개요
BaSiO3 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.
화학적 성질
Colorless powder. Insoluble in water; soluble in acids.용도
Barium silicate films that are suitable for use as transmission media in integrated optical circuits. It is shown that the films, which can be produced with a wide range of refractive indices by suitable selection of the ratio of the target constituents, exhibit low optical attenuation. Hence it is used for integrated optical circuits. It is used in ceramics.제조 방법
Bariumsilicate can be prepared by calcining the oxide with silica, SiO2, at an elevated temperature: BaO + SiO2 + hea?BaSiO3메타규산염 바륨 준비 용품 및 원자재
