B4C nanopowder Boron carbide hmoov rau vuam khoom
Product Description
Micropowder Dub B4C Boron Carbide Hmoov Rau Ceramic Txheej
Boron carbide, alias dub pob zeb diamond, feem ntau yog xim hmoov.Nws yog ib qho ntawm peb cov ntaub ntawv nyuaj tshaj plaws paub (lwm ob yog pob zeb diamond thiab cubic boron nitride) thiab siv rau hauv tank armour, mos mos mos thiab ntau yam kev siv.Nws yog siv rau hauv cov ntaub ntawv hnav-resistant, ceramic reinforced theem, tshwj xeeb tshaj yog nyob rau hauv lub teeb armor, reactor neutron absorbent, etc.
