    2016-10-24 · We recently developed a novel technique of cold sintering process (CSP) to obtain dense ceramics at extraordinarily low temperatures. In this communication, we demonstrate the feasibility of applying CSP to zirconia-based ceramics. As exemplified by 3Y-TZP ceramics, a significantly enhanced densification evolution is observed.

  • Liquid Phase Sintering - an overview | ScienceDirect Topics

    Liquid phase sintering (LPS) is a key technique for fabricating traditional as well as modern ceramic materials and components. This article addresses the fundamentals of LPS with respect to its basic phenomena, densification, grain growth and microstructural evolution. The role of the liquid matrix on these phenomena is discussed.
