4. Mechanical Strength

Txawm hais tias yog cov khoom siv ceramic, boron nitride wafers pom muaj zog thiab ua haujlwm ntev. Lawv tuaj yeem tiv taus kev kub ntxhov thiab kev ntxhov siab, ua rau lawv tsim nyog rau kev siv hauv kev thov kev thov uas yuav tsum muaj kev ua haujlwm zoo.

Kev tsim khoom

Cov txheej txheem tsim khoom ntawm boron nitride wafers suav nrog cov txheej txheem siab heev kom ua tiav cov khoom xav tau thiab zoo. Qee txoj hauv kev muaj xws li:

1. Chemical Vapor Deposition (CVD)

CVD yog cov txheej txheem siv dav rau kev loj hlob zoo boron nitride films ntawm substrates. Nyob rau hauv cov txheej txheem no, precursors uas muaj boron thiab nitrogen yog nkag mus rau hauv lub chamber, qhov uas lawv hnov mob los ua ib tug nyias zaj duab xis ntawm boron nitride nyob rau hauv substrate nto. CVD muaj kev tswj xyuas meej txog cov yeeb yaj kiab tuab thiab sib xws, ua rau nws tsim nyog rau kev tsim khoom loj.

2. Kub nias

Kub-nias muaj xws li compressing boron nitride hmoov ntawm qhov kub thiab txias los tsim cov wafers tuab. Txoj kev no yog qhov tshwj xeeb tshaj yog rau kev tsim cov khoom siv boron nitride nrog siab purity thiab mechanical zog.
