Nkọwa:
Nano boron ntụ ntụ bụ ihe na-eme ka ọkụ dị elu.Uru calorific volumetric (140kg/cm3) na uru calorific (59kg/g) nke boron elemental dị nnọọ ukwuu karịa nke ihe ndị ọzọ na-enye ume otu molecule dị ka magnesium na aluminom.
Na boron ntụ ntụ bụ ezigbo mmanụ ọkụ, karịsịa nano boron ntụ ntụ nwere ọrụ ọkụ ọkụ dị elu, ya mere ịtinye nano boron ntụ ntụ na ihe mgbawa ma ọ bụ ihe ndị na-emepụta ihe nwere ike ịbawanye ike nke usoro ihe ike.
Boron ntụ ntụ nwere nnukwu uru calorific dị elu na uru calorific, ọ bụkwa mmanụ ígwè nwere atụmanya ngwa dị mma, karịsịa n'ọhịa nke ikuku oxygen-ogbenye siri ike.Ọ bụ ugbu a naanị ramjet siri ike nke nwere ike nweta mkpali akọwapụtara nke 10kN·s.Ike na-ebuli elu karịa kg-1, ya mere boron bụ otu n'ime mmanụ ọkụ kachasị mma na ikuku oxygen na-adabere na ya.
Iji mee ka ọrụ nke boron ntụ ntụ dịkwuo mma, B / X (X = Mg, Al, Fe, Mo, Ni) a na-akwadokwa ihe ndị na-emepụta ihe na-emepụta ihe.
