总结了闪烧研究中所涉及的实验内容(包括平台、制度和材料体系等)和烧结机理(包括焦耳热效应、快速升温致密化、接触点局部热效应和缺陷作用理论等),比较了闪烧和传统烧结制得材料的微观形貌和力学性能,展望了闪烧技术的发展趋势和方向。结果表明:闪烧技术可广泛应用于离子导体、绝缘体、半导体和类金属导电陶瓷等多种陶瓷材料的制备中,闪烧制备的陶瓷材料较传统烧结具有更精细的微观形貌和更优异的力学性能。
The experimental contents (including platform, system and material system) and sintering mechanism (including Joule heating effect, rapid temperature increase and densification, local thermal effect at contact point and the theory of defects) were summarized. The effects of flash and The microstructure and mechanical properties of the materials prepared by conventional sintering are discussed. The development trend and direction of the flash burning technology are also prospected. The results show that the flash-burning technology can be widely used in the preparation of a variety of ceramic materials, such as ion conductors, insulators, semiconductors and metal-like conductive ceramics. The flash fired ceramic materials have finer micromorphology and more excellent Mechanical properties.
