Chinese name: yttrium silicide
English name: YTTRIUM SILICIDE
CAS：12067-55-9
EINECS:235-080-8
Chemical formula: Si2Y
Molecular weight: 145.08
Melting point: 1520 ℃
Density: 4.39 g/cm3
Crystal system: low-temperature orthorhombic crystal system, high-temperature tetragonal crystal system
Resistivity: The resistivity is greater than that of yttrium metal. The resistance temperature coefficient is positive, but it is negative at 500 ℃.
It is easy to react with hydrochloric acid and hydrofluoric acid, and is insoluble in H2O.
