Die Pressing(also called dry press in china)

This is by far the most widely used shaping technique for advanced ceramics
Ceramic powder is contained within a hopper and fill the die cavity.The top punch of the die will come down and compress the Granular powder  within the cavity to form the green body.Adjust mold and press machine is important.

Isostatic Pressing

Granular powder or die pressed compacts are loaded into a flexible air-tight container, placed in a closed pressure vessel filled with liquid and compacted by increasing the pressure.The pressure change takes place throughout the liquid, thus exerting a uniform applied pressure over the entire surface area of the air-tight container. In this way, the material is uniformly compacted

Extrusion

Ceramic powders and organics are added to a special mixing device and intimately mixed together
The resultant mix is removed from the mixer and added to the extrusion chamber.Then proceeds to extrude ceramic through shaped tooling under high pressure

Tape Casting

This process involves the casting of a slurry onto a flat moving carrier surface. The slurry usually consists of a ceramic powder with the appropriate additions of solvents plasticisers and binders.The slurry passes beneath the knife edge as the carrier surface advances along a supporting table.

Injection Moulding

Low pressure injection moulding needs much lower cost tools.By this technology,complex shapes can be made.

Using special mixing device, Ceramic powders and organics are mixed together
The resultant mix is granulated and fed into an injection moulding machine
The ceramic flow under pressure into a mould
The mould and the formed ceramic component is cooled quickly to form a solid
Split The mould and the solid ceramic component is ejected

Reaction bonded Silicon carbide

Reaction bonded Silicon carbide is made by infiltrating compacts made of mixtures of SiC and Carbon with liquid Silicon. The Silicon reacts with the Carbon forming more SiC which bonds the initial SiC particles.

Sintered Silicon carbide

Sintered Silicon carbide is produced from pure SiC powder with non-oxide sintering aids. Conventional ceramic forming processes are used and the material is sintered in an inert atmosphere at temperatures up to 2000 degree or higher.
