Gallium Ingot

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 termperatures. It may be undercooled to almost 0 °C without solidifying and is more dense as a liquid than solid. Soluble in acid, alkali and slightly soluble in mercury. Reacts with most metals at high temperatures.

Beginning with its discovery in 1875 through the era of semiconductors. Gallium has been used primarily as an agent to make alloys that melt at low temperatures from its discovery in 1875 into today's era of semiconductors. Gallium has a prominance today in the manufacture of semiconductors, including use as a dopant. Most of the gallium produced today is used in electronics. Gallium Arsenide (GAs), the primary chemical compound of gallium in electronics, is used in microwave circuits, high-speed switching circuits, and infrared circuits. Gallium nitride and indium gallium nitride, minority semiconductor uses, produce blue and violet light-emitting diodes (LEDs) and diode lasers.

ESPI supplies Gallium Rod, Shot, Ingots and Gallium Compounds and express ships these forms in ice packed packaging in order to maintain the manufactured integrity.
