Barium Tellurite Usage And Synthesis

Description

Barium tellurite has the molecular formula of BaTeO3 and the molecular weight of 265.4015 g/mol. Its CAS number is 58440-17-8. It can be formed via the solid-state reaction:
BaO+ TeO2 + heat ? BaTeO3
An inert atmosphere is required. This salt is a metatellurite. A series of BaO–TeO2 binary ceramic compounds were explored for microwave dielectric applications with ultralow processing temperatures. During the calcination of mixed BaCO3 and TeO2 raw powders, BaTe4O9, BaTe2O6, BaTeO3, and Ba2TeO5 phases were obtained through the sequential phase formations from Te-rich to Ba-rich phases at temperatures ranging from 500 to 850°C. Sintering temperatures were as low as only 550°C for the Te-rich phases. Barium tellurate ceramics exhibited excellent microwave dielectric properties with intermediate dielectric permittivities and high-quality factors (Q).

Uses

Barium tellurite has not found much usage in industry but is available commercially. In spite of the extensive study of barium tellurite as a component of tellurite glasses, the physical properties such as melting point, etc. are not available.
