The invention discloses an aluminum ash based porous ceramic material and a preparation method thereof. High-pressure dry forming and firing to obtain aluminum ash-based porous ceramic materials. The method is simple to operate, no water is involved in the preparation process, avoids the release of harmful gases from the reaction of aluminum ash with water, and all raw materials are solid waste, no additional commercial chemical reagents are added, and the cost is low, and the prepared porous ceramic material has a small bulk density and high strength. , Good solidification effect on heavy metals, no secondary pollution. |
