Cadmium tellurite is the tellurite salt of cadmium, with the chemical formula CdTeO3.
Preparation
[edit]Cadmium tellurite can be prepared by the reaction of cadmium sulfate and sodium tellurite in ammonia.
Properties
[edit]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]
