The presence of indium, gallium or iron in macro amounts changes the thallium extraction: at HCI concentration below 7 M thallium co-extraction is observed, the value of D~ is substantially higher than in the solutions containing only thallium. At high HCI concentrations macro elements suppress thallium extraction.

Properties of Gallium | Indium Corporation

Gallium is Unique. In its pure form, gallium is an unusual element to say the least. With a melting point of approximately 30°C, gallium is a liquid at just above room temperature. When alloyed with other elements (notably indium), the resulting melting point is below room temperature. This low melting point has made the gallium alloy family a ...

Gallium - Wikipedia

Gallium is a chemical element with the symbol Ga and atomic number 31. Discovered by French chemist Paul-Èmile Lecoq De Boisbaudran in 1875, Gallium is in group 13 of the periodic table, and has similarities to the other metals of the group (aluminium, indium, and thallium).. Elemental gallium is a soft, silvery metal at standard temperature and pressure.In its liquid state, it becomes ...

Galinstan - Wikipedia

Galinstan is a brand name for a eutectic alloy composed of gallium, indium, and tin which melts at −19 °C (−2 °F) and is thus liquid at room temperature. More loosely, galinstan is also used as a common name for various similar alloys which typically melt at +11 °C (52 °F). Galinstan is composed of 68.5% Ga, 21.5% In, and 10.0% Sn (by weight).
