Strontium titanate nanoparticles
Strontium titanate is an oxide of strontium and titanium.
Strontium titanate nanoparticles appear in the form of a black powder having a spherical surface area.
We at Particular Materials synthesize nano SrTiO3 and we produce dispersions with excellent stability, monodispersity and fully disaggregated state.

Technical Information
Strontium titanate nanoparticles are regarded as ferroelectric materials with their ferroelectricity being sustained at low temperature through quantum functions. They adopt a transitional state to non-ferroelectric property at lower temperatures and are known for their capability as resistive high temperature oxygen sensors.
Strontium titanate are stable without being recrystallize within a wide range of temperatures from as low as 104K to 2300K.
They accept high concentrations of dopants with no phase transition making them qualified sensors over a wide range of temperatures.
In order to be able to take advantage of the various properties of SrTiO3 nanoparticles, significant care needs to be taken in controlling size, monodispersity and crystalline structure.
