Galinstanとは 意味・読み方・使い方

Galinstan is a family of eutectic alloys mainly consisting of gallium, indium, and tin, which are liquids at room temperature, typically freezing at −19 °C (−2 °F). Due to the low toxicity and low reactivity of its component metals, it finds use as a replacement for many applications that previously employed toxic liquid mercury or reactive NaK (sodium-potassium alloy). A typical composition is 68.5% Ga, 21.5% In and 10% Sn, with trace amounts of copper. Its name is a portmanteau of gallium, indium, and stannum (Latin for "tin"). Galinstan is a registered trademark of the German company Geratherm Medical AG.
