Description and Uses

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.
