Boron Nitride Crucible
Lub boron nitride crucible yog ua los ntawm boron nitride hmoov tom qab kub nias thiab sintering rau hauv cov khoom blocks, thiab ua tiav raws li qhov loj thiab specifications xav tau los ntawm cov neeg siv khoom.
Hauj lwm lawm
Boron nitride crucible yog tsim los ntawm boron nitride sintering block.
Boron nitride tsis tshua muaj resistant rau kub kub. Nws tuaj yeem tiv taus 1800 degree hauv lub tshuab nqus tsev thiab mus txog 2000 degree nyob rau hauv kev tiv thaiv ntawm inert gases. Nws kuj muaj cov thermal shock zoo heev thiab tsis tawg thaum rhuab sai. Tsis tas li ntawd, tom qab 2 teev ntawm rwb thaiv tsev ntawm 1000 degree, nws yuav tsis tawg tom qab rov ua kom txias thiab cua sov rau ntau pua zaus.
（Boron nitride ceramics hauv kev ua）
Boron nitride ceramics muaj cov tshuaj lom neeg ruaj khov thiab tsis hnov mob lossis kev sib raug zoo nrog cov ntaub ntawv hlau, xws li cov hlau ferrous, hlau, tooj liab, stainless hlau, txhuas, iav yaj, silicon molten ntsev, thiab lwm yam. Cov boron nitride crucible ua los ntawm boron nitride yog txawm tsim nyog tshaj li cov tsoos graphite crucible rau nws kub sintering melting thawv.

Daim ntawv siv:
Boron nitride yog siv nyob rau hauv huab cua kub txog li 1000 degree saum toj no uas oxidative decomposition yuav tshwm sim.
Boron nitride yog ib qho yooj yim kom nqus tau noo noo, boron nitride crucible tsis tuaj yeem khaws cia rau hauv qhov chaw ntub dej, yuav tsum muab tso rau hauv qhov chaw qhuav thiab qhov cua, kaw kev khaws cia.
Boron nitride crucible tsis tuaj yeem ntxuav nrog dej, tuaj yeem ua cov ntawv xuab zeb.
Peb lub tuam txhab muab kev pabcuam boron nitride crucible, nruj raws li cov neeg siv khoom tshwj xeeb thiab qhov ntau thiab tsawg rau kev tsim khoom, txais tos sab laj nrog cov duab kos.
