Dépôt d'une matrice contenant une poudre céramique dans un four en vue d'une opération de frittage

Placing a die containing a non-oxide ceramic powder into a furnace at 1700°C for sintering. This heat will bind the grains of this refractory material. To consolidate a material, it is necessary to reach around 70% of its melting temperature. After that, these materials must be characterised by performing high-temperature tests (at 2000°C) and exposing them to oxidising atmospheres. These ceramic materials, which are resistant to high temperatures and oxidising atmospheres, are used in the aerospace and nuclear (fuel pellet protective cladding) sectors, and even on the catalytic converters in our cars.
