Ubhedu obucocekileyo obuphezuluibhekisela ekuhlambulukeni kobhedu kufikelela kwi-99.999% okanye ngaphezulu kwe-99.9999%, kunye neempawu zayo ezahlukeneyo zomzimba ziphuculwe kakhulu kunezo ezinobunyulu obuphantsi.Ubhedu lunombane kunye ne-thermal conductivity elungileyo, kwaye luthambile kwaye luthambile.Ubhedu luqhele ukusetyenziswa ukwenza iingcingo kunye neetyhubhu, kodwa lunokucinezelwa, lutsalwe, luphoswe kwiimveliso ezahlukeneyo.Kwiminyaka yakutshanje, ubhedu olucocekileyo lusetyenziswe ngokubanzi kwaye luxabiswa kakhulu.
Ukuba ubhedu olucocekileyo oluphezulu luya kusetyenziswa kwisekethe edibeneyo yezixhobo zomsindo, ukuveliswa kweentambo zomsindo, kuya kuphucula kakhulu ukunyaniseka kwesandi;Iingcingo zegolide zegolide ezisetyenziselwa ukwenza i-semiconductors nazo zingatshintshwa ngobhedu, olugcina iindleko.Ubhedu obusulungekileyo bunobushushu obuphantsi bokuthambisa, i-ductility elungileyo, kwaye inokutsalwa ngokulula kucingo olubhityileyo.Ukusetyenziswa kobhedu obucocekileyo obuphezulu kunokuphucula umgangatho weemveliso ze-elektroniki kunye nokunciphisa iindleko zokuvelisa.
Itekhnoloji yokucoca ubhedu obucokisekileyo buqalwe kwakudala.Ngomnyaka we-1941, i-Smart Jr kunye nabanye baqhuba uphando malunga nokucocwa kwe-electrolytic, bahlambulule kakhulu i-electrolyte, kwaye baqhuba i-electrolysis emininzi edityaniswe nesisombululo se-copper sulfate kunye nesisombululo se-nitrate sobhedu.Imveliso.Ukususela kwiminyaka yee-1950, indlela yokuhlanjululwa kwesinyithi ngokunyibilika kwendawo yavela, kwaye yasetyenziswa ngokukhawuleza ukuhlambulula ubhedu.Ngale ndlela, iteknoloji yokucoca ubhedu yaphuhliswa ngakumbi.Kwiminyaka yakutshanje, indlela yokucoca ubhedu esekelwe kwi-ion exchange ibonakale, kwaye iziphumo ezilungileyo zifunyenwe.Uphuhliso lwetheknoloji yanamhlanje luye lwandisa ngokuqhubekayo iimfuno zezinto eziphathekayo.Ubhedu olucocekileyo oluphezulu luneempawu ezininzi ezintle, ezinokuhlangabezana neemfuno ezininzi zobuchwepheshe besimanje.Iimfuno zobugcisa, kwaye zisetyenziswe kwiinkalo ezininzi, kwaye zifumene iziphumo ezilungileyo.
