WebCeramic processing generally involves high temperatures, and the resulting materials are heat resistant or refractory. Traditional ceramics refers to ceramic products that are … WebCeramic Bonding. Recall that the predominant bonding for ceramic materials is ionic bonding. In ionic bonding, a metal atom donates electrons and a nonmetal atom accepts electrons. This electron transfer creates positive metal ions (cations) and negative nonmetal ions (anions), which are attracted to each other through coulombic attraction.
