- Indium (In) Metal Description:
Indium is a ductile, malleable, silvery-white metal; softer than lead. Pure indium emits a high-pitched "cry" when bent. It is unaffected by water and very stable in air. Most often associated with zinc, indium is also found in iron, lead, and copper ores, and is about as abundant as silver.

- Indium (In) Metal Supply & Demand Shortage Developing:
"The UNEP identifies indium as an example where demand is provisionally predicted to grow strongly, with the 1,200 tonnes needed in 2010 increasing to 2,600 tonnes by 2020. Used in producing light emitting diodes and transparent electrodes for flat screen displays, the UNEP says that under one per cent of indium demand is currently recycled. Claire Mikolajczak, director of metals and chemicals at materials supplier Indium Corporation, concedes that flat screens aren't being recycled, but argues that 65 per cent of indium supply currently comes from recycling 'spent' indium material used in manufacturing. 'This recycling ratio will stay constant or improve, so virgin production will need to be increased, but not by such high numbers,' she says." 20 May 2010 Source: UNEP
2) Existing primary capacity is in excess of current production so output could meet the forecast growth in demand in the short term. However, if total indium demand grows at the forecast rate of 15%py to 2015, production could struggle to keep pace. In this scenario prices for indium could reach US$850/kg by 2013.
