有机元素聚合物的热解为制备高纯度、高性能陶瓷提供了一条强有力的途径。研究了影响聚合物硅氮烷生产低氧含量陶瓷纤维的各种因素，并描述了通过改变热解气氛来控制纤维组成的可能性，从而产生稳定的非晶相。该纤维在增强金属基和陶瓷基复合材料方面具有很大的潜力。
The pyrolysis of organoelemental polymerssprovides a powerful route to high‐ppurity, high‐performance ceramics. The various factors influencing the production of low‐oxygen‐content ceramic fibers from polymeric silazanes are examined and the possibility of controlling the composition of the fibers by varying the pyrolysis atmosphere resulting in stable, amorphous phases is described. The fibers have great potential in the reinforcement of metal and ceramic matrix composites.
