Boron Nitride Block

Boron nitride ceramics yog ua los ntawm boron nitride hmoov tom qab raug nias thiab sintered rau hauv boron nitride blocks ntawm qhov kub thiab txias thiab tom qab ntawd ua tiav raws li qhov loj me thiab cov lus qhia tshwj xeeb los ntawm cov neeg siv khoom.

Cov qauv ntawm boron nitride zoo ib yam li cov graphite, teej tug mus rau daim ntawv hexagonal qauv, tseem hu ua dawb graphite. Boron nitride muaj hluav taws xob rwb thaiv tsev zoo, thermal conductivity, zoo heev thermal shock kuj thiab tshuaj stability, zoo noo noo tsis kam rau molten hlau, slag, thiab iav.

Boron nitride ceramics muaj qhov kub thiab txias tsis kam, thiab yuav tsis hloov ntawm 2100 ° C nyob rau hauv kev tiv thaiv ntawm inert gas xws li nitrogen thiab 1800 ° C nyob rau hauv ib qho chaw nqus tsev vacuum. Tsis tas li ntawd, boron nitride muaj zog tshuaj stability. Boron nitride ceramics tsis hnov ​​​​mob rau feem ntau cov hlau, ceramics, tsawg lub ntiaj teb, thiab lwm yam ntaub ntawv, thiab tsis txhob ua raws li.

Daim ntawv thov kev lag luam ntawm boron nitride ceramics: high-temperature hluav taws xob rauv qhov chaw (high-temperature rwb thaiv tsev lub tes tsho, thiab lwm yam), hlau evaporation crucible, molten hlau los yog iav nrog ntau yam khoom siv, hlau zoo nkauj lossis tshwj xeeb alloy casting pwm qhov chaw, siab- Kev them nyiaj yug kub, thiab lwm yam kev ntxhov siab, molten hlau thauj yeeb nkab, nozzle, thiab lwm yam.

Mohs hardness ntawm boron nitride ceramics yog tsawg heev, thiab cov khoom yog lub teeb, mos, thiab yooj yim rau txheej txheem. Lub boron nitride block muaj kev ua haujlwm zoo thiab tuaj yeem ua tiav rau ntau qhov chaw raws li cov neeg siv khoom xav tau. (raws li cov duab hauv qab no qhia)
