High-alumina fly ash foamed ceramic material as well as preparation method and application thereof

The invention relates to the technical field of foamed ceramics, in particular to a high-alumina fly ash foamed ceramic material as well as a preparation method and application thereof, and the ceramic material is prepared from the following raw materials in percentage by weight: 50-60% of high-alumina fly ash, 5-10% of a stabilizer, 0.1-0.3% of a foaming agent, 5-10% of a sintering aid and the balance of solvent substances. The special high-alumina fly ash in the Inner Mongolia region is added as a main raw material, so that the compressive strength and the firing temperature of the foamed ceramic are remarkably improved, and the foamed ceramic has the unique advantages of wide raw material source, low price and good thermal stability; the prepared foamed ceramic material is especially suitable for building materials with high fireproof and sound insulation requirements, such as non-bearing walls such as hotel walls and KTV compartment walls, and has good fireproof and sound insulation effects. 本发明涉及发泡陶瓷技术领域
