CAS number : 12060-08-1
Molecular weight :137.91
Molecular formula/chemical symbol :Sc2O3
Description :
Density:8.35 g/mL at 25 °C(lit.)
Melting Point:1000 °C
Solubility:insoluble in water
Appearance:White powder
USES :
Scandium(III) oxide, Sc2O3, or scandia, is a high melting white solid used in high-temperature systems (for its resistance to heat and thermal shock), electronic ceramics, and glass composition (as a helper material).
Scandium carboxylates may be compounded and sintered with zirconia to produce a scandium stabilized zirconia ceramic (ScSZ) useful as an electrochemical fuel cell electrolyte.
Keywords:oxide;Electronic chemicals;Fine ceramics
