Preparation method of nitride whisker in-situ reinforced cordierite heat storage ceramic
The invention discloses a preparation method of nitride whisker in-situ reinforced cordierite heat storage ceramic, which comprises the following steps: by taking a natural aluminosilicate mineral-magnesian mineral-metal silicon powder-siliceous raw material as a raw material system, introducing nitride whiskers and a cordierite matrix in an in-situ synthesis manner; and the combination of the seed crystal and the catalyst is combined, so that the in-situ synthesis temperature of the nitride crystal whiskers is reduced, and the yield of the crystal whiskers is increased, thereby obtaining the nitride crystal whisker in-situ reinforced cordierite heat storage ceramic with high performance and low cost. The problem that industrial powder and aggregate are not easy to mix uniformly in the prior art is effectively solved, the performance of the cordierite heat storage ceramic is improved, the raw materials are easy to obtain, the process is simple, the firing temperature is low, the yield is high, and the cordierite heat storage ceramic has important significance in improving the quality of the cordierite heat storage ceramic and saving the product cost and has wide application prospects. And popularization and application as well as progress and development of the industry technology are facilitated.
本发明公开了一种氮化物晶须原位增强堇青石质蓄热陶瓷的制备方法，采用天然铝硅酸盐矿物‑镁质矿物‑金属硅粉‑硅质原料为原料体系，通过原位合成方式引入氮化物晶须和堇青石基体，并结合晶种+催化剂的组合降低了氮化物晶须的原位合成温度、提高了晶须的产量，从而获得了高性能、低成本的氮化物晶须原位增强堇青石质蓄热陶瓷。本发明不仅有效解决了现有技术工业粉料和骨料不易混匀的问题，提高了堇青石质蓄热陶瓷的性能，而且原料易得、工艺简单、烧成温度低、成品率高，对于提高堇青石质蓄热陶瓷的品质、以及节约产品成本具有重要意义，有利于推广应用和行业技术的进步与发展。
