English name: GADOLINIUM SILICIDE 
CAS： 12134-75-7 
EINECS：235-216-6 
Chemical formula: Gd2Si 
Molecular weight: 342.59 
Density: 5.900 
nature: 
Gadolinium silicide is a solid that often appears as gray or black crystals. 
3. Stable in air and not easily oxidized. 
4. Soluble in concentrated nitric acid, hydrofluoric acid, and dilute hydrochloric acid, but insoluble in organic solvents such as alcohols and ether. 
Gadolinium silicide can be prepared by the following methods: 
1) Reaction method: Mix an appropriate amount of gadolinium and silicon powder in a certain proportion, and react at high temperature to produce gadolinium silicide. 
2) Vapor deposition method: By evaporating or decomposing appropriate amounts of organic silicon compounds and gadolinium compounds, they react at high temperatures to form gadolinium silicide. 
Purpose: 
1) Gadolinium silicide is widely used in the nuclear industry as a reinforcing agent to improve the properties of materials such as ceramics and alloys. 
2) Used for producing catalysts, semiconductor materials, and magnetic materials. 
3) The radioactive properties of gadolinium silicide make it a radioactive tracer and diagnostic tool in the medical field. 
Manufacturing method: 
Security information: 
1) Gadolinium silicide is not a combustible material for the human body, but it should be avoided from contact with acids, oxidants, and organic compounds to prevent the production of harmful gases.
