Silicon Nitride

Sintered Ceramics: Silicon Nitride

Final Advanced Materials manufactures ceramic parts with precision. From the blanks obtained by moulding or extrusion, we get these shaped parts by diamond machining for dense ceramics.

We provide the definition and machining of prototypes, as well as the individual production in small and large series. We design and machine the ceramic components adapted to specific customer applications.

We only work with calibrated and qualified ceramics of high purity. The ceramic parts that we transform, reproduce without modification, the physical characteristics of the blanks before machining, without any variation or mechanical depreciation. 

The intrinsic properties to ceramics, i.e. hardness, abrasion resistance, compressive strength, resistance to high temperatures, to thermal shocks, high dielectric strength, all these qualities are preserved and reproduced on the finished parts.

Silicon nitride is a particularly important ceramic of its type, as it features a unique combination of properties. It is extremely hard, highly resistant to thermal impacts, chemical products and wear, even at high temperatures, and features a low coefficient of thermal expansion, in combination with average thermal conductivity.
