Cordierite honeycomb ceramic carrier with low thermal expansion coefficient as well as preparation method and application of cordierite honeycomb ceramic carrier
The invention relates to the technical field of honeycomb ceramic materials, in particular to a cordierite honeycomb ceramic carrier with a low thermal expansion coefficient, a preparation method and application. The cordierite honeycomb ceramic carrier is prepared from raw materials containing fibrous brucite, calcined kaolin and crystalline quartz. The fibrous brucite, the calcined kaolin and the crystal quartz adopted by the invention all have the advantages of low price and wide source, and on the basis of not using aluminum oxide, not only is the preparation cost effectively reduced, but also the prepared cordierite honeycomb ceramic carrier has the advantages of high firing qualification rate and ultralow expansion coefficient. The thermal expansion coefficient of the cordierite honeycomb ceramic carrier can be less than or equal to 0.3 * 10 <-6 >/DEG C.
本发明涉及蜂窝陶瓷材料技术领域，具体而言，涉及低热膨胀系数堇青石质蜂窝陶瓷载体、制备方法及应用。所述堇青石质蜂窝陶瓷载体由含有纤维状水镁石、煅烧高岭土以及结晶石英的原料制得。本发明采用的纤维状水镁石、煅烧高岭土以及结晶石英均具有价格低廉、来源广的优点，在不使用氧化铝的基础上，不仅有效降低了制备成本，而且制备得到的堇青石质蜂窝陶瓷载体具有烧成合格率高、膨胀系数超低的优点。该堇青石质蜂窝陶瓷载体的热膨胀系数可小于或等于0.3×10‑6/℃。
