Grade And Classification Of Ceramics

Ceramics can be classified into two main categories based on their properties: traditional ceramics and advanced ceramics.

Traditional ceramics are typically made from clay and other natural raw materials and are fired at high temperatures. They are classified based on their composition and properties, as well as the temperature at which they are fired. Traditional ceramics include:

1. Earthenware – fired at low temperatures (below 1200°C), usually porous and not suitable for holding liquids

2. Stoneware – fired at higher temperatures (1200-1300°C), non-porous and more durable than earthenware

3. Porcelain – fired at the highest temperatures (above 1300°C), non-porous and translucent

Advanced ceramics, on the other hand, are made from synthetic materials and are designed to possess superior mechanical, thermal, electrical, and chemical properties. They are classified based on their applications, such as structural ceramics, functional ceramics, and bioceramics. Some examples of advanced ceramics include:

1. Structural ceramics – used in aerospace, automotive, and medical industries due to their strength and durability

2. Functional ceramics – used in electronic, optical, and magnetic applications due to their unique properties

3. Bioceramics – used in medical implants and prosthetics due to their biocompatibility and ability to integrate with living tissue.
