Method for preparing cordierite material by using ferrochrome waste residue and cordierite material thereof
The invention relates to the technical field of cordierite materials, in particular to a method for preparing a cordierite material from ferrochrome waste residues and the cordierite material prepared by the method. The method provided by the invention comprises the following steps: mechanically activating the ferrochrome waste residue to obtain activated ferrochrome waste residue, and the particle size D50 of the activated ferrochrome waste residue is not more than 1 mu m; and mixing the activated ferrochrome waste residues, aluminum oxide, AlF3 and V2O5, and carrying out ball milling, compression molding and sintering to obtain the cordierite material. According to the method provided by the invention, massive consumption of the ferrochrome waste residues is realized, the harm of the ferrochrome waste residues to the environment is relieved, and the waste of resources is reduced; meanwhile, a feasible new method is provided for reducing the production cost of the cordierite.
本发明涉及堇青石质材料技术领域，具体涉及一种利用铬铁废渣制备堇青石质材料的方法及其堇青石质材料。本发明提供的方法，包括如下步骤：对铬铁废渣进行机械活化，得到活化后的铬铁废渣，活化后的铬铁废渣的粒径D50不大于1μm；将活化后的铬铁废渣、氧化铝、AlF3和V2O5混合后球磨、压制成型、烧成，得到堇青石质材料。本发明提供的方法不仅实现了铬铁废渣的大量消耗，缓解了铬铁废渣对环境的危害，降低了资源的浪费；同时为降低堇青石的生产成本提供了一个切实可行的新方法。
