Method for preparing functional ceramic engineering material combustion-supporting catalyst from coal solid waste or bauxite solid waste
The invention relates to the technical field of engineering materials, in particular to a method for preparing a functional ceramic engineering material combustion-supporting catalyst from coal solidwaste or bauxite solid waste. The method comprises the following steps: 1, selecting raw materials; 2, stacking the sample space, feeding into a flat furnace, and heating to 850 DEG C for 2 hours; 3,heating from 850 DEG C to 950 DEG C at a speed of 300 DEG C/h, roasting for 4-5 hours, and naturally cooling; 4, crushing the sample; 5, crushing the crushed sample to 100 meshes; 6, measuring the lithium content; 7, directly and finely grinding the batch of raw materials of which the lithium content is greater than 0.1% in the sample to 325-1000 meshes; 8, adding TiO2 powder, and carrying out ball milling to obtain powder with the particle size of 10-100 nanometers; and 9, calcining the prepared powder at 1100 DEG C for 4 hours to prepare the required combustion-supporting catalyst. When thecombustion-supporting catalyst rich in lithium, gallium, vanadium and titanium rare elements prepared by the method is used for preparing a functional ceramic engineering material, the sintering temperature is remarkably reduced, the strength of the ceramic engineering material is improved, and the density of the engineering material is reduced.
本发明涉及工程材料技术领域，具体涉及一种利用煤炭固废或铝矾土固废制备功能陶瓷工程材料助燃催化剂的方法；包括以下步骤：1，选取原料；2，样品空间堆积，并送入平炉2h升温至850℃；3，将温度由850℃以300℃/h升温至950℃，焙烧4～5h，自然降温；4，破碎样品；5，将破碎后的样品粉碎至100目；6，测定锂含量；7，将样品中锂含量>0.1%批次的原料直接细磨至325～1000目；8，加入TiO粉末进球磨制成粒径10～100纳米级粉料；9，将配好的粉料1100℃煅烧4h，制成所需的助燃催化剂；利用本发明方法制备出的富含锂鎵钒钛稀有元素的助燃催化剂制备功能陶瓷工程材料时，显著降低了烧结温度并提高了陶瓷工程材料的强度，降低了工程材料的密度。
