The invention discloses a lightweight high-purity alumina foam ceramic refractory brick and a preparation method thereof, and relates to the technical field of refractory bricks, and the technical scheme is as follows: high-purity alumina long fibers and alumina powder are used as ceramic aggregates, water is used as a solvent, an aluminum dihydrogen phosphate solution is used as a binder, and starch is used as a filler; sodium alpha-olefin sulfonate (AOS) and lauryl sodium sulfate (K12) are used as foaming agents, silicon resin polyether (MPS) is used as a foam stabilizer, and an ammonium salt solution is used as a ceramic dispersing agent. The aluminum oxide content of the product is larger than or equal to 99.0%, and the product can be used in a reducing atmosphere, has good resistance to alkaline steam such as Na2O and K2O, and is high in strength, low in density and better in heat insulation effect.
本发明公开了一种轻质高纯氧化铝泡沫陶瓷耐火砖及其制备方法，涉及耐火砖技术领域，其技术方案是：以高纯氧化铝长纤维、氧化铝粉为陶瓷骨料，以水为溶剂，以磷酸二氢铝溶液为粘结剂，淀粉为填充剂，以α‑烯基磺酸钠（AOS）和十二烷基硫酸钠（K12）为发泡剂，以硅树脂聚醚（MPS）为稳泡剂，以铵盐溶液为陶瓷分散剂。本产品氧化铝含量≥99.0%，可在还原气氛下使用，对Na2O、K2O等碱性蒸汽具有良好抗性，且强度高，密度低，隔热效果更佳。
