High-strength ceramic mainly prepared from tungsten tailings and preparation method of high-strength ceramic
The invention provides high-strength ceramic mainly prepared from tungsten tailings and a preparation method of the high-strength ceramic. The high-strength ceramic comprises the following raw materials in percentage by mass: 80%-90% of tungsten tailings, 10%-20% of albite and 1%-5% of a binder. The preparation method comprises the following steps: firstly preprocessing the tungsten tailings, mixing the preprocessed tungsten tailings with albite, carrying out ball milling, and carrying out compression molding by virtue of a stainless steel mold; sintering after drying, so as to obtain the high-strength ceramic. The high-strength ceramic has the coefficients that the volume density is 2.42g/cm<3>-2.47g/cm<3>, the water absorption rate is 0.018%-0.089%, the bending strength is 78MPa-105MPa, and the compressive strength is 170MPa-252MPa. The preparation method has the beneficial effects that the utilization rate of the tungsten tailings is high (the mass percent is 80%-90%); by combining the tungsten tailings with a traditional raw material, namely albite, the sintering temperature is substantially decreased; the preparation process is simple, and the production cost is relatively low; the preparation method is suitable for large-scale production, and the environmental pollution caused by the tungsten tailings can be effectively reduced.
