strontium titanate has high refractive index and high dielectric constant, which is an important raw material for electronic industry. It is used to automatically regulate heating elements and make components with demagnetizing effect. It can also be used as pigment, enamel, heat resistant materials and insulating materials, and its single crystal can be used as optical materials and artificial gems.


In 1955, the United States National Reed Company made a artificial gem without natural counterpart made by flame fusion method. Its chemical composition is SrTiO3. Barium titanate is an oxide of niobium and titanium. At room temperature, it is a centrosymmetrical paraelectric dielectric material with a perovskite structure. At low temperatures, it approaches a ferroelectric phase transition with a very large dielectric constant of ~10, but remains paraelectric until the lowest temperature measured as a result of quantum fluctuations, making it a quantum paraelectric state. It has always been considered a completely artificial material, until it was discovered in Siberia in 1982 and named as the natural counterpart of tausonite – and has been recognized by the International Mineralogy Association (IMA). Tausonite is still an extremely rare mineral that occurs in very tiny crystals. Its most important application is its synthetic form, which occasionally encounters as a diamond mimic, precision optics, varistors and advanced ceramics
