Most ceramics are crystalline. They tend to have high melting points and be very hard and brittle. Their tensile strengths are limited by brittle fracture but their compressive strengths are high.
WebMaterials, capabilities, and limitations. Extrusion of thermoplastics is best done with amorphous materials, notably PVC, PS, LDPE, ABS, and thermoplastic rubbers, such as EPDM. Semi-crystalline plastics (e.g., PP, HDPE) can also be extruded, but their more pronounced shrinkage is a problem. In this respect, the process is comparable to ...

All piezoelectric classes lack inversion symmetry. Any material develops a dielectric polarization when an electric field is applied, but a substance that has such a natural charge separation even in the absence of a field is called a polar material. Whether or not a material is polar is determined solely by its crystal structure.
