20191115In the study, 55 g of tungsten powder was axially pressed at a pressure of 500 MPa to obtain cylindrical tungsten compacts (diameter = 20 mm; thickness = 15 mm). These green compacts were subsequently sintered in a tube furnace at 1350 °C for 1.5 h in a high-purity hydrogen atmosphere. Download : Download high-res image (479KB)
A modern trend in vacuum furnace processing is a furnace that can be utilized for many different conditions. The furnace could have both a debinding and a vacuum sintering capability, a debinding and partial pressure sintering capability, or a combination of both debinding, high vacuum, and partial pressure.
