The cytotoxicities of mercury (II) nitrate, gallium (III) nitrate, and indium (III) nitrate were assessed at concentrations between mmol/L and mmol/L, using L929 mouse fibroblasts and the 3 (4,5 dimethylthiazol 2 yl) 2,5 diphenyl tetrazolium bromide (MTT
Indium salts color the Bunsen flame a deep blue violet. Indium phosphide, arsenide, and antimonide are semiconductor materials used in photocells, thermistors, and rectifiers. Indium is found in very low concentrations in many ores and minerals; it was first found in zinc blende and is produced commercially as a byproduct of the smelting of zinc.
Abstract. Neutron activation analyses of gallium, germanium, indium, and iridium in eight lunar samples andin meteorites androcks (including four calciuln rich achondrites and five terrestrial basalts) with similar bulk compositions are re ported. Lunargallium concentrations are remarkably constant at
Indium and gallium are metals of very low abundance in the Earth's crust and, correspondingly, the bio sphere is only adapted to very small concentrations of these elements. However, in modern semiconductor indus tries both elements play a central role and

Finely divided indium metal dust or powder may be flammable or explosive when dispersed in the air at high concentrations and exposed to heat, flame, or other ignition sources. Explosions may also occur upon contact with certain incompatible materials (see Stability and Reactivity, Section 10).
14/5/1985 · Gallium and/or indium adsorbed on the chelate resin is desorbed by eluting with a mineral acid. The eluate, after the pH adjustment, is passed through another bed of a chelating ion exchange resin having an amino carboxylic acid group, and the resin is treated with a mineral acid to elute the metal ions adsorbed on the resin to thereby recover gallium and/or indium in the form of a
