Gallium highly reactive (rubidium and caesium) nor highly toxic (mercury) and can therefore be used in metal-in-glass high-temperature thermometers. It is also notable for having one of the largest liquid ranges for a metal, and for having (unlike mercury) a low vapor pressure at high temperatures. Gallium's boiling point, 2673 K, is more than eight times higher than its melting point on the absolute scale, the greatest ratio between melting point and boiling point of any element. Unlike mercury, liquid gallium metal wets glass and skin, along with most other materials (with the exceptions of quartz, graphite, and Teflon), making it
Cryogenic Rare Event Search with Superconducting Thermometers Cryogenic Rare Event Search with Superconducting Thermometers The Cryogenic Rare Event Search with Superconducting Thermometers (CRESST) is a collaboration of European experimental particle physics groups involved in the construction of cryogenic detectors for direct dark matter searches. The participating institutes are the Max Planck Institute for Physics (Munich), Technische Universität München, Universität Tübingen, University of Oxford (Great Britain) and the Istituto Nazionale di Fisica Nucleare (INFN, Italy). The CRESST collaboration currently runs an array of cryogenic detectors in the underground laboratory of the Gran Sasso National Laboratory. The modular detectors used by CRESST facilitate discrimination of background radiation events by
