Tsis tshua muaj ntiaj tebyog lub npe sib sau ua ke ntawm 17 lub ntsiab lus hlau, lub npe hu ua "cov vitamin niaj hnub", yog ib qho tseem ceeb ntawm cov khoom siv pob zeb hauv Suav teb, tau siv dav hauv kev tiv thaiv hauv tebchaws, aerospace, cov ntaub ntawv tshwj xeeb, metallurgy, lub zog thiab kev ua liaj ua teb thiab ntau lwm yam.Tuam Tshoj yog lub ntiaj teb loj tshaj plaws tsawg lub ntiaj teb reserves thiab ntau lawm lub teb chaws, ntawm uas Baotou lub nroog nyob rau hauv Inner Mongolia autonomous cheeb tsam muaj 83.7% ntawm lub teb chaws reserves, 37.8% ntawm lub ntiaj teb no reserves, Bayan Obo mine yog lub ntiaj teb no loj tshaj plaws tsis tshua muaj av mine.
Cov hlau tsis tshua muaj hauv ntiaj teb thiab lawv cov alloys ua lub luag haujlwm deoxidation thiab desulphurization hauv steelmaking, uas tuaj yeem txo cov ntsiab lus ntawm ob qho tib si kom tsawg dua 0.001%, hloov cov duab ntawm cov khoom sib xyaw, ua kom cov nplej zoo dua, txhawm rau txhim kho kev ua haujlwm ntawm cov hlau, txhim kho lub zog, toughness, corrosion kuj thiab oxidation kuj.Tsis tshua muaj lub ntiaj teb hlau thiab lawv cov alloys yog siv nyob rau hauv kev tsim cov nodular cam khwb cia hlau, high-strength grey cam khwb cia hlau thiab vermicular cam khwb cia hlau, uas tuaj yeem hloov daim ntawv ntawm graphite hauv cam khwb cia hlau, txhim kho cov txheej txheem casting, thiab txhim kho cov khoom ntawm cam khwb cia. hlau (alloy steel, cam khwb cia hlau).
Tsis tshua muaj lub ntiaj teb polishing hmoov yog siv los txhuam ntau yam iav, CeO2 yog siv los decolorize iav thiab txhim kho nws cov pob tshab.Pr6O11, Nd2O3, thiab lwm yam., siv rau iav xim;La2O3, Nd2O3, CeO2, thiab lwm yam yog siv los tsim cov iav tshwj xeeb;Hauv kev lag luam ceramic, tsis tshua muaj lub ntiaj teb tuaj yeem siv los ua cov iav glazes, refractories thiab cov ntaub ntawv ceramic.Ib qho siab purity tsawg lub ntiaj teb oxides xws li Y2O3, Eu2O3, Gd2O3, La2O3, Tb4O7 yog siv los ua ke ntau yam khoom siv fluorescent, xws li xim TV liab phosphor, projection TV dawb phosphor, ultra luv persistence phosphor, ntau yam teeb phosphor, X- ray enhanced npo phosphor thiab lub teeb hloov dua siab tshiab cov ntaub ntawv fluorescent.
Cov hlau tsis tshua muaj hauv ntiaj teb yog ib feem tseem ceeb ntawm cov khoom siv high-tech niaj hnub no.Ib tug series ntawm compound semiconductors, electro-optical cov ntaub ntawv, tshwj xeeb alloys, tshiab functionality cov ntaub ntawv thiab organometallic tebchaw muaj li ntawm tsawg lub ntiaj teb hlau thiab non-ferrous hlau yuav tsum muaj tsawg lub ntiaj teb hlau nrog nws cov yam ntxwv.Tus nqi yog me me, tab sis nws tseem ceeb heev.Yog li ntawd, nws yog dav siv nyob rau hauv niaj hnub kev sib txuas lus technology, hluav taws xob computers, aerospace txoj kev loj hlob, tshuaj thiab kev noj qab haus huv, photosensitive cov ntaub ntawv, photoelectric cov ntaub ntawv, lub zog cov ntaub ntawv thiab catalyst cov ntaub ntawv.Tuam Tshoj yog nplua nuj nyob rau hauv lub ntiaj teb tsis tshua muaj hlau minerals, uas muab kev pab zoo dua rau txoj kev loj hlob ntawm tsawg ntiaj teb hlau kev lag luam.
