Aluminum titanate-mullite composite ceramic and preparation method thereof, porous medium combustor and ceramic filter
The invention discloses an aluminum titanate-mullite composite ceramic and a preparation method thereof, a porous medium combustor and a ceramic filter, and belongs to the technical field of ceramics. The aluminum titanate-mullite composite ceramic comprises an aluminum titanate crystal phase and a mullite crystal phase in a mass ratio of (6-7):(3-4); and the stable component of the aluminum titanate-mullite composite ceramic is selected from at least one of magnesium oxide, strontium oxide, silicon dioxide, ferric oxide, cerium oxide, lanthanum trioxide and yttrium oxide. The aluminum titanate-mullite composite ceramic disclosed by the embodiment of the invention has good sintering strength and thermal shock resistance at the same time, and the defects that the existing aluminum titanate ceramic is easy to break and low in sintering strength are improved.
一种钛酸铝‑莫来石复合陶瓷及其制备方法、多孔介质燃烧器及陶瓷过滤器，属于陶瓷技术领域。钛酸铝‑莫来石复合陶瓷包括质量比为6～7:3～4的钛酸铝晶相和莫来石晶相；钛酸铝‑莫来石复合陶瓷的稳定成分选自氧化镁、氧化锶、二氧化硅、三氧化二铁、氧化铈、三氧化二镧和氧化钇中的至少一种。本申请实施例的钛酸铝‑莫来石复合陶瓷同时具有良好的烧结强度和抗热震性能，改善了现有钛酸铝陶瓷的容易断裂和烧结强度低的缺点。
