In recent years, novel rapid sintering techniques, i.e., induction sintering, microwave sintering, spark plasma sintering, hot pressing, and hot isostatic pressing, could achieve densification of powders in several minutes, which is beneficial to the control of oxygen content increase and grain growth.
