Metallurgy School, UST Beijing, Beijing 100083, China）ABSTRACT The negative thermal expansion in some complex oxides has beenattributed to transverse thermal motion of A-O-M linkage composed of two-coordinate oxygenbridge bond, and the librationsand tilts of essentially rigid polyhedral blocks in openframework structure. The isotopic NTE materials have been finding moresubstantialapplications in composites and other relative technique fields.

氧化物材料负热膨胀机理邢献然摘要氧化物的负热膨胀性是由于在其开放式的骨架结构中，有二配位的桥氧键产生横向热运动，以及引起的多面体热摆动和耦合作用使非键合M-M1键距变短，导致单胞体积缩小；各向同性NTE氧化物在复合材料及其相关技术领域具有更广泛的应用价值。
