Traditional ceramics include insulating materials glass refractories abrasives and enamels.
Properties of ceramics materials ppt.
Chemically inert they withstand chemical erosion that occurs in an acidic or caustic environment.

Properties of ceramic materials.
Advanced ceramics demand for advanced ceramics in the us is forecast to rise more than five percent annually to 13 5 billion in 2017.
Modern ceramics can be defined as the compounds of metals and non metals.
They include metal oxides carbides borides nitrides and silicates.
Mass properties e g density ceramics are intermediate density 2 00 6 00 gms cm3 different for allotropes e g glass cristobalite tridymite quartz 2.
Most ceramics are compounds between metallic and nonmetallic elements for which the interatomic bonds are either totally ionic bond or predominantly ionic but having same covalent character.
Ceramics play an important role in our day to day life.
Definition ceramic materials are inorganic non metallic materials and things made from them.
Melting points high 600 4000c thermal conductivities are low insulators thermal expansion values are low 1 15 ppm c 3.
Small component small σ.
Ceramic materials are brittle hard strong in compression durability weak in shearing and tension.
They fail if exposed to too fast temperature changes t t and locally to too large temperature gradients δt δx.
They generally have ionic atomic bonding between them.
Gains will be driven by the development of new applications for advanced ceramics and by their increased adoption in already established applications based on superior performance and material properties.
Technically ceramics are composed of raw materials such as powders and natural or synthetic chemical additives favoring either compaction hot cold orisostatic setting hydraulic or chemical oraccelerating sintering processes.
Ceramic materials are susceptible to thermal shock they fail if exposed to too fast temperature changes δt δt and locally to too what you already know and understand.
Generally they are inorganic and non metallic.
They may be crystalline or partly crystalline.
Properties of ceramics different properties of ceramic materials ceramics are oxides carbides nitrides borides of metal ions.
