Ceramic Materials,e electrons ceramics are poor conductors of electricity and heat. Lack of free electrons makes them also transparent to light. The ionic bonds are highly directional and stable; therefore they have relatively higher melting temperatures, on the average, than metals or polymers. Generally they are al

Structure-Property Relationships of Biological Materials,erials from artificial replacements. First, most biological materials are continuously bathed with a solution of water. Exceptions are the specialized surface layers of skin, hair, nails, hooves, and the enamel of teeth. Second, most biological materials can be considered as composites.

In addition, the massive nature of totally replacing such joints as the knee and elbow near the skin also renders the possibility of infection greater. More important, if the replacement fails for any reason it is harder to replace the joint a second time because a large po
