Mpira wambiri wa ceramic umatchedwanso kuti kusefa mipira. Zimapangidwa ndi kupanga 20-30% pores mkati mwa mipira ya ceramic. Chifukwa chake itha kugwiritsidwa ntchito osati kungothandizira ndikuphimba chothandizira, komanso kusefa ndikuchotsa zosafunika za tirigu, gelatin, asphalting, heavy metal ndi iron ayoni osakwana 25um. Ngati mpira wa porous wakhazikika pamwamba pa riyakitala, zosavomerezeka zikalephera kuthetsedwa kale zimatha kulengezedwa m'matumba amkati mwa mipira, pamenepo poteteza chothandizira ndikuchulukitsa kuzungulira kwa magwiridwe antchito. Popeza zonyansa zomwe zilipo pazinthuzi ndizosiyana, wogwiritsa ntchito amatha kusankha malondawo ndi kukula kwawo, pores ndi porosity, kapena ngati kuli kotheka, onjezerani molybdenum, nickel ndi cobalt kapena zinthu zina zoteteza kuti chothandizira chisatseke kapena kupha poizoni.
