Beryllium Tellurite

Description

Berylliumtellurite has themolecular formula of BeTeO3 and the molecular weight of 184.61 grams per mole. It can be prepared by means of the solid-state reaction:
BeO+ TeO2+ heat ? BeTeO3
An inert atmosphere is required. This salt is a metatellurite but its formation and physical properties have not been reported in the literature. If a solution method is used, the result is likely to be quite different in that a hydroxy-tellurite is formed:
BeCl2+ Na2TeO3 ? [Be(OH)]2TeO3
Additionally, this compound can be prepared by reacting tellurium dichloride in a solution of beryllium chloride:
BeCl2 + 2TeCl2 + 4H2O ? Te+ [Be(OH)]2TeO3 + 6HCl
Nonetheless, there is absolutely no description of these compounds in the literature and whether a hydrate appears remains unknown.
