Ngwa ndị bụ isi nke boron carbide bụ ndị a:
1.Ngwa nke polishing abrasive
Ngwa nke boron carbide dị ka abrasive bụ tumadi polishing nke sapphire.N'ihe ndị siri ike, ike nke boron carbide dị elu karịa nkealuminum oxidena silicon carbide, naanị dị ala karịa diamond na cubic boron nitride.Boron carbide abrasive (Mohs hardness 9.3) bụ ihe kachasị mma maka nhazi na igwe kristal sapphire.Mgbe boron carbide dị n'elu 600 ℃, elu ya ga-abụ oxidized n'ime ihe nkiri B2O3, nke ga-eme ka ọ dị nro ruo n'ókè ụfọdụ.Ya mere, ọ dịghị adabara akọrọ akọrọ na oke okpomọkụ na ngwa abrasive, ma ọ bụ naanị maka polishing mmiri mmiri egweri.Otú ọ dị, ihe onwunwe a nwere ike igbochi oxidation ọzọ nke B4C, nke na-eme ka ọ nwee uru pụrụ iche na ngwa refractory.
2.Ngwa nke ihe ndị na-emegharị ihe
Boron carbide nwere njirimara nke nguzogide oxidation na oke okpomọkụ na-eguzogide.A na-ejikarị ya eme ihe dị ka ihe ndị na-emepe emepe na amorphous refractories dị iche iche dị iche iche nke metallurgy, dị ka ígwè stovu, kiln ngwá ụlọ, wdg Boron carbide ga nro na elu okpomọkụ, n'ihi ya, ọ nwere ike rube isi na elu nke ndị ọzọ ihe ahụ irighiri.Ọbụlagodi na ngwaahịa ahụ nwere densified, ihe nkiri B2O3 oxide dị n'elu ya nwere ike mepụta ogo ụfọdụ nke nchebe ma rụọ ọrụ mgbochi oxidation.N'otu oge ahụ, n'ihi na kristal kọlụm nke mmeghachi omume na-ekesa na-ekesa na matrix na ọdịiche nke refractory, porosity na-ebelata, ike okpomọkụ nke ọkara na-eme ka ọ dịkwuo mma, na mgbasawanye olu nke kristal ndị a na-emepụta nwere ike ịgwọ mbelata olu na belata mgbawa.
3.Ngwa nke ihe mgbochi mgbọ
N'ihi ike siri ike ya dị elu, ike dị elu, obere ike ndọda na nkwụsi ike dị elu, boron carbide dabara na usoro nke ihe mgbochi mgbọ dị arọ, ọ bụkwa ihe kachasị mma maka ụgbọ elu, ụgbọ ala, ngwa agha, ahụ mmadụ na nchebe ndị ọzọ.
4.Ngwa na ụlọ ọrụ nuklia
Carbide boron nwere akụkụ obe nke neutron dị elu yana ụdị nnabata neutron dị obosara, nke a na-amata n'ụwa niile dị ka ihe kacha mma neutron na ụlọ ọrụ nuklia.Boron carbide nwere akụ bara ụba, nguzogide corrosion, ezigbo nkwụsi ike nke okpomọkụ, enweghị isotopes redioaktivu, ike ọkụ dị ala nke abụọ, wdg, yabụ a na-eji ya eme ihe dị ka ihe njikwa na ihe mkpuchi na ihe nrụpụta nuklia.A ga-eme boron carbide ka ọ bụrụ mkpanaka boron carbide n'ime mpaghara ihe nrụpụta nuklia, a ga-emekwa ya ka ọ bụrụ boron carbide ntụ ntụ n'ihi mkpa ọ dị ịbawanye elu.
