It is more precious than silver but with prices more volatile than gold. Platinum has broad chemical resistance although the metal may be dissolved in aqua regia, a highly acidic mixture ... WebConsequently, once melted, Ga and many of its alloys remain liquid at or below room temperature. For example, for months researchers in my laboratory have left EGaIn in a freezer at −15 °C—a remarkable 30 °C below the material’s melting point. It has yet to freeze. The supercooling effect becomes even more pronounced in small particles.
