Boron Carbide(B4C) e sebelisetsoa eng?
Bakeng sa boima ba eona:
Lintho tsa bohlokoa tsa Boron Carbide, tse khahlang moqapi kapa moenjineri, ke ho thatafala le ho hanyetsana ho amanang le abrasive. Mehlala e tloaelehileng ea tšebeliso e nepahetseng ea thepa ena e kenyelletsa: Liloko; Ho roala lihlomo tsa motho ka mong le tsa koloi; li-nozzles tse nang le grit; Li-nozzles tsa jete tsa metsi tse nang le khatello e phahameng; Ngola 'me u apare litlolo tse manganga; Lisebelisoa tsa ho itšeha le ho shoa; Li-abrasives; Metal matrix composite; Lirakeng tsa mariki tsa makoloi.

Boron carbide e sebelisoa ho etsa joalo ka Lihlomo tse Sireletsang ho hanela tšusumetso ea lintho tse bohale joalo ka likulo, shrapnel le metsu. Hangata e kopantsoe le metsoako e meng nakong ea ts'ebetso. Ka lebaka la boima ba eona bo phahameng, lihlomo tsa B4C li thata hore kulo e kenelle. Lintho tse bonahalang tsa B4C li ka monya matla a bullet ebe li qhala matla a joalo. Bokaholimo bo ne bo tla pshatleha hore e be likaroloana tse nyenyane le tse thata hamorao. Ho sebelisa thepa ea boron carbide, masole, litanka le lifofane ho ka qoba likotsi tse mpe tse tsoang likulo.
Bakeng sa thepa e 'ngoe:
Boron carbide ke sesebediswa sa taolo se sebediswang haholo dipolanteng tsa matla a nyutlelie bakeng sa bokgoni ba sona ba ho monya neutron, theko e tlase, le mohlodi o mongata. E na le karolo e kholo ea ho monya. Bokhoni ba boron carbide ho monya li-neutron ntle le ho etsa li-radionuclide tsa nako e telele li etsa hore e khahle joalo ka monyetla bakeng sa mahlaseli a nyutrone a hlahang lifemeng tsa matla a nyutlelie le ho tsoa ho libomo tsa anti-personnel neutron. Boron Carbide e sebedisetswa ho tshireletsa, jwalo ka lere la taolo sehlahiswang sa nyutlelie le jwalo ka ho kwala diphalete tsa polante ya matla a nyutlelie.
