Ceramics are made of inorganic and nonmetallic solids (nonmetallic compounds). In an ionic bond, one of the atoms (the metal) transfers electrons to the other atom (the nonmetal), thus becoming positively charged (cation), whereas the nonmetal becomes negatively charged (anion). Compared with glass or resin optical materials, transparent ceramics are stronger, harder, more resistant to corrosion and high temperature, and can be used in extremely severe conditions. An important aspect here is how to transform the ceramic particles into a desired shape.
