CAS No.: 12067-55-9
Molecular formula: YSi2
Molecular weight: 145.08
EINECS No.: 235-080-8
Properties: orthorhombic system at low temperature and tetragonal system at high
temperature. The melting point is 1520 ℃. The resistivity is higher than that of metal
yttrium, and the resistance temperature coefficient is positive, but it is negative at 500 ℃.
Easy to interact with hydrochloric acid and hydrofluoric acid.
