Formula and process for preparing foamed ceramic from aluminum ash and ceramic polishing slag
The invention relates to the field of composite material production, in particular to a formula and a process for preparing foamed ceramic by using aluminum ash and ceramic polishing slag, the foamed ceramic uses original high-content silicon carbide and aluminum oxide components in the ceramic polishing slag as main raw materials, and uses more metal oxidation elements in secondary aluminum ash as auxiliary materials; the foaming rate in the foaming process is reduced, the compactness of the prepared foamed ceramic and the consistency of foam holes are improved, the compressive hardness and breaking strength of the prepared foamed ceramic can be improved, addition of additional foaming agents is reduced, energy consumption and pollution can be remarkably reduced through the dry-method powder preparation technology, the ceramic polishing residues and the aluminum ash are prepared into the foamed ceramic, and the resource utilization rate can be increased; the production cost is reduced.
本发明涉及复合材料生产领域，尤其涉及一种利用铝灰及陶瓷抛光渣制备发泡陶瓷的配方及工艺，本发明发泡陶瓷利用陶瓷抛光渣中原有较高含量的碳化硅、氧化铝成分作为主原料，辅以二次铝灰中较多的金属氧化元素，降低发泡过程中发泡率，提高制得发泡陶瓷的致密性和泡孔的一致性，能提高制得发泡陶瓷的抗压硬度和抗折强度，减少额外发泡剂的添加，利用干法制粉工艺能显著降低能耗和污染，将陶瓷抛光渣和铝灰制成发泡陶瓷能提高资源利用率，降低生产成本。
