The invention discloses an integral sagger for sintering lithium manganese iron phosphate and a preparation method of the integral sagger. The preparation method comprises the following specific steps: S1, preparing a mixture; the mixture is formed by mixing calcium hexaluminate particles, silicon carbide particles, calcium hexaluminate fine powder, silicon oxynitride fine powder, silicon carbide fine powder and pure calcium aluminate cement fine powder; s2, sequentially adding potassium tripolyphosphate and a potassium fluozirconate solution into the mixture, and stirring to obtain a castable; s3, the castable is placed in a mold to be subjected to pouring vibration forming, curing and demolding, and a sagger green body is obtained; and S4, the sagger green body is subjected to heat treatment after being dried and cooled to the room temperature, and the integral sagger for lithium manganese iron phosphate sintering is obtained. The method is simple in process, and the prepared saggar is high in density, high in strength, high in erosion resistance and permeability resistance and high in thermal shock stability.
本发明公开了一种磷酸锰铁锂烧结用整体匣钵及其制备方法。制备方法具体步骤如下：S1.配制混合料；所述混合料由六铝酸钙颗粒、碳化硅颗粒、六铝酸钙细粉、氧氮化硅细粉、碳化硅细粉和纯铝酸钙水泥细粉混合而成；S2.向所述混合料中依次加入三聚磷酸钾和氟锆酸钾溶液搅拌得浇注料；S3.将浇注料置于模具中浇注振动成型，养护，脱模，得到匣钵生坯；S4.将所述匣钵生坯干燥后热处理，冷却至室温，即得磷酸锰铁锂烧结用整体匣钵。本发明的方法的工艺简单，所制备的匣钵致密度高、强度大，抗侵蚀和抗渗透性强，热震稳定性高。
