一种单相MgSiN2粉体的制备方法
本发明公开一种单相MgSiN2粉体的制备方法，包括如下步骤：将镁粉、氮化硅粉和氮化硅镁粉按一定比例混合均匀得到混合粉体，在氮气‑氩气混合气氛下诱发混合粉体发生自蔓延燃烧反应，得到单相MgSiN2陶瓷粉体。本发明通过采用氮化硅镁粉和氮气‑氩气混合气体，降低燃烧反应温度、抑制反应过程中镁的蒸发损失，得到单相MgSiN2粉体。本发明制备的MgSiN2粉体纯度高，制备方法具有能耗低、周期短和成本低等技术优势。
The invention discloses a preparation method of single-phase MgSiN2 powder, which comprises the following steps: uniformly mixing magnesium powder, silicon nitride powder and silicon magnesium nitride powder according to a certain proportion to obtain mixed powder, and inducing the mixed powder to generate self-propagating combustion reaction in a nitrogen-argon mixed atmosphere to obtain the single-phase MgSiN2 ceramic powder. By adopting the silicon magnesium nitride powder and the nitrogen-argon mixed gas, the combustion reaction temperature is reduced, the evaporation loss of magnesium in the reaction process is inhibited, and the single-phase MgSiN2 powder is obtained. The prepared MgSiN2 powder is high in purity, and the preparation method has the technical advantages of being low in energy consumption, short in period, low in cost and the like.
