Boron Carbide
Boron Carbide (B4C), tseem hu ua pob zeb diamond dub, nrog Vickers hardness ntawm> 30 GPa, yog qhov thib peb hardest khoom tom qab pob zeb diamond thiab cubic boron nitride. Boron carbide muaj qhov sib txawv siab rau kev nqus ntawm cov neutrons (xws li cov khoom tiv thaiv zoo tiv thaiv neutrons), ruaj khov rau ionizing hluav taws xob thiab feem ntau cov tshuaj. Nws yog cov khoom tsim nyog rau ntau daim ntawv thov kev ua haujlwm siab vim nws qhov kev sib xyaw ua ke zoo nkauj ntawm cov khoom. Nws zoo heev hardness ua rau nws haum abrasive hmoov rau lapping, polishing thiab dej dav hlau txiav ntawm hlau thiab ceramics.
Boron carbide yog cov khoom siv tseem ceeb nrog lub teeb yuag thiab lub zog zoo txhua yam. UrbanMines cov khoom muaj siab purity thiab cov nqi sib tw. Peb kuj muaj kev paub ntau hauv kev muab ntau yam ntawm B4C cov khoom. Cia siab tias peb tuaj yeem muab cov lus qhia muaj txiaj ntsig thiab muab kev nkag siab zoo rau koj ntawm boron carbide thiab nws cov kev siv ntau yam.
