Ceramic Bonding MATSE 81: Materials In Today's World

Ceramic Bonding. Print. 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.

Covalent bonding instead occurs between two nonmetals, in other words two atoms that have similar electronegativity, and involves the sharing of electron pairs between the two atoms. Although both types of bonds occur between atoms in ceramic materials, in most of them (particularly the oxides) the ionic bond is predominant.

Advanced ceramics - Advanced ceramics - Chemical bonding: Reaction sintering, or reaction bonding, is an important means of producing dense covalent ceramics. Reaction-bonded silicon nitride (RBSN) is made from finely divided silicon powders that are formed to shape and subsequently reacted in a mixed nitrogen/hydrogen or nitrogen/helium atmosphere at 1,200 to 1,250 °C (2,200 to 2,300 °F).

Ceramic property - University of Washington

The properties of ceramic materials, like all materials, are dictated by the types of atoms present, the types of bonding between the atoms, and the way the atoms are packed together. This is known as the atomic scale structure. Most ceramics are made up of two or more elements. This is called a compound.
