WebJun 5, 2012 · Ceramics are compounds consisting of metal and non-metal ions bonded either covalently or ionically. 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. WebThe crystalline solids are those in which the location of the molecules responds to a certain order that is repeated throughout the structure. Some crystalline solids are quartz, diamond and salt. The solid state is one in which the molecules of the material are in considerable proximity to one another.
