High vacuum furnace
Supervisor: Jan Hostaša
The application of vacuum during sintering helps to densify the material by the removal of air that otherwise would remained entrapped inside pores, and by the enhancement of diffusion. Vacuum sintering is also favorable for materials that react with air at elevated temperatures, or for the production of transparent ceramics, avoiding the contamination from the atmosphere.
At CNR ISTEC the vacuum furnace is used for the production of transparent ceramics.
High vacuum furnace LPA Cristal
- The furnace works under high vaccum (10-4 Pa) and clean atmosphere;
- the chamber and heating elements are completely made from tungsten and molybdenum, without graphite components;
- sintering temperature up to 1750 °C.
