Thallium
Thallium oxide is used to produce special glass with a high index of refraction, and also low melting glass that becomes fluid at about 125K. An alloy of mercury containing 8% thallium has a melting point 20°C lower than mercury alone. This can be used in low temperature thermometers and switches. Biological role.
