Ho ea ka maikutlo a batho, ceramic e senyeha habonolo.Leha ho le joalo, ka mor'a ts'ebetso ea theknoloji ea morao-rao, li-ceramics "li fetotsoe", ho fetoha ntho e ncha e thata, e matla haholo, haholo-holo tšimong ea lisebelisoa tse thibelang likulo tse nang le thepa e khethehileng ea 'mele, li-ceramics li khanya, li fetoha lisebelisoa tse ratoang haholo.
①Molao-motheo o thibelang likulo oa lisebelisoa tsa ceramic
Molao-motheo oa ts'ireletso ea lihlomo ke ho sebelisa matla a projectile, ho e liehisa, le ho etsa hore e se be kotsi.Lisebelisoa tse ngata tsa setso tsa boenjiniere, joalo ka lisebelisoa tsa tšepe, li monya matla ka ho senyeha ha polasetiki ea sebopeho, ha lisebelisoa tsa ceramic li monya matla ka ts'ebetso ea ho senya.
Mokhoa oa ho monya matla oa lirafshoa tse thibelang likulo o ka aroloa ka mekhahlelo e meraro:
(1) Mokhahlelo oa pele oa tšusumetso: Morero o ama bokaholimo ba ceramic, ho etsa hore hlooho ea ntoa e be lerootho le ho monya matla nakong ea ts'ebetso ea ho pshatla le ho etsa likhechana tse nyane le tse thata holim'a ceramic;
(2) Mokhahlelo oa khoholeho ea mobu: The projectile lerootho e tsoela pele ho senya sebaka se arohaneng, ho etsa lera le sa khaotseng la likhechana tsa ceramic;
(3) Mekhahlelo ea ho fetoha, ho phunyeha le ho robeha: Qetellong, khatello ea kelello e hlahisoa ka ceramic, e etsa hore e robehe.Ka mor'a moo, letlapa le ka morao lea senyeha, 'me matla ohle a setseng a kenngoa ke ho senyeha ha thepa ea morao.Nakong ea ts'ebetso ea ts'ebetso ea projectile ho li-ceramics, projectile le ceramics li senyehile.
②Litlhoko tsa thepa ea lirafshoa tse thibelang likulo
Ka lebaka la brittleness ea ceramic ka boeona, e robeha ha e anngoe ke projectile ho e-na le deformation ea polasetiki.Tlas'a ketso ea moroalo o tsitsitseng, ho robeha ho qala ho hlaha libakeng tse sa tšoaneng tse kang li-pores le meeli ea lijo-thollo.Ka hona, e le ho fokotsa khatello ea kelello ea microscopic, li-ceramics tsa lihlomo li lokela ho ba tsa boleng bo phahameng ka porosity e tlaase (ho fihlela ho 99% ea boleng ba theory) le sebopeho se setle sa lijo-thollo.

Thepa ea thepa le litlamorao tsa tsona mefuteng e thibelang likulo
Silicon carbide ceramic density e batla e le tlase, e thata haholo, ke lirafshoa tsa moralo tse theko e tlaase, ka hona hape ke lirafshoa tse thibelang likulo tse sebelisoang ka ho fetisisa China.
Li-ceramics tsa boron carbide li na le boima bo tlaase ka ho fetisisa le boima bo phahameng ka ho fetisisa har'a li-ceramics tsena, empa ka nako e ts'oanang, litlhoko tsa bona tsa theknoloji ea ho sebetsana le tsona li phahame haholo, tse hlokang mocheso o phahameng le khatello e phahameng ea khatello, kahoo litšenyehelo le tsona ke tse phahameng ka ho fetisisa har'a lirafshoa tsena tse tharo.
