Boron Carbide
Boron Carbide (B4C), tseem hu ua pob zeb diamond dub, nrog Vickers hardness ntawm >30 GPa, yog cov khoom siv thib peb nyuaj tshaj plaws tom qab pob zeb diamond thiab cubic boron nitride. Boron carbide muaj qhov seem siab rau kev nqus cov neutrons (piv txwv li cov khoom tiv thaiv zoo tiv thaiv neutrons), ruaj khov rau cov hluav taws xob ionizing thiab feem ntau cov tshuaj lom neeg. Nws yog cov khoom siv tsim nyog rau ntau daim ntawv thov kev ua haujlwm siab vim nws cov khoom sib xyaw ua ke zoo nkauj. Nws qhov nyuaj ua rau nws yog cov hmoov abrasive tsim nyog rau lapping, polishing thiab dej dav hlau txiav ntawm cov hlau thiab ceramics.
Boron carbide yog ib yam khoom tseem ceeb uas muaj lub cev nyhav me me thiab muaj zog heev. Cov khoom UrbanMines muaj cov khoom huv si thiab cov nqi sib tw. Peb kuj muaj ntau yam kev paub hauv kev muab ntau yam khoom B4C. Vam tias peb tuaj yeem muab cov lus qhia pab tau thiab muab kev nkag siab zoo dua rau koj txog boron carbide thiab nws cov kev siv ntau yam.
