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
Ship disposal Ship disposal A number of different methods exist for disposing of a ship after it has reached the end of its effective or economic service life with an organisation. Although many options are technically possible, some, such as deep water sinking, are not used for non-military vessels, or have come under increased scrutiny. Options currently available include: Some shipping companies have in the past attempted to dispose of their ships illegally, often due to the high costs of sanitizing these ships in a legal way as a result of the presence of large quantities of toxic compounds and materials.
