Cadmium Arsenide

Cadmium arsenide is a compound composed of cadmium (Cd) and arsenic (As) atoms. It has a chemical formula of Cd3As2 and a crystal structure that belongs to the zinc blende type.

Cadmium arsenide is a semiconductor material with a narrow bandgap of about 0.8 eV, which makes it suitable for use in various electronic devices such as solar cells and transistors. However, due to the toxicity of cadmium, the use of cadmium arsenide is limited and efforts are being made to find alternative materials.

In terms of physical properties, cadmium arsenide appears as a dark gray powder or crystalline solid with a density of 5.81 g/cm3. It is insoluble in water but soluble in acids, and can be prepared by reacting cadmium and arsenic at high temperatures.

It is important to handle cadmium arsenide with care as it is toxic and can pose health risks if ingested or inhaled. Proper safety measures should be taken during its handling, storage, and disposal.
