydrochloric acid, insoluble in sulfuric acid. It can be dissolved by aqua regia, concentrated nitric acid, strong alkaline solution, and molten alkali hydroxide and carbon
It is eroded by acid and alkali. It can react with hydrogen sulfide, hydrogen fluoride, hydrogen chloride, fluorine, chlorine, etc.
Synthesis method:
Mix the cobalt powder and silicon powder evenly according to the chemical composition of CoSi2, and melt them under the condition of isolating air
Melt, and keep it at 1150 ℃ for 100h to fully homogenize it, and the product is nearly single phase
CoSi2。
Application: Cobalt silicide powder has the characteristics of low resistivity and good thermal stability, and is mainly used for large-scale integrated power
Road. In addition, cobalt silicide has a crystal structure similar to silicon, so epitaxy can be formed on silicon substrate
CoSi2/Si structure to study the interface characteristics of epitaxial metal silicon. Cobalt silicide (cosix) is a metal and semiconductor
The materials widely used for connection are used as the inter connect between the base electrode of semiconductor and the metal wire
Work in the device.
Storage method: Keep in a dry and cool environment, not exposed to the air, and prevent oxidation and agglomeration due to moisture,
It affects the dispersion performance and use effect.
