why ceramic so hard?

Ceramics, are made by the direct method of heating at very hight temperatures and then rapidly cooling them. Due to this rapid quenching, they do not get enough time to form proper bonds and the bonds which were able to form in that time, become quiet hard due to the rapid processing. This, is a major factor which adds to the property of ceramics being hard and brittle. That is, they are not allowed to cool properly and form pearlites, but left at a stage of austenite and martensite mixture.
