The space lattice of SrTiO3 belongs to the cubic system, and its calcium titanate type structure (refer to BaTiO3 ) has a lattice constant of a=0.3904 nm at room temperature. Cleavage does not occur.
Powder. Insoluble in
water and most solvents.
Strontium titanate (SrTiO3), an oxide of strontium and titanium, is chosen as the model system for perovskite ceramics because it is stable in the cubic crystal system above-168℃.
Strontium titanium oxide is used in tunable microwave capacitors, flat panel displays, field emission displays, microwave solitons, PTC thermistors and varistors, magnetic field insensitive thermometers, ultralow-temperature scanning microscopes, semiconductive ceramics, pyroelectric far-infrared detectors and in alloy and catalyst applications. Due to its high melting point and insolubility, strontium titanate has been used as a strontium-90-containing material in radioisotope thermoelectric generators.
In electronics and electrochemical insulation; in photocatalysis; sputtering target for thin film capacitors; substrate for epitaxial growth of high temperature superconductor thin films. Diamond simulant gemstone.
The single crystal is grown by the Verneuil method by melting using oxygen-hydrogen flame.
