Chipepala choteteza zipolopolo cha ceramic (mbale yoteteza zipolopolo)ndi gawo lofunika kwambiri pa zida zoteteza zipolopolo. Pakadali pano, zipolopolo za silicon carbide ndi zipolopolo za alumina zapamwamba ndi zinthu ziwiri zofunika kwambiri pamsika. Chifukwa chakuti njira yoteteza zipolopolo imachitika nthawi yochepa kwambiri, zipolopolo za ceramic zimafuna zinthu zambiri, monga kuchulukana, kupendekera, kuuma, kulimba kwa kusweka, elastic modulus, liwiro la mawu ndi mphamvu yamakina, ndi zina zotero.
Chipepala cha alumina cha ceramic cha Chemshun chimapangidwa ndi ufa wa alumina wabwino kwambiri ngati chinthu chachikulu. Kuyera kwa α-Al₂O₃ kumaposa 99%, kuchuluka kwake ndi ≥3.9g/cm³, kuchuluka kwake kuli pafupi ndi zero, ndipo kuchuluka kwa madzi sikuposa 0.02%. Kuuma kwake kumatha kufika pamwamba pa HRA88, chomwe ndi chinthu choyamba kusankha pa zinthu zoteteza zipolopolo. Kuchuluka kwa zipolopolo kumaposa mlingo wa American standard 3. Nthawi yomweyo, kumakwaniritsa zosowa za makasitomala pa zinthu zoteteza zipolopolo za silicon carbide. Kuchuluka kwake ndi ≥3.1g/cm³, kuuma kwake ndi ≥HRA92, ndipo kuchuluka kwa zipolopolo kumatha kufika ku American Standard 4.
Kukula kwa pepala la alumina losalowa zipolopolo la chemshun ndi 50*50*10mm ndi 50*25*10mm, ndipo kukula kokhazikika kwa silicon carbide ceramic ndi 250*300mm. Makasitomala ali ndi zofunikira zina ndipo amatha kuvomereza kusintha.
