Zirconium carbide ceramic hollow microspheres and preparation method thereof
The invention relates to zirconium carbide ceramic hollow microspheres and a preparation method thereof. The method comprises the following steps: carrying out spray drying on a precursor solution containing polyzirconoxane, phenolic resin and a solvent to obtain precursor hollow microspheres; subjecting the hollow microspheres sequentially to binder removal carbonization and sintering to obtain the zirconium carbide ceramic hollow microspheres. According to the preparation method, the polyzirconoxane and the phenolic resin are used as raw materials, a spray drying method is adopted, high-pressure conditions are not involved, the process is simple, the problem that in the prior art, industrial large-scale production is not easy is solved, and the problem that existing ceramic hollow microspheres are low in temperature resistance is also solved.
本发明涉及一种碳化锆陶瓷空心微球及其制备方法。一种碳化锆陶瓷空心微球的制备方法，包括下列步骤：将含有聚锆氧烷、酚醛树脂和溶剂的前驱体溶液喷雾干燥，得到前驱体空心微球；将所述空心微球依次排胶碳化、烧结，得到碳化锆陶瓷空心微球。本发明以聚锆氧烷、酚醛树脂为原料，采用喷雾干燥法，不涉及高压条件，且工艺简单，既解决了现有技术不容易工业化大规模生产的问题，也解决了现有陶瓷空心微球耐温性低的问题。
