摘要

采用自推进高温合成（SHS）技术制备了基于 Si3N4-Yb2O3 体系的 SHS 成分。合成在 4 兆帕的氮气环境下，在一个 30 升的反应器中进行。装料重量为 3 千克。结果表明，装料中的氧化镱量会影响燃烧温度和合成产物的相组成。随着装料中氧化镱比例的增加，α-Si3N4 的含量减少，次生相为四硅氧氮化镱和二硅酸镱。

Ytterbium Oxide Influence on the SHS Parameters and Phase Make-Up of Silicon Nitride Based Compositions

Self-propagating high-temperature synthesis (SHS) was used to prepare SHS compositions based on the system Si₃N₄–Yb₂O₃ system. Synthesis was conducted in a nitrogen atmosphere at 4 MPa in a 30 L reactor. The weight of the loaded charge was 3 kg. It was ascertained that the amount of ytterbium oxide in the charge affects the combustion temperature and the phase composition of the synthesis products. As the proportion of ytterbium oxide in the charge increases, the α-Si₃N₄ content decreases, and the secondary phases are represented by quaternary silicon ytterbium oxynitride and ytterbium disilicate.
