Iyoalumina ceramic rabha liner isingapfekichinhu chakasanganiswa chinoshandiswa zvakanyanya mukuchengetedza kupfeka kwemaindasitiri. Chinowedzera hupenyu hwemidziyo mumamiriro ezvinhu akaoma nekubatanidza kuramba kupfeka kwakanyanya kwealumina ceramic nehunhu hwerabha hwekunamira. Chishandiso ichi chinoshandisa alumina sechinhu chikuru, nekuwedzera ceramic powder nesilicon oxide, zvakanyungudutswa pakupisa kwakanyanya kunosvika 1700°C. Kuwanda kwealumina kwacho kazhinji hakusi pasi pe95%, huwandu hwesimbi hunosvika 3.5-3.9 g/cm³, uye kuomarara kweRockwell kwakakwira seHRA85-90, zvichiita kuti isapfekwe zvakanaka. Mukushandiswa kwakakodzera, chishandiso ichi chinoratidza chimiro chakasanganiswa che multi-layer: chikamu chepamusoro ialumina ceramic, chikamu chepakati irabha, uye pasi iplate yesimbi inotsigira. Aya matatu matinji akabatanidzwa zvakasimba kuburikidza ne vulcanization process, zvichigadzira sisitimu yekudzivirira kupfeka yakabatana.
Kushanda kwakanaka kwemuchina uyu wekubatanidza kunoratidzwa muzvinhu zvakawanda: Chekutanga, kuramba kwawo kupfeka kwakanaka kwazvo, nekuomarara kwealumina corundum ceramic kuchisvika pamusoro peHRA85, uye kuramba kwekupfeka kuri kanopfuura mazana maviri pane simbi yakajairwa yekabhoni. Chechipiri, chigadzirwa ichi chine kuramba kwakanaka kwekukanganisa. Kuburikidza nefomura yeceramic yakasimba uye dhizaini yakasarudzika yedenderedzwa, pamwe chete nerubha buffer layer, inogona kudzivirira kukanganiswa nezvinhu zvakakura. Chechitatu, muchina uyu unodzivirira kupisa zvakanaka uye unogona kushanda zvakadzikama mukati mekupisa kwe0°C kusvika 250°C kwenguva yakareba. Pamusoro pezvo, muchina werabha unoshandisa fomura yakakosha ine kuramba kweasidhi nealkali, inokwanisa kumira ngura munzvimbo dzisina acid nealkali dzisina simba. Kana tichitarisa zvinhu zviri mukati, simba rekudzvanya remuchina uyu i ≥850 MPa, kuomarara kwemuchina uyu i KΙC ≥4.8 MPa·m1/2, simba rekubatanidza rabha neceramic (shear stress) ≥3.0 MPa, uye hupenyu hwekukwegura kwerabha i ≥makore gumi nemashanu, zvichiita kuti chigadzirwa chirambe chakavimbika kwenguva refu.
Mapurasitiki erabha ealumina ceramic anodzivirira kupfeka anoshandiswa zvakanyanya muminda yemaindasitiri, kunyanya anosanganisira masisitimu ekufambisa marasha ane simba remoto, mahopper esimbi, machute emugodhi, michina yekuwachisa marasha, masisitimu ekufambisa simende, nedzimwe nzvimbo dzakasakara zvakanyanya. Mukushandiswa kwazvino, mapurasitiki anowanzo kamurwa kuita mhando dzakasiyana dzakadai semabhondi, akasungirirwa, uye rabha composite, kusanganisira zvakasiyana-siyana zvakaita serectangle yakasimba, ine maburi akatenderera, uye mapaipi etrapezoidal. Anogona kuchekwa nekukotamiswa zvichienderana nechimiro chemidziyo, zvichizadzisa zvinodiwa zvekuisa michina ine chimiro chakasarudzika. Dhizaini yemodular inoita kuti kuiswa nekutsiviwa kuve nyore, zvichideredza zvakanyanya nguva yekugadzirisa michina nemitengo. Mupurojekiti yekuchinja tekinoroji yekuchera nekugadzira hunyanzvi hwegirini ye4.5 miriyoni matani eDundee Mining, bhini rekugaya rakatora mapuranga eceramic emhando yepamusoro ane K95 fine alumina content ≥95% uye density ≥3.8 g/cm³, zvichiratidza kuvimbika kwayo mumapurojekiti makuru emaindasitiri.
