Nature and stability: It will not decompose when used and stored according to specifications. CoSi2 can react with hot hydrochloric acid, soluble in hydrochloric acid but insoluble in sulfuric acid. Can be corroded by aqua regia, concentrated nitric acid, strong alkaline solutions, and molten hydroxides and carbonates. Can undergo chemical reactions with hydrogen sulfide, hydrogen fluoride, hydrogen chloride, fluorine, chlorine, etc. 
Synthesis method: 
Mix cobalt powder and silicon powder evenly according to the chemical composition ratio of CoSi2, melt them under isolated air conditions, and keep them at 1150 ℃ for 100 hours to fully homogenize them. The product is CoSi2 that is close to a single phase. 
Application: Cobalt silicide powder has the characteristics of low resistivity and good thermal stability, mainly used in large-scale integrated circuits. In addition, cobalt silicide has a crystal structure similar to silicon, so it can form epitaxial CoSi2/Si structures on silicon substrates to study the interface characteristics of epitaxial metallic silicon. Cobalt silicide (Cosix) is a widely used material for connecting metals and semiconductors, serving as an inter connect between the semiconductor base electrode and metal wires in devices. 
Storage method: Store in a dry and cool environment, not exposed to air, to prevent moisture from causing oxidation and aggregation, affecting dispersibility and effectiveness of use.
