Description

Thallium is a poisonous, bluish-grey metal that tarnishes quickly in air. Today, thallium doesn't have too many applications due to its toxicity. The metal itself has no commercial value, and very few of its compounds do. Among these, thallium sulphide and oxysulphide are used to manufacture high quality photovoltaic cells, the latter of which has the particularity of being very sensitive to infrared light.

This material data has been provided by Matmatch.

"Typical" values were obtained via a literature search. "Predicted" values were imputed via artificial intelligence technology. While we have placed significant efforts in ensuring data accuracy, "typical" and "predicted" data should be considered indicative and verified by appropriate material testing. Please do contact us if additional information on the the predicted data method is required.
All metrics apply to room temperature unless otherwise stated. SI units used unless otherwise stated.
Equivalent standards are similar to one or more standards provided by the supplier. Some equivalent standards may be stricter whereas others may be outside the bounds of the original standard.
