Kuhlelo oluqhelekileyo lwamazwe aphesheya, i-zinc yesinyithi inxulumene nonyango lomphezulu kunye nokwaleka, uvavanyo lwemathiriyeli yentsimbi, isinyithi esingenawo intsimbi, izinto zemibhobho kunye nemibhobho, ikhemistri ye-inorganic, iimveliso zekhemikhali, ukubola kwesinyithi, imigodi yesinyithi, iimveliso zetsimbi, irabha, iimveliso zelaphu, ulwelo olugqumayo, isinyithi sesinyithi, isinyithi somgubo, iziqhoboshi, izinto zokwakha, iimveliso zetsimbi ezingenayo intsimbi, iipeyinti neevanishi, izithuthi zendlela, izinto zokugquma, uthungelwano lothumelo lwamandla kunye nothungelwano lokuhambisa, i-optical and Optical measurement, kunye neeminerali ezingezizo ezentsimbi.
Kuluhlu oluqhelekileyo lwaseTshayina, i-zinc yensimbi inxulumene nokukhusela izinto, iindlela zokuhlalutya ze-semiconducting kunye ne-semi-metallic materials, iindlela zokuhlalutya isinyithi esinzima kunye ne-alloys yazo, imibhobho yentsimbi, imibhobho yentsimbi, intsimbi enzima, ukuphosa, ukugubungela izinto ezincedisayo, ezinye iimveliso ezilukiweyo, i-oyile yokugquma, iindlela zokuhlalutya zentsimbi kunye nealloyi zentsimbi, iindlela ezibanzi zokuhlalutya imichiza yesinyithi, iindlela zokuvavanya ukusebenza kweekhemikhali zesinyithi, i-ore yokunxiba i-ore, iindlela zokuhlalutya isinyithi somgubo, ucingo lwentsimbi, intambo yocingo lwentsimbi, ukufulela, ukungangeni kwamanzi kunye nokufuma- Izixhobo zobungqina, izixhobo zesinyithi, ukulinganisa, ulawulo lomgangatho, ukuwelda kunye nokusika, izixhobo ezibanzi zemichiza ekrwada, isinyithi kunye nomgubo wealloyi, izixhobo zesinyithi kunye neemveliso, iziqhoboshi, iintsimbi ezikhanyayo kunye nealloyi zazo, iityuwa ezingaphiliyo, izixhobo zokuhambisa umbane, imilinganiselo yokukhanya. izixhobo, ezinye iiminerali non-metallic, unyango ubushushu, kunye nemigangatho esisiseko kunye neendlela jikelele irabha zokwenziwa.Indlela yokuvavanya esetyenziswe kule vidiyo yi-GB / T 5314 Powder ye-Powder Metallurgy, kunye nendlela yesampuli ... (engakhankanywanga kumbhalo wokuqala).
