M'mafakitale komwe kutumiza zinthu zonyamulika kumagwira ntchito tsiku ndi tsiku, kulephera kwa mapaipi msanga sikungokhala vuto lokonza zinthu—koma ndi vuto lalikulu. Mapaipi athu a alumina oyeretsedwa kwambiri komanso osawonongeka amapangidwa kuti athetse vutoli. Ndi kuchuluka kwa alumina (Al₂O₃) kopitilira 95%, mapaipi awa ali ndi kuuma kwa Rockwell kwa HRA 85-90, komwe kuli kwachiwiri pambuyo pa diamondi. Kuuma kwakukulu kumeneku kumatanthauza kukana kwambiri kugwedezeka ndi kugwedezeka kwa tinthu tating'onoting'ono, zomwe zimapangitsa kuti moyo wa ntchito ukhale wosavuta nthawi 5 mpaka 10 poyerekeza ndi mapaipi achitsulo cholimba. Chofunika kwambiri, kuuma kwakukulu kumeneku kumafanana ndi kuchuluka kochepa kwa pafupifupi 3.6 g/cm³, zomwe zimapangitsa kuti mapaipi a ceramic akhale opepuka kwambiri kuposa njira zina zachitsulo, motero amachepetsa katundu womangidwa ndi ndalama zoyikira popanda kuwononga kulimba.
Njira yopangira yapamwamba ndi yofunika kwambiri pakugwira bwino ntchito kwa chitoliro. Chingwe chilichonse chimapangidwa kudzera mu njira yopondereza kapena yotulutsa mpweya wopanikizika kwambiri, kutsatiridwa ndi kuyatsa molondola mu uvuni wotentha kwambiri pa 1500°C–1700°C. Kupopera kolamulidwa kumeneku kumapanga kapangidwe kakang'ono kolimba, kofanana komanso kopanda ma porosity ambiri, zomwe zimapangitsa kuti ma ceramic liners azigwira ntchito bwino pogwiritsa ntchito epoxy resin yapadera yolimba komanso yosatentha. Kapangidwe kameneka kamagwiritsa ntchito kuuma kwa ceramic kuti isawonongeke komanso kulimba kwa chitsulo kuti chiteteze makina, kuonetsetsa kuti chikugwira ntchito bwino pansi pa kutentha kwambiri komanso kugwedezeka kwambiri. Pamwamba pa mapaipi athu a ceramic kumakhala kosalala ndi kuuma kwathunthu (Ra value) kosakwana 0.4 μm, chinthu chofunikira chomwe chimachepetsa kukana kukangana, chimalimbikitsa kuyenda kwa laminar, komanso chimachepetsa kwambiri kutsekeka kwa zinthu, zomwe zimapangitsa kuti mapaipi awa akhale ofunikira kwambiri pamakina oyendera mpweya ndi madzi.
Kugwiritsa ntchito mapaipi athu a alumina ceramic m'dziko lenileni kumaphatikizapo zinthu zambiri zomwe zimawonongeka kwambiri. M'mafakitale opanga magetsi opangidwa ndi malasha, ndi omwe amasankhidwa bwino kwambiri pa mizere ya PCI yophwanyidwa ndi phulusa louluka, zomwe nthawi zambiri zimakhala zopambana basalt ndi chitsulo cholimba kwambiri. Gawo la migodi ndi kukonza mchere limadalira iwo ponyamula matope okhuthala monga chitsulo chosungunuka, mkuwa, ndi mchenga wa silica, komwe kukana kwa chitoliro ku kuwonongeka ndi dzimbiri la mankhwala kuchokera ku matope a acidic kapena alkaline ndikofunikira kwambiri. Kuphatikiza apo, m'mafakitale a simenti, zitsulo, ndi feteleza wa mankhwala, mapaipi awa amatsimikizira kuti ntchito ikuyenda bwino m'malo ovuta omwe amakhudzidwa ndi tinthu tating'onoting'ono tambirimbiri. Pomaliza, kuyika ndalama m'mapaipi athu a alumina ceramic ndi chisankho chanzeru - kusintha kukonza kosinthika ndi kudalirika kogwira ntchito, kuchepetsa kwambiri nthawi yopuma yosakonzekera, ndikupereka mtengo wotsika wa umwini pa moyo wonse wa katundu.
