Lub lim tiam no (8.7-8.11, tib yam hauv qab), txawm hais tias tag nrho cov kev ua lag luam tsis tshua muaj, nrog rau kev tsis txaus siab muag, tsav tsheb mus rau lub patnable patsis tus nqi. Qee qhov sib cais thiab qhov kev hloov pauv ntawm cov khoom lag luam hlau nrog kev thov tsis muaj zog thiab sib zog ruaj khov cov nqi ntawm cov khoom lag luam.
Thaum pib ntawm lub lim tiam, kev ua lag luam pib nrog lub sijhawm pib ruaj khov, nrog cov kev lag luam ruaj khov, feem ntau ntawm cov sab nraud, feem ntau ntawm cov nqi tsawg los ntsuas lub zog. Raws li ib qho me me ntawm kev sib pauv tus nqi sawv, tus nqi qis ntawmPreaseymiumthiabneodymiumpib ua kom nruj thiab cov lus hais kom txav mus ib txhij. Nyob hauv nruab nrab ntawm lub lim tiam, kev nug kev lag luam zoo siab tau nce, thiab kev txaus siab ntawm cov kev txiav txim siab tau yog tsawg, ua rau kev caum cov nqe lus thiab ib qho kev hloov pauv me me. Raws li preaseodymium thiab neodymium oxide ib zaug ntxiv mus kuaj 580000 yuat Lub lim tiam no, zawm ntawm cov nqaij xaj ntawm cov khoom siv hlau tau ua rau kom txo qis hauv kev kam lees txais cov xaj kom ntau. High qib ntawm oxides kuj tseem pom tau ceev faj hauv kev yuav khoom raw. Tsuas yog rau tsawg tus naj npawb ntawm cov neeg yuav khoom tshiab ntau, hauv qab kev ua tau zoo tau tsis muaj neeg.
Lub lim tiam no, cov oxide ntawm preasodymium neodymium thiab dysprosium tseem ruaj khov thiab upward, nrog xov xwm rub. Cov nqaij tawv ruaj khov ntawm erbium thiab holmium ua rau tus nqi yuav nce synchronously. Txawm li cas los xij, tib lub sijhawm, nrog kev thov nyuaj los txhawb, kev sib pauv tom qab kev cia siab, ua rau tos-thiab-pom qhov xwm txheej nce ntxiv.
Los ntawm sab nraud qauv ntawm lub sijhawm ruaj khov thiab tsis hloov oxides lub lim tiam no, nws tuaj yeem pom tau tias cov tuam txhab sib cais tsis kam lees tus nqi txawm tias tus nqi siab thiab muaj zog pov tseg. Txawm li cas los xij, kev lag luam cov tuam txhab tau maj mam hloov pauv lawv lub tswv yim thaum lub lim tiam - cov nyiaj tau los tau nce.
Raws li lub Yim Hli 11, cov lus hais rau qee cov khoom lag luam tsis tshua muaj nyob nruab nrab ntawm 0.45 lab yuan / tuj ntawmLanthhanum oxide; Cerium oxide: 42-4600 yuan / tuj;Inaseodymium neodymium oxideyog 475-478 txhiab yuan / nyhav ib tuj / tuj, muaj kev nce ib hlis ntawm 1.65%;Tus lej xide prase49-495 txhiab yuan / tuj,neodymium oxide 49-495 txhiab yuan / nyhav ib toos; 585000 txog 59000 yuan / tuj ntawm hlau preaseMium neodymium,; 2.33-2.35 lab yuan / tuj ntawmdysprosium oxide; 717-7.25 lab yuan / tuj ntawmterbium oxide; 223-22.5 lab yuan / tuj ntawm dysprosium hlau;Hlau terbium915-9.35 lab yuan / tuj;Gadolinium oxide: 268-273000 Yuan / Tuj; 253-25800 yuan / tuj ntawm Gadolinium hlau; 55-56000000 yuan / tuj ntawmHolmium oxide; Erbium oxideyog 27000-275000 yuan / tuj.
