WebA liquid metal is a metal or a metal alloy which is liquid at or near room temperature.. The only stable liquid elemental metal at room temperature is mercury (Hg), which is molten above −38.8 °C (234.3 K, −37.9 °F). Three more stable elemental metals melt just above room temperature: caesium (Cs), which has a melting point of 28.5 °C (83.3 °F); … WebNot because of its density or smelly compounds, but because of its high melting point. Very high - over 3 thousand degrees C. After Thomas Edison produced the first commercial electric light in 1879, the race was on to improve on his design - for starters there was the filament - the bit that glows to produce the light but, crucially, doesn't melt.

WebOne of the thermometric fixed points required to realize the International Temperature Scale of 1990 (ITS-90) is that of the ga llium melting point [Ga MP (29.7646 °C)] [1]. The Ga MP is realized by using fixed-point cell containing high-purity (≥99.999 99 wt. % pure) gallium metal with an inert gas pressure of 101325 Pa.
