B4C nanopowder Boron carbide hmoov rau vuam khoom
Product Description
Boron carbide yog ib yam khoom tsis muaj zog, feem ntau yog hmoov grey-dub.Nws muaj qhov ntom ntom (2.55g / cm³), qhov siab melting point (2350 ° C), thiab zoo heev tshuaj lom neeg stability thiab neutron absorption.Cov khoom yog ib qho nyuaj heev, sib npaug ntawm hardness ntawm pob zeb diamond, thiab muaj cov khoom ntawm neutron absorber.Qhov no tau coj mus rau kev siv boron carbide hauv ntau qhov chaw, xws li lub zog nuclear ua lub tshuab nqus tsev nqus, nrog rau cov khoom siv resistant, ceramic reinforcement theem, hnav armor, thiab tshwj xeeb tshaj yog nuclear reactor neutron absorber.
