Hexagonal vs .} cubic boron nitride: kev sib txawv thiab thov kev nkag siab

Boron Nitride (BN), muaj ntawm Boron thiab Nitrogen, yog paub rau nws ntau yam kev lag luam thiab kev sib txawv ntawm kev siv thiab kev ua haujlwm zoo nkauj hauv kev teeb tsa thiab ua haujlwm .

1. kev sib txawv

Hexagonal Boron Nitride (H-BN):
H-BN muaj cov fawm kib, graphite-zoo li qauv nyob qhov twg boron thiab nexagonal at willers {2 {2 {2 {{4 4}}

Cubic Boron Nitride (C-Bn):
C-BN tau txais ib qho kev coj ua peb-seem ntawm pob zeb diamond, nrog cov qauv sib cav sib xyaw ua ke tsim los ntawm kev sib cav sib ceg, thib ob tsuas yog pob zeb diamond.

2. daim ntaub ntawv

H-Daim Ntawv Thov H-BN:

Kev Siv Roj Hmoo Kub

Hluav taws xob rwb thaiv tsev hauv cov khoom siv hluav taws xob

Cov tshuaj ntxiv hauv cov tshuaj pleev ib ce

Cov neeg sawv cev pwm thiab cov tsho tiv no

Kev tiv thaiv txheej txheem

C-BN Daim Ntawv Thov:

Kev Txiav Thiab Sib Tsoo Cov Cuab Yeej (Pob Zeb Diamond Hloov)

Hnav-resistant Cheebtsam

Samiconductor substrates rau high-fais fab cuab yeej

Qhov rai kho qhov rai thiab pob tshab ceramics

3.} kev sib raug zoo thiab kev hloov pauv

Txawm hais tias kev hloov pauv polymorphs zoo tshaj plaws rau kev hloov pauv ntawm pob zeb tawg rau hauv pob zeb diamond.

Hexagonal thiab Cubic Boron Nitride sawv cev rau ob qho kev sib txawv, txhua tus nrog cov khoom sib txawv ntawm cov khoom siv ua kom zoo dua qub thiab cov kev siv thev naus laus zis {4}
