多孔陶瓷制备技术的进展

Preparation and development of porous ceramics

多孔陶瓷是一种含有较多孔隙的无机功能材料,在化工、冶金、运输等领域有着广泛的应用前景。对多孔陶瓷的制备技术及最新研究进展进行了详细的综述,报道了一种在自蔓延高温合成法和发泡法基础上创新的制备方法——自蔓延高温合成喷射法,并对未来研究方向进行了展望,认为今后对多孔陶瓷制备技术的研究将沿着对现有技术进行改进及结合其他种类材料的制备技术进行创新等两个方向开展。

As a group of inorganic functional materials, porous ceramics are extensively applied in chemical industry, metallurgy, transport, etc. The author summarized the technology for preparation of porous ceramics and reported a new technology the self-propagating high-temperature synthesis （SHS） jetting, an in-novated procedure based upon the SHS process and foaming process. The author also forecasted that further research of porous ceramics would develop along tWO directions ： improvement on existing processing methods and innovation integrated with the technologies for preparation of other materials.
