The99% alumina e loantšang bolo ea letsopake ceramic ea boenjiniere e sebetsang hantle e nang le α-alumina (α-Al2O₃) e le karolo ea mantlha ea kristale le karolo ea alumina e fetang 98%. E na le boemo bo boholo tšireletsong ea lihlomo tsa botho le tsa koloi ka lebaka la boima ba eona bo phahameng, boima bo itekanetseng, ho hanyetsa ho tsofala ho hoholo, le karolelano e ntle ea litšenyehelo le ts'ebetso. Mokhoa oa eona oa tšireletso o itšetlehile haholo-holo ka thata ea eona e phahameng le modulus ho fifatsa le ho arola projectile e kenang, ha e ntse e monya le ho qhala boholo ba matla a kinetic a projectile ka ts'ebetso ea eona ea ho robeha. Matla a setseng ebe a monngoa ke thepa e kopantsoeng e tšehetsang (mohlala, polyethylene e boima ba limolek'hule kapa lesela le le leng). Litšobotsi tsa bohlokoa tsa 'mele li kenyelletsa boima ba bongata bo seng ka tlase ho 3.9 g/cm³, boima ba Mohs ba 9, matla a ho kheloha ho fihlela ho 580 MPa, hammoho le ho monngoa ha metsi a tlase (<0.006%) le botsitso bo botle ba mocheso.
Ts'ebetso ea tlhahiso e qala ka khetho ea phofo ea alumina e hloekileng haholo, e ntle haholo, hangata e nang le boholo ba likaroloana tsa submicron (D50 e ka bang 0.35 ~ 1.4 μm). Mekhoa ea mantlha ea ho theha e kenyelletsa ho hatella ka omileng le ho hatella ka isostatic, ho lateloa ke ho tenyetseha ka ho sintering ea sepakapaka kapa ho hatella ka ho chesa. Ho hlōla ho tetebela ha tlhaho ha ceramic le ho ntlafatsa khanyetso ea ho otla ka makhetlo a mangata, lipatlisiso tsa pele li shebana le mahlale a ho tiisa, joalo ka ho hlahisa litelu tsa silicon carbide kapa zirconia ho theha li-ceramic tse kopaneng tsa alumina matrix. Lisebelisoa tsena tse kopaneng li ka sitisa ho ata ha mapetso ka katleho boemong ba microstructural, tsa ntlafatsa haholo ho tiea, ho hanyetsa tšusumetso, le ts'ebetso e akaretsang ea ballistic.
Litšebelisong tse sebetsang, 99% ea liseramike tsa alumina hangata li etsoa ka lithaele tse bōpehileng joaloka kamehla (likwere, likhutlonnetsepa, liheksagone) kapa likotoana tse kobehileng tse bōpehileng joaloka tse khethehileng ho kopanya lipoleiti tse entsoeng ka ballistic tse ergonomic. Lipoleiti tse thata tsa tšireletso tse entsoeng ka thepa ena li fetile liteko tsa profeshenale tsa ballistic tse kang NIJ Standard-0101.06 Level III le IV. Lithuto tsa liteko li bontšitse hore ho eketsa ho koalloa lipoleiting tsa ceramic ho ka ntlafatsa ho hanyetsa ha tsona ho kenella. Ka lebaka la ts'ebetso ea eona e ikhethang ea ho thibela likulo, boima bo tlase le litšenyehelo tsa tlholisano, 99% ea alumina e thibelang likulo e fetohile thepa e hlahelletseng 'marakeng oa lipoleiti tse thibelang likulo tsa ceramic.
