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]

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
