| Analysis of Indium Resource Supply and Consumption Pattern |
| Indium is an important strategic metal in the 21st century and is widely used in the production and manufacture of ITO targets, compound semiconductors, solders, and alloys. By considering the indium industry chain, this study analyzed global supply and consumption of indium since 2000. This study considered the future supply and demand trends, and concluded the following: (1) Global supply of secondary indium has exceeded that of primary indium. Primary indium sources are highly concentrated in China, South Korea, Japan, and Canada, whilst secondary indium sources are concentrated in Japan and South Korea. (2) Global indium consumption has quadrupled in the last two decades. Japan and South Korea are the main consumers of global indium resources, with ITO targets the main consumption area. (3) Since 2007, the global supply of indium has exceeded global consumption by 600 tons. The excess is predicted to enter national reserves. (4) China can learn from the experiences of Japan and South Korea to increase their future supply of indium, reuse indium from the social stock, and improve the utilization efficiency of the indium industry chain. |
