Cordierite honeycomb ceramic as well as preparation method and application thereof
The invention provides cordierite honeycomb ceramic and a preparation method and application thereof, preparation raw materials of the cordierite honeycomb ceramic comprise a main material and a mineralizer, and the main material comprises kaolin, talc and an aluminum source; the addition amount of the mineralizing agent is less than 1.5 wt% of the addition amount of the main material. According to the cordierite honeycomb ceramic disclosed by the invention, the growth of cordierite crystals in the A-axis direction is promoted by adding a specific content of mineralizer into the preparation raw materials, so that a cordierite honeycomb ceramic carrier with the expansion coefficient of less than or equal to 0.3 * 10 <-6 >/DEG C can be obtained.
本发明提供了一种堇青石蜂窝陶瓷及其制备方法与应用，所述堇青石蜂窝陶瓷的制备原料包括主料和矿化剂，所述主料包括高岭土、滑石和铝源；所述矿化剂的添加量在所述主料添加量的1.5wt％以下。本发明所述堇青石蜂窝陶瓷通过在制备原料中添加特定含量的矿化剂，促进堇青石晶体在A轴方向上生长，从而能够得到膨胀系数≤0.3×10‑6/℃的堇青石蜂窝陶瓷载体。
