水热-热静压工艺制备陶瓷材料的研究进展

Research Progress on the Preparation of Ceramic Materials byHydrothermal Hot-pressing

陶瓷材料由于具有耐高温、高硬度、耐腐蚀等优点,已经广泛应用于通讯、电子、航空航天等高技术领域。但传统陶瓷烧结工艺所需温度高,对能源消耗大,直接导致材料成本高,极大限制了陶瓷材料的发展。水热-热静压工艺的发明大幅降低了陶瓷材料的制备温度,成为目前陶瓷材料领域极具前景的制备方法之一。本文结合国内外水热-热静压工艺制备陶瓷材料的研究进展,对水热-热静压工艺制备功能陶瓷、多孔陶瓷及其复合材料进行综述,并对其未来发展进行了展望。

Due to the advantages of high temperature resistance,high hardness and corrosion resistance,ceramic materials have been widely used in high-tech fields such as aerospace,military and medical.However,the high temperature required by the traditional ceramic sintering process and high energy consumption directly lead to high material costs,which greatly limits the development of ceramic materials.The invention of hydrothermal hot-pressing has greatly reduced the preparation temperature of ceramic materials,and has become one of the most promising preparation methods in the field of ceramic materials.In this paper,based on the research progress of ceramic materials prepared by hydrothermal hot-pressing,functional ceramics,porous ceramics and their composites prepared by hydrothermal hot-pressing are reviewed,and their future development is prospected.
