BARIUM SILICATE Usage And Synthesis
  • DescriptionBaSiO3 is orthorhombic with unit-cell dimensions of a = 5.6182(5)?, b = 12.445(1), c = 4.5816 ?. It is dimorphic with α-BaSiO3 stable below about 990°C but forms β-BaSiO3 above 1000°C. A 1:1 mol ratio of BaO–SiO2 fired at 850°C and 1050°C serves to form the two dimorphs.
    The enthalpy of solution of BaSiO3 in (3.15 mol/dm3 HF + 8.13 mol/dm3 HCl) has been measured. From the results, the standard molar enthalpy of formation of BaSiO3 (s) was calculated. The value obtained was -1606.4±2.6 kJ/mol.
  • Chemical PropertiesColorless powder. Insoluble in water; soluble in acids.
  • UsesIn ceramics.
  • PreparationBariumsilicate can be prepared by calcining the oxide with silica, SiO2, at an elevated temperature: BaO + SiO2 + hea?BaSiO3
