Calcium fluorosilicates: The Ca6-0.5xSi2O10-xFx phase

The identity of Ca 6 0 5 Si201~ F with other germanate1 X ~ 1 Xand silicate phases r~ported in the literature is confirmed by X-ray methods. The crystals exhibit superstructure which is interpreted as arising from ordering of Ca vacancies in the [203] direction. Its crystallochemical relationships...

Sumario:The identity of Ca 6 0 5 Si201~ F with other germanate1 X ~ 1 Xand silicate phases r~ported in the literature is confirmed by X-ray methods. The crystals exhibit superstructure which is interpreted as arising from ordering of Ca vacancies in the [203] direction. Its crystallochemical relationships with other fluorosilicate and germanates is discussed.
