Calcium Metatitanate, CaTiO₃

Calcium Metatitanate, CaTiO₃, is found naturally as the mineral perowskite, density 3.97 – 4.01. It may be obtained artificially by fusing titanium oxide and calcium carbonate with potassium carbonate or calcium chloride. There are probably two modifications of the titanate. At high temperatures it forms homogeneous solid solutions with calcium silicate, but at lower temperatures, when wollastonite is formed, the solutions split up into their components.
