摘要: Advanced sintering techniques for consolidation of Si3N4 powders in the presence an oxygen-rich liquid phase(s) require high temperatures and usually nitrogen pressures. A stability diagram is constructed as a function partial pressures (PN2) silicon (PSi). High PN2 (20 to 100 atm) increases phase by reducing PSi PSi0, respectively. The region sinterability outlined submicrometer containing 7 wt% BeSiN2 SiO2 densification aids.
