Boron carbide
Boron Carbide (B4C), tseem hu ua lub pob zeb diamond dub, nrog cov khoom tawv tawv ntawm> 30 GPA, yog qhov khoom tshaj plaws tom qab pob zeb diamond thiab cubic nitride. Boron Carbide muaj cov pej xeem siab rau kev nqus ntawm neutrons (piv txwv li cov kev tiv thaiv zoo rau kev tawm tsam neionroning hluav taws xob thiab cov tshuaj feem ntau. Nws yog cov khoom haum uas tsim nyog rau ntau cov ntawv thov kev ua tau zoo vim nws cov khoom siv ntxim nyiam ntawm cov khoom. Nws cov zoo tshaj plaws hardness ua rau nws lub hmoov av uas tsis haum rau lapping, polishing thiab dej thiab dej dav hlau txiav cov hlau thiab ceramics.
Boron carbide yog ib qho tseem ceeb nrog lub teeb yuag thiab zoo heev zog. Urbanmines 'cov khoom muaj cov nqi siab thiab kev sib tw. Peb kuj muaj ntau txoj kev paub hauv kev muab ntau ntawm B4C cov khoom lag luam. Vam tias peb tuaj yeem muab lus qhia pab tswv yim thiab muab kev nkag siab zoo ntawm Boron carbide thiab nws ntau yam kev siv.
