Calcium titanate, also known as calcium titanium oxide, is a chemical compound with the chemical formula CaTiO3. As a mineral, it is called perovskite, named after Russian mineralogist, L. A. Perovski (1792-1856).

Contents

Use

Calcium titanate can aid integration of bone implants, such as in hip replacement surgery.[1] It has low dielectric loss, especially at microwave frequencies and is therefore used as dielectric material in ceramic capacitors.[2][3]

Formation

It may be formed by the sintering of calcium oxide and titanium oxides.
