gallium metal Material 99.99% 4n additive of alloy Application gallium metal

1. MATERIAL OVERVIEW Characteristics: Soft silvery-white metal and liquid at the temperature of about 29.76 °C (85.57 °F) or slightly above room temperature. Elemental gallium is a brittle solid at lower termperature.Soluble in acid, alkali and slightly soluble in mercury. Reacts with most metals at high temperatures. Applications: Gallium could be used in different fields, according to its purity. Primarily used in semiconductor and optoelectronic applications, however, it is also used in metal alloying and energy storage applications. 2.
