Ceramics and Ceramic Substrates

Ceramics encompass such a vast array of materials that a concise definition is almost impossible.   Ceramic materials gives rise to many applications in chemical, electrical and mechanical engineering.

As ceramics are heat resistant, they can be used for many tasks  in a wide range of industries, offering many advantages compared to other materials. Ceramic materials tend to be strong, stiff, brittle, chemically inert, and non-conductors of electricity, but their properties vary widely which facilitates their use in many different product areas.  The ceramic raw materials  are both plentiful and inexpensive.

Ceramics can be divided into two classes: traditional ceramics and advanced ceramics.

Traditional ceramics include clay products, silicate glass and cement
Advanced ceramics consist of carbides (SiC), pure oxides (Al2O3), nitrides (Si3N4), non-silicate glasses and many others.

In general, advanced ceramics have the following inherent properties:

  •       Hard (wear resistant)
  •       Resistant to plastic deformation
  •       Resistant to high temperatures
  •       Good corrosion resistance
  •       Low thermal conductivity
  •       Low electrical conductivity

However, some ceramics exhibit high thermal conductivity, the combination of these properties means that ceramics can provide:

  •       High wear resistance with low density
  •       Wear resistance in corrosive environments
  •       Corrosion resistance at high temperatures
