Method for preparing mullite composite ceramic by low-temperature sintering of bauxite tailings and potassium feldspar
The invention discloses a method for preparing mullite composite ceramic by low-temperature sintering of bauxite tailings and potassium feldspar, belonging to the technical fields of high-value utilization of tailings and ceramic preparation. According to the invention, bauxite tailings, potassium feldspar, bauxite clinker and lithium chinastone are adopted as main raw materials and are subjected to batching, ball milling, drying, forming and treatment via a low-temperature sintering process so as to obtain a mullite composite ceramic material. When the mullite composite ceramic is prepared by sintering the bauxite tailings and the potassium feldspar at low temperature, the additive amount of the bauxite tailings is high, a preparation process is simple, and cost is relatively low; and potassium feldspar and lithium chinastone are added, so a sintering temperature can be reduced, energy consumption is reduced, and the compressive strength and density of the product can be improved. A new thought is provided for comprehensive application of the bauxite tailings, and the method has profound economic value and environmental protection significance.
本发明公开了一种利用铝矾土尾矿和钾长石低温烧结制备莫来石质复相陶瓷的方法，属于尾矿高值利用和陶瓷制备技术领域。本发明采用铝土矿尾矿、钾长石、铝钒土熟料及锂瓷石为主要原料，经过配料、球磨、干燥、成型、低温烧结工艺进行处理得到的莫来石质复相陶瓷材料。利用铝矾土尾矿和钾长石低温烧结制备莫来石质复相陶瓷，铝土矿尾矿的添加量高，制备工艺简单，成本较低；钾长石和锂瓷石加入可以降低烧结温度，减小能耗，还能提高产物的抗压强度和致密度。为铝土矿尾矿的综合应用提供的新的思路，具有深远的经济价值和环保意义。
