Colored plates: "Indium" You're Wonderful about Indium Concept Stocks

Indium: With scarce reserves, China is the world's largest producer of primary indium. Indium is a rare metal and its content in the earth's crust is similar to that of silver, which is 1×10-5%, but the yield is only 1% of silver. To date, no single indium or indium-based natural indium deposits have been discovered. Currently, the minerals that have industrially recovered indium value are mainly sphalerite. The world's largest primary indium supplier is indium, with global reserves of approximately 1.6-1.9 million tons and China reserves of 13,000 tons. The supply of indium is mainly divided into primary indium and recycled indium. The production of primary indium mainly comes from China, South Korea, Canada and Ben, and the recycled indium is mainly in Ben, South Korea and China Taiwan. In 2007, the global supply of indium was 1,249 tons, of which 549 tons of primary indium and 700 tons of indium were recycled, and China supplied 249 tons of primary indium.

The liquid crystal display is the main application field of indium currently. In the future, solar thin film batteries and LEDs are expected to become new application industries. At present, ITO (Indium Tin Oxide), which is mainly used to produce liquid crystal displays, accounts for 83% of global indium use. In other fields: compound consumption accounts for 9%, alloys account for 5%, and semiconductor industry accounts for 3%. %. In 2007, the global consumption of indium was 1,325 tons, of which 1,100 tons were used in the ITO industry and 225 tons in other industries. Shenyin Wanguo expects that with the rapid development of solar thin-film batteries and LEDs, the semiconductor industry is expected to become one of the most important application areas of indium in the next phase.

It is expected that the demand for indium will reach 3000 t/year in 2015, and the indium price is expected to return to a reasonable value of US$2,000-3,000/kg. On the one hand, with the wide application of indium in solar thin film batteries, LED and other new fields, the demand for indium is expected to maintain an annual growth rate of 10% to 15%. It is expected that the demand for indium will reach 3000t/year by 2015; On the other hand, with the indium resource country represented by China as its strategic reserve and export quota for indium, the supply of primary indium will gradually tighten and the supply of recycled indium will also have a bottleneck. In the medium to long term, the indica- tion of indium is basically established. According to industry analysts, the reasonable value of indium price should be 2000-3000 US dollars/kg, while the current indium price is only 300 US dollars/kg. Shenyin Wanguo believes that with the mid-to-long term imbalance in supply and demand, indium prices may achieve the future 5- Ten times higher in 10 years.

Where indium is sacred, you may not know much about it. Its main uses are the following:

First, for indium-tin-oxide, ITO commonly known as indium tin oxide, application industries: thin film crystal, liquid crystal display, plasma display. Accounted for 83% of global consumption.

Second, the compound consumption field, accounting for 9% of global consumption.

Third, indium telluride / arsenic Indium: infrared detection, optical and magnetic devices, magnetoresistors and solar energy converters. .

4. Indium phosphide is used for microwave communication, laser light source in optical fiber communication and solar cell materials; and selenium indium-copper polycrystalline thin film is used for manufacturing solar cells. Adding indium to the negative electrode material of the battery can play a role of antiseptic.

V. Alloy field, accounting for 5% of global consumption.

6. Silver-lead-indium alloys can be used to manufacture high-speed aeroengine bearings; Indium-tin alloys can be used as vacuum seal materials and low-melting-point alloy contact materials for glass-to-glass or glass-to-metal adhesives; and low-melting-point alloys (eg, The addition of VII or indium to Wood Alloy can reduce the melting point, and the indium has a low melting point and a low degree of indium.

8. Alloys composed of gold, palladium, silver, copper and indium can be used to make dentures and decorations.

Nine, the semiconductor industry, accounting for 3% of global consumption.

With the upcoming ten rare metal storage and storage policies to be announced, ten rare metal related faucets, including rare earth, tungsten, tantalum, molybdenum, tin, indium, bismuth, helium, xenon and zirconium, are worthy of attention. Our Indium Concept Unit 600961 naturally cannot be missed.

Metal indium listed companies refer to listed companies that extract and sell metallic indium. At present, only listed companies include Zhuye Group, Zhongjin Lingnan, Zinc Industry Co., Luoping Zinc, and ST Everest have indium production capacity.
