Special sagger for sintering sodium battery positive electrode material and preparation method of special sagger
The invention discloses a special sagger for sintering a sodium battery positive electrode material and a preparation method of the special sagger. The preparation method comprises the following steps: S1, mixing premixed granules and premixed fine powder according to a certain mass ratio to obtain a mixture, adding a certain amount of potassium fluozirconate solution into the mixture, and stirring to obtain a castable; s2, the castable is subjected to pouring vibration molding, curing and demolding, and a sagger green body is obtained; and S3, drying the sagger green body for a period of time, and performing high-temperature heat treatment for a period of time to obtain the special sagger for sintering the sodium battery positive electrode material, wherein the premixed particle material comprises calcium hexaluminate particles and fused zirconia corundum particles; the premixed fine powder comprises calcium hexaluminate fine powder, calcium dialuminate fine powder, dodecacalcium heptaaluminate fine powder, calcium acetate fine powder and rare earth composite yttrium zirconium ceramic powder. The process is simple, and the prepared sagger is high in density, high in strength, high in permeability resistance, good in erosion resistance and high in thermal shock stability.
本发明公开了一种钠电正极材料烧结专用匣钵及其制备方法。制备方法包括如下步骤：S1、将一定质量比的预混颗粒料和预混细粉料进行混合得到混合料，向所述混合料中加入一定量的氟锆酸钾溶液搅拌后得浇注料；S2、将浇注料浇注振动成型，养护，脱模，得到匣钵生坯；S3、将所述匣钵生坯干燥一段时间后，高温热处理一段时间，得钠电正极材料烧结专用匣钵；其中，所述预混颗粒料包括六铝酸钙颗粒和电熔锆刚玉颗粒；所述预混细粉料包括六铝酸钙细粉、二铝酸钙细粉、七铝酸十二钙细粉、乙酸钙细粉和稀土复合钇锆陶瓷粉。本发明工艺简单，所制备的匣钵致密度高、强度大，抗渗透性强，抗侵蚀性好，热震稳定性高。
