Gallium One of four metals which can be liquid at room temperature, gallium has the longest liquid range of any metal (2175 °C). Below its melting point, it is a soft, silvery white metal which is stable in both air and water. Extraction of the element is achieved by electrolytic reduction in aqueous solution. Gallium is used in the semiconductor industry due to its semiconductor properties of alloys formed with phosphorus, arsenic and antimony. It is also used in the manufacture of light emitting diodes and microwave equipment.
