Particle size determines the physical properties. It is important in structural and building materials. 23 5 strength and fracture surface energy of inorganic glasses. Glass is often not considered a ceramic because of its amorphous noncrystalline character.

A ceramic is a non metallic solid material comprising an inorganic compound of metal non metal and metalloid atoms primarily hold in ionic or covalent bonds. Generally strength and modulus go up and down together. Ceramics are generally brittle or ductile in nature. While maintaining the first edition s reputation for being an indispensable professional resource this new edition has been updated with sketches explanations figures tables summaries and problem sets to make it more student friendly as a textbook in undergraduate and graduate courses on the mechanical properties of ceramics.
