Nano boron phofo ke karolo e tukang e matla haholo.The volumetric calorific value (140kg/cm3) le mass calorific value (59kg/g) ea elemental boron e kholo haholo ho feta ea lisebelisoa tse ling tse matla tsa molek'hule tse kang magnesium le aluminium.
'Me phofo ea boron ke mafura a matle, haholo-holo nano boron phofo e na le ts'ebetso e phahameng ea ho tuka, kahoo ho eketsa nano boron phofo ho liqhomane kapa li-propellants ho ka eketsa matla a matla a lisebelisoa tse matla.
Phofo ea boron e na le boleng bo phahameng ba k'halori le boleng ba k'halori, 'me ke mafura a tšepe a nang le menyetla e metle ea ts'ebeliso, haholo-holo tšimong ea li-propellants tse thata tse futsanehileng.Hajoale ke eona feela ramjet e tiileng e ka fihlelang tšusumetso e itseng ea 10kN·s.Matla a propulsion ka holimo ho kg-1, kahoo boron ke e 'ngoe ea mafura a loketseng ka ho fetisisa ho li-propellants tse nang le oksijene.
E le ho ntlafatsa mosebetsi oa phofo ea boron, B / X (X = Mg, Al, Fe, Mo, Ni) likaroloana tse kopantsoeng li boetse li lokiselitsoe ho sebelisoa ho li-propellants.
Boemo ba polokelo:
Boron Powder e lokela ho kwalwa mme e bolokwe sebakeng se ommeng, se phodileng.Ha ea lokela ho pepeseha moeeng ka nako e telele ho thibela agglomeration ka lebaka la mongobo, e leng se tla ama ts'ebetso ea ho hasana le phello ea tšebeliso.Ho phaella moo, qoba khatello e boima 'me u qobe ho kopana le li-oxidants.
