Recently, Feinan Resources' 4N7 fine indium technical improvement project was officially mass-produced, successfully producing the first batch of high-quality indium ingots with a purity of 99.997%. According to reports, the technical barriers for purifying high-purity indium are extremely high, and there are few domestic enterprises with stable production capacity on a large scale. According to reports, the explosion of artificial intelligence has led to a surge in demand for high-speed optical modules, and indium phosphide substrates have also become just what the industry needs. Currently, global indium ore grades continue to decline and mining costs continue to rise. According to the data, the price of indium climbed all the way from about 2,500 yuan/kg in 2023 to about 5,300 yuan/kg in August 2026, nearly doubling in three years.
