Calcium Tellurite, CaTeO₃

Calcium Tellurite, CaTeO₃, is obtained as a flocculent precipitate soluble in boiling water, by the action of tellurious acid on a soluble calcium salt. It is not readily fusible. Berzelius also mentions two acid salts, CaO.2TeO₂, or CaH₂Te₂O₆, and CaO.4TeO₂, or CaH₂Te₄O₁₀. They melt at white heat, and on cooling form an opaque mass consisting of mica-like scales.
