Cordierite honeycomb ceramic with crystal directional arrangement structure and preparation method of cordierite honeycomb ceramic
The invention relates to a cordierite honeycomb ceramic with a crystal directional arrangement structure and a preparation method thereof. A cordierite honeycomb ceramic with a crystal orientation arrangement structure is mainly prepared from fly ash, inorganic ligand powder is added based on a theoretical ratio, and a grain orientation agent, a binder, a plasticizer, a dispersant and water are added. The cordierite honeycomb ceramic material with the crystal oriented arrangement structure is prepared through pretreatment, high-energy ball milling, uniform mixing, extrusion and high-temperature solid-phase sintering, the method is simple, the purity of cordierite in the obtained product is high, the grain orientation degree is high, and the cordierite honeycomb ceramic material can be applied to the fields of catalyst carriers, heat accumulators and the like. According to the invention, the product performance can be improved while the product cost is reduced, and a large amount of solid waste fly ash is consumed so as to reduce the adverse effect on the environment.
本发明涉及一种具有晶体定向排列结构的堇青石蜂窝陶瓷及其制备方法。一种具有晶体定向排列结构的堇青石蜂窝陶瓷，主要原料为粉煤灰，基于理论配比外加无机配体粉料，并添加晶粒定向剂、粘结剂、塑性剂、分散剂和水。其中所述具有晶体定向排列结构的堇青石蜂窝陶瓷材料通过预处理‑高能球磨‑均匀混料‑挤出‑高温固相烧结制备得到，方法简单，所得产品中堇青石纯度高且晶粒定向度高，可应用于催化剂载体、蓄热体等领域。本发明可在降低产品成本的同时，提高产品性能，并消纳大量固体废弃物粉煤灰以减轻其对环境的不利影响。
