摘　　要：综述了ZrW2O8在金属基、氧化物陶瓷基、水泥基和聚合物基复合材料中的应用情况。重点介绍了Cu-ZrW2O8、Al-ZrW2O8、ZrO2-ZrW2O8、Cement-ZrW2O8、Polyimide-ZrW2O8等复合材料的研究成果和存在的问题;提出了ZrW2O8可控热膨胀系数的复合材料未来研究方向。In this paper, the applications of ZrW2O8 in the metal-based, oxide ceramic-based, cement-based and polymer-based composites are reviewed. In order to develop low thermal expansion or nearly zero thermal expansion composites, Cu-ZrW2P8, Al-ZrW2O8, ZrO2-ZrW2O8, Cement-ZrW2O8 and Polyimide-ZrW2O8 composites are prepared by different methods. The recent research achievements and existing problems on such composites are summarized in particular. The future studies of ZrW2O8 composites with controllable coefficient of thermal expansion are also pointed out in this paper.
