Based on content of indium in zinc ore stocks, there is a worldwide reserve base of approximately 6,000 tonnes of economically viable indium.[11] This figure has led to estimates suggesting that, at current consumption rates, there is only 13 years' supply of indium left.[12] However, the Indium Corporation, the largest processor of indium, claims that, on the basis of increasing recovery yields during extraction, recovery from a wider range of base metals (including tin, copper and other polymetallic deposits) and new mining investments, the long-term supply of indium is sustainable, reliable and sufficient to meet increasing future demands.[13] This conclusion also seems reasonable in light of the fact that silver, three times less abundant than indium in the earths crust,[14] is currently mined at approximately 18,300 tonnes per annum,[15] which is 40 times greater than current indium mining rates."
Azaz ebbol 3-szor annyi van mint ezustbol, csak eddig volt par nagyon olcso banyaszati lehetoseg, mig az olcso ezust lelohelyeket mar a korabbi evszazadokban kimeritettuk. (az emberek odamentek es felszedegettek az ezustot a foldrol) Ha elfogy a jelenlegi olcso keszlet, akkor ugyanugy kell majd banyaszni, mint az ezustot. (hat ez egy hatalmas gondnak tunik...)
Egyebkent jo helyette az aluminium es a gallium is. Ezert is volt jopar regi lcd-ben gallium elektroda (tobbnyire GaAs). Az oled-ekhez meg egyik sem kell, mert azok szerves felvezetokbol vannak, de egy lcd-be is lehet szerves elektrodakat rakni.
Egyebkent a muanyagokhoz jo a legkori szendioxid es a banyaszott szen is. Mindkettobol lehet muanyagot csinalni es ugy nez ki, hogy egyik sem akar tul hamar elfogyni.
