A
ceramic is an inorganic solid material, made up of either metal or non-metal
compound. Traditionally ceramics were shaped and then hardened by heating to
high temperatures. In general, they are hard, corrosion-resistant and brittle
material.
What are Traditional ceramics?
The Traditional ceramics can be categorized as porcelain,
earthenware, and stoneware. Pottery is one of the oldest used ceramic applications.
- Earthenware is used widely for ceramic such as tableware and decorative objects. It is one of the oldest Abrasion Resistant Material used in pottery.
- Stoneware clay is non-porous, glaze material applied only for decoration. It is a sturdy, chip-resistant and durable material.
- Porcelain is a very hard, translucent white ceramic. It also known as fine china products.
- Bone china – which is easier to make and is stronger than porcelain. It is made by adding ash from cattle bones to clay, or fine silica sand.
What are advanced ceramic materials?
The
Advanced ceramics are not clay-based material; however, these are highly
advanced oxides or non-oxides or combinations materials used in various
industrial applications:
- Oxides: alumina (Al2O3) and Zirconia (ZrO2).
- Non-oxides: Boron carbide (B4C), Silicon carbide (SiC) and Molybdenum disilicide (MoSi2).
Applications of advanced ceramics:
Advanced
ceramic materials have been established in many areas of everyday use. These
have utilization from fridge magnets to an increasing range of industries.
Industries like including metals production and Abrasion Resistant Ceramic processing, aerospace, electronics,
personnel protection and automotive have advanced ceramics application.
