Strontium titanate powder

Product name: Strontium titanate powder
CAS: 12060-59-2
Molecular Formula: SrTiO3
Synonyms: strontium titanate (SrTi03) powder, crystalline strontium titanate SrTi03
Product Description:
A high dielectric constant material (225-250)
Strontium titanate is both much denser (specific gravity 4.88 for natural, 5.13 for synthetic) and much softer (Mohs hardness 6-6.5 for natural, 5.5 for synthetic) than diamond. Its crystal system is cubic and its refractive index (2.41-as measured by sodium light, 589.3 nm) is nearly identical to that of diamond, but the dispersion (the optical property responsible for the "fire" of the cut stones) of strontium titanate is over four times higher, at 0.19 (B-G interval). This results in an excess of fire when compared to diamond.
