Summary

​Ceramics, polymers and composites

In a nutshell

Ceramics and polymers are compounds. Composites are a mixture of compounds. 



Ceramics 

Ceramics are materials which are hard and brittle. They are made by baking a starting material in an oven that is extremely hot. they are stiff and insulators of heat and electricity.


Examples
  • Porcelain
  • Glass


​

Polymers

Polymers are long chains of repeating units known as monomers. Plastics are polymers. 


Properties

  • ​Generally, polymers are insulators of heat and electricity
  • Flexible
  • Malleable
  • Light


Examples
  • Nylon
  • PVC
  • Poly(ethene)


​

Composites

Forming a composite material consisting of a mixture of compounds can be useful as desired properties can be obtained.
