Foamed ceramic prepared from fly ash and metallurgical waste residues and preparation method of foamed ceramic
The invention belongs to the field of ceramic materials, and relates to foamed ceramic prepared from fly ash and metallurgical waste residues and a preparation method of the foamed ceramic. The preparation method comprises the following steps: by taking fly ash, silicomanganese slag and vanadium slag as main raw materials, borax as a melting aid, caustic calcined magnesia powder as a foam stabilizer, bentonite as a binder and silicon carbide as a foaming agent, conducting mixing according to a certain ratio, conducting crushing, carrying out ball milling, adding a certain mass of water, conducting aging, putting the system into a tablet press, carrying out compression molding, and conducting sintering to prepare the foamed ceramic. According to the invention, the doping ratio of the solid waste can reach up to 80%, and the utilization efficiency of the solid waste is greatly improved. The prepared foamed ceramic can be used in thermal insulation and decoration materials, realizes the purpose of turning waste into wealth, is a breakthrough in comprehensive utilization of solid wastes, and expands the field of large-dosage utilization of industrial solid wastes.
本发明属于陶瓷材料领域，涉及一种利用粉煤灰和冶金废渣制备的发泡陶瓷及其制备方法。本发明是利用粉煤灰、硅锰渣和钒渣为主要原料，硼砂为助融剂，轻烧镁粉为稳泡剂，膨润土为粘结剂，碳化硅为发泡剂，按照一定的比例混合、粉碎、球磨，加入一定质量水陈化后，放入压片机中压制成型，进行烧结制备发泡陶瓷。本项目中固废的掺杂比例可以高达80%，大大提高了固废的利用效率。所制得发泡陶瓷可用于保温隔热、装饰装修材料中，实现了“变废为宝”，是固废综合利用的一项突破，为工业固废的大掺量利用拓展了领域。
