Graphite for Sintering

Mersen graphite is very widely used in pressure sintering processes.

It enables the fabrication of sintering moulds which in turn are used to produce diamond or ceramic cutting tools, and ceramic armour elements for military applications. 

Our customers particularly appreciate the excellent performance characteristics of Mersen iso-moulded graphite in these high-temperature processes. 

The combination of exceptional thermal conductivity and a low coefficient of thermal expansion is an essential element to ensure the dimensional stability of sintering moulds.

A well-controlled coefficient of thermal expansion

Understanding changes in the coefficient of thermal expansion is very important when designing a sintering mould. Our grades have been studied over a wide range of temperatures and offer remarkable stability.

A selection of grades according to applications

The material used to manufacture a sintering mould is selected based on the process temperature and pressure requirements. Some of our grades are selected when the material's electrical and thermal conductivity are the prioritised parameters in order to reduce cycle time. When the process pressure is too high, the mechanical strength of the mould is prioritised. Our experts are at your disposal to discuss the best grades adapted to your specific needs.
