Strontium titanate

Химические свойства

Powder. Insoluble in water and most solvents.

Характеристики

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℃.

Использование

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.

Методы производства

The single crystal is grown by the Verneuil method by melting using oxygen-hydrogen flame.
