Ceramics are inorganic, non-metallic materials made from metal or non-metal compounds and hardened by heat. There are traditional ceramics derived from natural materials like clay and quartz, used to make tableware, bricks and tiles. Advanced ceramics have superior properties and include structural, electronic, and bio-ceramics. Ceramics are widely used in engineering applications due to their corrosion and heat resistance, used in automotive and jet engine components, electronic devices, cutting tools, and aerospace structures like rocket nozzles.

1. CERAMICS
INTRODUCTION AND ENGINEERING APPLICATIONS

2. INTRODUCTION
Ceramic is one of the oldest man-made materials around, and consists entirely
of naturally-occurring raw materials. Ceramic is 100% recyclable and can be added
as ground material to the production process or used in other industries as a
valuable raw material. The longevity and recyclability of materials is of critical
importance for our environment.
A ceramic is an inorganic non-metallic solid made up of either metal or non-
metal compounds that have been shaped and then hardened by heating to high
temperatures. In general, they are hard, corrosion-resistant and brittle.
Ceramic can divide into two parts.
1. Traditional Ceramics
2. Advance Ceramics

3. Traditional Ceramics
Traditional ceramics, ceramic materials that are derived from
common, naturally occurring raw materials such as clay minerals
and quartz sand. They mainly include kaolinite, whereas more
recent materials include aluminium oxide, more commonly
known as alumina.
Through industrial processes that have been practiced in
some form for centuries, these materials are made into such
familiar products as china tableware, clay brick and tile, industrial
abrasives and refractory linings, and Portland Cement.

4. ADVANCE CERAMICS
Advanced ceramics refer to many technical ceramics, which exhibit superior mechanical
and physical properties. These include superior corrosion/oxidation resistance, and thermal,
electrical, optical or magnetic properties. Advanced technical ceramics generally include
structural ceramics, electronic ceramics, ceramic coatings, and bio-ceramics.
The advanced technical ceramics era began approximately fifty years ago. These ceramics
are made using chemically prepared powders so that the chemical purity and important
physical properties can be controlled. Today, the market for advanced technical ceramics is
large and growing as they continue to replace more traditional materials like metals and
plastics in many applications while providing the only material solution in some specific and
strategic applications.
