An Overview on Ceramics

 

The word ‘ceramic’ is originated from Greek word keromikos, which means ‘burnt stuff’. Ceramics are compounds of metallic and non-metallic elements.

Characteristics of Ceramics

– high temperature stability

– high hardness – brittleness

– high mechanical strength

– low elongation under application of stress

– low thermal and electrical conductivities

Types of Ceramics

Ceramics are classified in many ways. It is due to divergence in composition, properties and applications.

ceramic material

Based on their composition, ceramics can be divided into:

– Oxides

– Carbides

– Nitrides

– Sulfides

– Fluorides etc.

Based on their specific applications, ceramics are classified as:

– Glasses

– Clay products

– Refractories

– Abrasives

– Cements

– China Special Ceramic Parts for special applications

Based on their engineering applications, ceramics are classified into two groups as:

– Traditional ceramics – most made-up of clay, silica and feldspar

– Engineering ceramics – these consist of highly purified aluminium oxide (Al2O3 ), silicon carbide (SiC) and silicon nitiride (Si3N4 )

ceramic materials

The very specific feature of ceramics

– high temperature stability

– makes conventional fabrication routes unsuitable for ceramic processing

Inorganic glasses, though, make use of lower melting temperatures: Most other ceramic products are manufactured through powder processing.

Typical ceramic processing route

Powder synthesis – green component (casting, extrusion, compaction) – sintering / firing.
