Description:
The metallic thallium is not used anywhere because pure thallium reacts with oxygen and water vapors present in the atmosphere in a very volatile manner and turns into black powdery substance. Thallium is used in conjunction with other metals like sulfur and arsenic for the formation of low melting glasses. These glasses are similar to ordinary glasses and are more durable and insoluble in H2O. One of the most common uses was rat and ant poison, which is now banned. The compounds of thallium like thallium sulfide (TI2S), thallium bromide (TIBr) and thallium iodide (TII) are used in infrared radiation detecting devices. The use of thallium compound, thallium oxide, in making high index refraction glasses and manufacturing photocells is incredible.
