Qhov Tsis Paub Ntawm Boron Nitride Sublimation Boats

Qhov Tsis Paub ntawm Boron Nitride Sublimation Boats

Boron Nitride (BN) sublimation nkoj yog siv nyob rau hauv ntau yam kev siv kub, xws li tshuaj vapor deposition, thermal evaporation, thiab lub tshuab nqus tsev cov txheej txheem. Cov nkoj no yog tsim los ntawm ib hom tshwj xeeb ntawm cov khoom siv ceramic uas tuaj yeem tiv taus qhov kub thiab txias ib puag ncig yam tsis muaj kev puas tsuaj loj lossis deformation.

Qhov zais cia tom qab qhov kev ua tau zoo tshwj xeeb ntawm BN sublimation nkoj nyob hauv cov khoom tshwj xeeb ntawm cov khoom siv boron nitride. BN yog ib qho binary compound ntawm boron thiab nitrogen, uas muaj cov qauv crystalline zoo ib yam li cov graphite. Nws muaj cov thermal thiab tshuaj stability, zoo heev hluav taws xob rwb thaiv tsev zog, thiab siab thermal conductivity, ua rau nws yog ib tug zoo tagnrho cov ntaub ntawv rau high-temperature daim ntaub ntawv.

Thaum BN sublimation tej nkoj nquam siv nyob rau hauv lub tshuab nqus tsev los yog inert gas ib puag ncig, cov khoom tsis hnov ​​​​mob nrog cov huab cua nyob ib puag ncig, xyuas kom meej purity thiab tiv thaiv kom txhob muaj kab mob. Tsis tas li ntawd, cov nkoj BN muaj cov coefficient tsawg ntawm thermal expansion, txhais tau tias lawv tuaj yeem tiv taus qhov kub thiab txias hloov sai yam tsis muaj kev tawg lossis tawg.

Kev tsim cov txheej txheem ntawm BN sublimation nkoj kuj tseem ceeb heev rau kev txiav txim siab lawv cov kev ua tau zoo. Thaum lub sij hawm tsim cov nkoj no, cov khoom siv boron nitride yog ua tib zoo molded rau hauv lub nkoj zoo, ces raug rho tawm ntawm qhov kub thiab txias kom nws lub zog thiab durability. Cov nkoj tom qab polished los xyuas kom meej ib tug du nto thiab tiv thaiv adhesion ntawm cov ntaub ntawv yuav tsum tau deposited.

Hauv kev xaus, cov lus zais tom qab qhov kev ua tau zoo tshwj xeeb ntawm BN sublimation nkoj nyob hauv cov khoom tshwj xeeb ntawm cov khoom siv boron nitride thiab cov txheej txheem tsim khoom zoo. Kev siv cov nkoj no nyob rau hauv cov ntawv thov kub tuaj yeem txhim kho qhov zoo thiab purity ntawm cov txheej txheem deposition thiab ua kom cov efficiency thiab nqi-zoo.

Shengyang New Material Co., Ltd. tau cog lus rau kev tsim cov boron nitride thiab boron nitride ua cov khoom, thiab tuaj yeem kho ntau yam boron nitride insulating ceramic qhov chaw raws li cov neeg siv khoom xav tau. Tiv tauj peb yog tias tsim nyog.
