Honeycomb ceramic heat accumulator and preparation method thereof
The invention relates to a honeycomb ceramic heat accumulator and a preparation method thereof. The honeycomb ceramic heat accumulator comprises basic powder and a rare earth additive, wherein the adding amount of the rare earth additive accounts for 1-17 wt% of the basic powder, and the rare earth additive comprises at least one of cerium oxide, lanthanum oxide, yttrium oxide and niobium oxide. The acid and alkali corrosion resistance, density and compressive strength of the honeycomb ceramic heat accumulator can be effectively improved, so that the honeycomb ceramic heat accumulator has longer service life in an environment containing corrosive gas.
本发明涉及一种蜂窝陶瓷蓄热体及其制备方法，该蜂窝陶瓷蓄热体包括基础粉末、稀土添加剂；其中，所述稀土添加剂的添加量为基础粉末的1‑17wt％，所述稀土添加剂包括氧化铈、氧化镧、氧化钇、氧化铌中的至少1种。本发明可以有效提高蜂窝陶瓷蓄热体耐酸碱腐蚀性能、致密度和抗压强度，从而使其在含有腐蚀性气体环境下具有更长的使用寿命。
