What are Sintered Ceramics?
Sintered ceramics are advanced ceramic materials formed by compacting fine powders and densifying them at high temperatures below their melting point. As the particles are heated, atomic diffusion fuses the particles, eliminating porosity and producing a strong stable micro-structure with good hardness, heat resistance, and chemical resistance.
In traditional and high-performance applications, they have served leady ther with the capacity to control density, grain size and functional properties via powder composition and sintering conditions. Hence, sintered ceramics are suitable for harsh environment that metals or polymers could not fit.
How are Sintered Ceramics Made?
Sintered ceramics are made by shaping fine ceramic powders into a compact form and then heating them to a high temperature that is below their melting point. The powders are first prepared with controlled particle size and selected additives, and then pressed into a green body that has the intended shape but low strength.
During the sintering stage, the green compact is heated in a controlled environment. The particles begin to bond through atomic diffusion and the internal pores gradually shrink. This produces a strong and dense ceramic structure with stable mechanical and thermal properties.
After sintering the ceramic part is cooled and can be finished through machining, grinding, or polishing to achieve the required dimensions and surface quality.

FAQ's
Here are some of the questions we get asked often. If yours isn’t answered, don’t hesitate to contact us, we’re happy to help!
There are two main reasons why white alumina changes to pale yellow.
- The internal chemical composition of alumina changes due to sunlight exposure.
- The alumina may have deliquesced, producing hydrated alumina.
Dry Pressing
Dry pressing involves using a powder press to compact ceramic powder into shape, allowing for the manufacture of parts with heights ranging from 0.3 to 60 mm and diameters from 5 to 500 mm.
Powder Injection Molding
Ceramic powder injection molding is similar to metal injection molding, where ceramic powder is shaped using an injection machine.
The advantage of this method is its ability to create small, complex shapes, but it is not suitable for producing large-sized components.
Isostatic Pressing
Isostatic pressing is ideal for creating complex shapes or large, elongated products. This method can produce high-density and uniform parts.
