Cadmium tellurite is the tellurite salt of cadmium, with the chemical formula CdTeO3.

Preparation

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

Properties

Cadmium tellurite is a colourless solid[1] that is insoluble in water.[2] 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.[4][5]
