Titanium dioxide for piezoceramics
Titanium dioxide is colourless high heat crystals (a melting temperature is 1870 °C) becoming yellow when heating in air. It is insoluble in water and diluted mineral acids (except fluorhydric acid). It is found in the forms of rutile, anatase or brookite which irreversibly turn into rutile when heated above 1000 ° C.
