What are ceramics? Ceramics are elements composed of at least two elements, often more, with complex crystal structures that range from purely ionic to totally covalent. Anisotropy directionality of properties What influences the crystal structure of ceramics? The electrical charge of ions and the relative sizes of the anion and cation. Why must a ceramic molecule be neutral? The net charge across the cation and anion must be 0, and the whole ceramic molecule must be neutral. ...
