Siab -Purity Lanthanum Hlau
Lanthanum Hlau yog ib qho mos mos, malleable, thiab reactive tsis tshua muaj lub ntiaj teb cov khoom siv feem ntau siv los ua cov khoom siv ntxiv, cov khoom siv catalyst, thiab cov khoom siv raw rau cov khoom siv ua haujlwm siab heev. Ua los ntawm molten ntsev electrolysis, peb lanthanum hlau ingots thiab chunks yog tiav thiab ntim nyob rau hauv kev tswj inert ib puag ncig kom txo atmospheric oxidation. Tsim los rau kev lag luam metallurgy, siab -kev ua tau zoo roj teeb tsim, thiab cov iav tshwj xeeb tsim, nws muab nruj tswj cov kab tsis huv kom ua tau raws li qhov xav tau ntawm cov qauv metallurgical thiab kev ua raws li thoob ntiaj teb nrog rau EU REACH thiab US TSCA.
Cov yam ntxwv tseem ceeb
High Metallurgical Purity:Muaj nyob rau hauv cov qauv purities txog li 99.9% (La / TREM) nrog tag nrho lub ntiaj teb tsis tshua muaj purity tshaj 99.95%.
Tswj Trace Impurities:Cov ntsiab lus ntawm cov pa nruab nrab qis thiab nruj me ntsis saib xyuas tsis yog - tsis tshua muaj lub ntiaj teb hlau impurities (Fe, Ca, Mg, Si) tau txheeb xyuas los ntawm kev tshaj spectrometry.
Inert Ntim:Nqus - kaw hauv aluminized ntawv ci nyob rau hauv siab -purity argon los yog submerged nyob rau hauv cov roj ntxhia los tiv thaiv oxidation ntxov ntxov thaum caij tsheb.
Flexible Forms:Muab raws li tawg ingots, txiav daim, thiab kev cai rods tailored rau tshwj xeeb induction melting los yog alloying txheej txheem.
