2010-1-21 · sintered boron carbide because of the proprietary nature of this material. One method of making the dense polycrystalline boron carbide is by hot pressing (including hot isostatic pressing)1. In some cases densification is conducted by hot pressing (1900-2200°C at 0.02-0.04 GPa for 15-45 min) in graphite dies under vacuum or argon atmosphere.

Hot pressing - Wikipedia

2020-1-11 · Hot pressing is a high-pressure, low-strain-rate powder metallurgy process for forming of a powder or powder compact at a temperature high enough to induce sintering and creep processes. This is achieved by the simultaneous application of heat and pressure. Hot pressing is mainly used to fabricate hard and brittle materials.

Vacuum Sintering Furnaces High-Temp Sintering …

Sintering starts with debinding. The debinding process removes binder materials that can contaminate the furnace and the final product. Binding materials are originally necessary for each separate part compaction, but become unnecessary and undesirable during the sintering process. Vacuum sintering requires a high vacuum for clean, quality parts.

8.1. Introduction. Vacuum sintering became a relevant technology when first used for the sintering of the Group VA elements – V, W, Ta, Mo, Nb, etc. 1 The method was actually a reactive sintering approach where carbon was added to reduce the oxygen from the metal via carbon monoxide evolution under vacuum. This method produced a ductile metal and a modern sintering technology was born.
