Cov khoom lag luam tseem ceeb siv

Kev Lag Luam Metallurgical:

Hauv kev tsim cov hlau, ntxiv ib qho me me ntawm cov hlua me me tuaj yeem tshem tawm cov teeb meem ntawm cov hlau, thiab phosphorus, kev ua kom muaj zog, nkees tsis kam ntawm cov hlau. Ntxiv cov lus Lanthhanum los nrum cov noob alloys tuaj yeem kho cov nplej thiab txhim kho lub hardness, lub zog thiab tshav kub tawm ntawm aluminium alloys.

Petrochemicals:

Lanthalhanum teb tuaj yeem siv los ua cov khoom siv ntawm cov roj av tawg ua kom muaj kev sib tw, ua rau cov roj ntsha ua rau muaj kev cuam tshuam ntau dua, thiab nce cov txiaj ntsig ntawm lub teeb roj. Ib qho ntxiv, nws kuj tseem tuaj yeem npaj lwm yam tshuaj catalysts, xws li catalysts rau hluavtaws ammonia, organic synthesis thiab lwm yam kev tawm tsam.

Iav thiab Ceramics:

Hauv cov iav tsim tawm, cov roj av hauv tsev tuaj yeem siv los ua cov iav kho qhov muag iav, siab ua kom lub ntsej muag tshiab thiab hluav taws xob-resistant iav. Glass with lanthanum oxide added has a higher refractive index, lower dispersion and good chemical stability, and is often used to make advanced optical lenses, telescope lenses, etc. In the ceramic industry, lanthanum can improve the performance of ceramics, such as improving the hardness, strength, high temperature resistance and insulation of ceramics, and can also be used to prepare functional ceramics with special properties, such as piezoelectric Ceramics, Sib Nqus Ceramics, thiab lwm yam.

Kev Lag Luam Hluav Taws Xob:

Lub ntiaj teb cov khoom siv hluav taws xob tsis tshua muaj cov qauv hluav taws xob thiab cov khoom sib nqus ntawm cov khoom sib nqus, thiab siv dav hauv kev lag luam hluav taws xob. Piv txwv li, cov hlau ua haujlwm tuaj yeem siv los tsim cov khoom siv hluav taws xob, xws li cov khoom siv sib nqus tsis tshua muaj zog, thiab lwm yam siv hauv cov khoom siv hluav taws xob, thiab cov tsheb hluav taws xob, hluav taws xob tsheb, cua tshuab, cua fais fab tiam thiab lwm thaj teb.

Kev tiv thaiv ib puag ncig:

Lanthalhanum tebchaw tuaj yeem siv los kho cov dej khib nyiab thiab cov roj pov tseg. Piv txwv li, Lanthhanum tau siv los ua adsorbent tshem cov kuab paug xws li cov hlau hnyav thiab phosphates nyob rau hauv dej lwg; Lanthhanum oxide tuaj yeem siv rau hauv kev ua pa tawm ntawm cov roj av ua pa tawm los txo cov pa roj av xws li cov pa roj carbon monoxide thiab hydrocarbons hauv kev pa roj.
