New Method for Synthesis of Strontium Titanate

Abstract

A new method is presented for synthesizing strontium titanate. The reaction between strontium nitrate and meta-titanic acid or titanium dioxide (anatase or rutile) has been studied with use made of thermo-gravimetry and differential thermal analysis, and the compound produced was identified by X ray diffractometry. A mixture of strontium nitrate and meta-titanic acid is converted to strontium titanate at about 600°C by an apparently endothermic reaction. This process can be applied advantageously to the preparation of sources of radiation and heat that utilize radioactive strontium obtained from nuclear fission products.
