Higher melting point gold or gallium

Elemental gallium is not found in nature, but it is easily obtained by smelting. Very pure gallium is a silvery blue metal that fractures conchoidally like glass. Gallium liquid expands by 3.10% when it solidifies; therefore, it should not be stored in glass or metal containers because the container may rupture when the gallium changes state. Gallium shares the higher-density liquid state with a sh… WebGallium: 29.76 °C: Lutetium: 1663 °C: Roentgenium: N/A: Germanium: 938.3 °C: Hafnium: 2233 °C: Copernicium: N/A: Arsenic: 817 °C: Tantalum: 3017 °C: Nihonium: N/A: …
