Tape, plate indium In-00 - indium N4
Stamps India Ин000, Ин00 are made in the form of ingots or pyramids with weight of 0.05 — 1 kg. Other brands — weighing not more than 3 kg. in coordination with the consumer brand of India Ин000 can be supplied with a mass of 20 to 50 g, and produced by Czochralski method by pulling content not exceeding 2.5 kg. of these semi-finished products manufactured in tape or sheet with the required parameters. Indium is prepared from intermediate industrial waste zinc, copper, lead and tin. Despite its meager content (to 0.1%) and its separation from cadmium, copper, zinc, antimony and other — rather difficult occupation, it’s worth it: it indium in very high demand. The first concentration is its separation from zinc, cadmium, and copper.
The raw material is treated with sulfuric acid, dissolving metals and by hydrolytic deposition stands out a concentrate, which is achieved due to the change of acidity of the solution. Precipitated cadmium hydroxide at pH 8, hydroxide of copper and zinc, with 6. For the «planting» of indium hydroxide is required indicator of solution pH to increase to 4. «Rough indium» is recovered by cementation from concentrate on aluminum and zinc, and «clean India» is produced by refining with the use of zone melting.

Indium sheet is used in many sectors — electronics, electrical engineering, nuclear power engineering and experimental physics where important a large cross section to capture thermal neutrons. Indium sheet is used in electroforming in the production of electrodes. The interaction of mercury oxide with indium on the electrochemical level applied in high-energy batteries. Indium tape is designed for sealing gaskets in the sealing process of particle accelerators and spacecraft. Together with silicon and germanium the tape used in the manufacture of semiconductors.
Indium is supplied in the vehicles covered. With the help of rail transportation are transported in small parts. Stamps India Ин00, Ин00 come in the form of pyramids or bars, weighing 0.05 to 1 kg. Other brands — less than 3 pounds. Surface samples India may have bumps and shrink holes. Each of the bars marked. Indium bullion brands Ин000, Ин0000 packaged separately, each in plastic wrap and brand Ин00, Ин0 can be folded in pairs. Indium wire is stored indoors in the original packaging, insulated from contact with dust and aggressive environment. Warranty period of storage — 5 years.
