__TOC__

Preparation

Cadmium tellurite can be prepared by the reaction of cadmium sulfate and sodium tellurite in ammonia.

Properties

Cadmium tellurite is a colourless solid that is insoluble in water. It is a semiconductor. It is part of the monoclinic crystal system, with space group P2₁/c (No. 14). It can also crystallize in the cubic crystal system and hexagonal crystal system at temperatures above 540 °C.^{[1] [2]}
