Strontium Titanate(SrTiO3)

Strontium titanate is basic Inorganic Dielectric Material with excellent dielectric properties, temperature characteristics, optical characteristics, and electrostatic properties.
It is widely used in the fields of ceramic capacitors, PTC thermistors, varistors, optical glass and the carbon powder performance improvement.
Under the system of strict quality control, our Strontium titanate is of great high and stable quality by the use of solid-phase synthesis technology.
To meet the different needs of customers, we, together with the Technology Elites in dielectric ceramic material and its applications domain, mainly produce three series of strontium titanate according to specific requirements in the application.
