Yes crystalline yes free roaming valence electrons tied up in bonds. To protect metal structure from corrosion plastics are used as surface coatings. Crystal structure of ceramics ceramics contain the same imperfections in their crystal structure as metals vacancies displaced atoms interstitialcies and microscopic cracks internal flaws tend to concentrate stresses especially tensile bending or impact hence ceramics fail by brittle fracture much more readily than metals. Glass ceramics are made of small grains surrounded by a glassy phase and have properties in between those of glass and ceramics.

Form a single phase structure a phase any homogeneous mass of material such as a metal in which the grains all have the same crystal lattice structure in a solid solution the solvent or base element is metallic and the dissolved element can be either. Amorphous structure means that atoms are not organized according to a well ordered repeating arrangement as in crystals. Metals many ceramics some polymers atoms have no periodic packing occurs for.
