Sintered Ceramics: Boron Nitride

Boron nitride BN, machinable ceramic

Sintered Boron 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.

Boron nitride can be easily machined to virtually any shape. In inert and reducing atmospheres, boron nitride is resistant to temperatures in excess of 2,000 °C. It shows low thermal expansion, although its dielectric strength is high. Moreover, it is not wetted by the majority of molten metals and slags, and can therefore be used as a receptacle for the majority of molten metals.
