Ho tloha lekholong la bo21 la lilemo, lirafshoa tse thibelang likulo li ntlafetse ka potlako ka mefuta e mengata, ho kenyeletsoa Alumina, Silicon Carbide, Boron carbide, Silicon Nitride, Titanium Boride, joalo-joalo. Har'a tsona, Alumina Ceramics (Al2O3), Silicon Carbide ceramics (SiC) le Boron Carbide Ceramics. (B4C) ke tsona tse sebelisoang haholo.
Li-ceramics tsa aluminium li na le boima bo phahameng ka ho fetisisa, empa boima bo batlang bo le tlase, tekanyo e tlaase ea ho sebetsa, le theko e tlaase.
Li-ceramics tsa silicon carbide li na le letsoalo le tlase haholo ebile li thata haholo 'me ke lirafshoa tsa moralo tse bolokang chelete e ngata, kahoo hape ke lirafshoa tse sa keneng likulo tse sebelisoang haholo Chaena.
Boron carbide ceramics ka mefuta ena ea ceramics e tlaase ka ho fetisisa, boima bo phahameng ka ho fetisisa, empa ka nako e ts'oanang litlhoko tsa ts'ebetso ea eona le tsona li phahame haholo, li hloka mocheso o phahameng le khatello e phahameng ea sintering, ka hona litšenyehelo le tsona ke tse phahameng ka ho fetisisa har'a tsena tse tharo. li-ceramics.
Ha ho bapisoa le lisebelisoa tsena tse tharo tse tloaelehileng tsa ceramic, theko ea Alumina ballistic ceramic e tlase ka ho fetesisa empa tšebetso ea ballistic e tlase haholo ho feta silicon carbide le boron carbide, kahoo phepelo ea hajoale ea ballistic ceramic hangata ke silicon carbide le boron carbide bulletproof.
Silicon carbide covalent bonding e matla haholo mme e ntse e na le maqhama a matla a phahameng mochesong o phahameng. Sebopeho sena se fana ka li-ceramics tsa silicon carbide matla a babatsehang, boima bo phahameng, ho hanyetsa ho roala, ho hanyetsa kutu, ho ba le mocheso o phahameng oa mocheso, ho hanyetsa mocheso o motle oa mocheso le lisebelisoa tse ling; ka nako e ts'oanang, li-ceramics tsa silicon carbide li theko e tlaase ebile li na le chelete e ngata, 'me ke e' ngoe ea lisebelisoa tsa ts'ireletso ea lihlomo tse ts'episang ka ho fetisisa. Li-ceramics tsa SiC li na le sebaka se pharaletseng sa nts'etsopele lefapheng la ts'ireletso ea lihlomo, 'me likopo li atisa ho fapana libakeng tse kang lisebelisoa tse nkehang habonolo le likoloi tse khethehileng. Joalo ka thepa e sirelletsang ea lihlomo, ha ho nahanoa ka lintlha tse joalo ka litšenyehelo le lits'ebetso tse ikhethileng, mela e menyane ea liphanele tsa ceramic hangata li tlamahanngoa le tšehetso e kopaneng ho theha lipoleiti tse reretsoeng ho hlola ho hloleha ha lirafshoa ka lebaka la khatello ea maikutlo le ho netefatsa hore sekotoana se le seng feela. e pshatloa ntle le ho senya lihlomo ka kakaretso ha projectile e phunyeletsa.
Boron carbide e tsejoa e le ntho ea boraro e thata ka ho fetisisa ka mor'a taemane le cubic boron nitride, e nang le boima ba ho fihla ho 3000 kg/mm2; tlaase-tlaase, feela 2,52 g/cm3, ; modulus e phahameng ea elasticity, 450 GPa; coefficient ea eona ea katoloso ea mocheso e tlase, 'me conductivity ea mocheso e phahame. Ho phaella moo, boron carbide e na le botsitso bo botle ba lik'hemik'hale, acid le alkali corrosion resistance; 'me ka boholo ba tšepe e qhibilihisitsoeng ha e kolobise ebile ha e kopane. Boron carbide e boetse e na le bokhoni bo botle ba ho monya neutron, bo sa fumaneheng lisebelisoa tse ling tsa ceramic. Boima ba B4C ke botlaaseng ba lirafshoa tse ngata tse sebelisoang hangata, 'me modulus ea eona e phahameng ea elasticity e etsa khetho e ntle bakeng sa lihlomo tsa sesole le lisebelisoa tsa lebala la sebaka. Mathata a ka sehloohong a B4C ke theko ea eona e phahameng le brittleness, e fokotsang tšebeliso ea eona e pharaletseng e le lihlomo tse sireletsang.
