Nonmetallic crystal

Mechanical twins that form to reduce internal stress have also been observed in nonmetallic crystals. Mild reduction of vanadium pentoxide at low temperatures produces regions of reduced oxide that induce considerable shear stress in the matrix...

This chapter has covered the molecular structure of the high polymers which are the materials from which plastics are made. They are basically simple chemical entities which are connected chemically to form long chain molecules and in the case of thermosets, crosslinked from chain to chain. The structure of the polymeric materials has been compared to other types of materials such as metals, ceramics, amorphous materials such as glass, and nonmetallic crystals. 

Time-Dependent Density-Functional Theory to the Dielectric Function of Various Nonmetallic Crystals. 

Lattice vibrational energy transport, also known as phonon conduction, occurs in all solids—dielectrics and metals. In nonmetallic crystals and some intermetallic compounds, the principal mechanism of heat conduction is by...
