STRONTIUM TELLURATE Usage And Synthesis

Description

Strontium tellurate has the molecular formula of SrTeO4 and the molecular weight of 279.216 grams per mole. Its CAS number is 15852-10-5. It can be prepared by the solid-state reaction of TeO3 and SrO:
SrO + TeO3+ heat ? SrTeO4
TeO3 melts at 430°C and a temperature of 600°C serves to drive the reaction to completion. This is the tetragonal meta-tellurate composition. It can also be formed in the same manner by solid-state reaction of telluric acid:
SrO(solid) + H2TeO4(solid) ? SrTeO4(solid) +H2O(gas)
This is also tetragonal in structure, with the meta-tellurate configuration. Of the two possible configurations, the meta-tellurate is said to be the most stable. Telluric acid is soluble in water and produces Te(OH)4O^2- anions in solutions. If strontium chloride is added, the product is a tetrahydrate:
SrCl2(aq) +H2Te(OH)4(aq)? SrTeO2(OH)4
