cadmium sulfide
Quick Summary
Cadmium sulfide (CdS) is a yellow-brown, poisonous salt used in electronic components, photoelectric cells, and medicine. It is a binary crystal, meaning it is composed of two elements, and can crystallize in different structures, such as zinc blende or wurtzite. Cadmium, the metallic element in cadmium sulfide, is a rare metal discovered in 1817. It is soft, silvery-white, and can be rolled into sheets. Cadmium is toxic when inhaled as vapor or dust. Cadmium sulfide is known for its color stability and resistance to sulfur and oxidation, making it a valuable pigment.123

At room temperature, cadmium sulfide may crystallize either in the zinc blende or wurtzite structure. Alumina also has two possible structures at room temperature, Ī±-alumina (corundum) and Ī²-alumina. Other binary crystals exhibit different structures at different temperatures. Among the most complex crystals are those of silicon dioxide (SiO2),ā¦
