Ibhola le-ceramic elinamandla libizwa nangokuthi amabhola wokuhlunga. Kwenziwe ngokwenza ama-pores angama-20-30% ngaphakathi kwamabhola we-inert ceramic. Ngakho-ke ingasetshenziswa hhayi kuphela ukuxhasa nokumboza i-catalyst, kepha nokuhlunga nokususa ukungcola kokusanhlamvu, i-gelatin, i-asphalting, i-heavy metal ne-ayoni yensimbi engaphansi kuka-25um. Uma ibhola elinomhlwenga libekwe phezulu kwesiphenduli, ukungcola kwehluleka ukuqedwa kunqubo yangaphambilini kungakhangiswa kuma-pores angaphakathi kwamabhola, lapho lapho kuvikelwa khona okuvusayo futhi kwandise umjikelezo wokusebenza wohlelo. Njengoba ukungcola okukhona ezintweni zokusebenza kuhlukile, umsebenzisi angakhetha umkhiqizo ngosayizi wabo, ama-pores kanye ne-porosity, noma uma kunesidingo, engeza i-molybdenum, i-nickel ne-cobalt noma ezinye izinto ezisebenzayo ukuvimbela i-catalyst ekuphekeni noma ekufakeni ubuthi.
