摘要

本文报道了Si3N4-Yb2O3体系中自传播高温合成组分的系统研究。在我们的制备中，起始混合物的氧化镱含量从4%到20%不等。氧化镱影响了合成产物的燃烧温度、颗粒形态和相组成。增加氧化镱在起始混合气中的比例可以提高燃烧温度。优化了氮化硅α相含量高的合成条件。

Self-Propagating High-Temperature Synthesis of Compositions in the Si3N4–Yb2O3 System

We report a systematic study of the self-propagating high-temperature synthesis of compositions in the Si₃N₄–Yb₂O₃ system. In our preparations, the ytterbium oxide content of the starting mixture was varied from 4 to 20 wt %. Ytterbium oxide has been shown to influence the combustion temperature, particle morphology, and the phase composition of synthesis products. Increasing the percentage of ytterbium oxide in the starting mixture has been found to increase the combustion temperature. We have optimized conditions for the synthesis of compositions with a high content of the alpha-phase of silicon nitride.
