Is gallium a liquid at room temperature
WebApr 3, 2024 · The melting points for gallium and indium, 29.8 and 156 °C respectively, decrease in a eutectic melt at 15.3 °C, thereby allowing room temperature processing of the liquid alloy. In generating the 2D sheets the structurally ordered self-limiting 2D oxide layer or “skin” which forms on the surface of liquid gallium is important. WebGallium is well known as a metal that has a melting point just above room temperature, which means it can literally melt in your hand. In elemental form, it is relatively non-toxic which means it can be handled without alarm, unlike mercury. But gallium metal has many amazing secrets. It can form incredible alloys with other metals.
