Method for preparing boron carbide anti-damage ceramic engineering material 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 boron carbide anti-damage ceramic engineering material from coal solid waste or bauxitesolid waste. The material is prepared from the following raw materials in parts by weight: 5-40 parts of a combustion-supporting catalyst, 25-75 parts of aluminum oxide, 20-30 parts of boron carbideand 1.5-3 parts of a reinforcing agent. The preparation method comprises the following steps: mixing the raw materials in parts by weight, carrying out ball milling, drying at 100-150 DEG C for 1 hour, granulating, forming a blank under pressure, drying again, and carrying out primary sintering at 1100 DEG C and secondary sintering at 2200 DEG C to obtain the ceramic engineering material. The preparation method disclosed by the invention has very considerable economy and convenient operability. The ceramic engineering material has the following advantages: 1, the hardness is high, HV is 1500-3500, and the HRC of the prepared composite functional ceramic exceeds a measurement meter range; 2, the material is outstanding in high-temperature strength and low in thermal conductivity, and can beused for manufacturing heat insulation parts; 3, the material is excellent in wear resistance; 4, the material is low in density and small in mass; and 5, the material is excellent in corrosion resistance, and has a wide application value.
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碳化硼防毁伤陶瓷工程材料的方法；由以下重量份配比的原料制备而成：助燃催化剂5‑40份、氧化铝25‑75份、碳化硼20‑30份、增强剂1.5‑3份；上述重量份配置的原料混合球磨，然后100℃～150℃1h烘干，制粒、压力成胚、再次烘干，经过1100℃一次烧结和2200℃二次烧结后得到陶瓷工程材料；本发明制备方法具备十分可观的经济性与便捷的操作性；本发明陶瓷工程材料具有以下优势：1、硬度高；HV>1500~3500;我们制备的复合功能陶瓷HRC超出测量表程；2、高温强度突出及导热率低，可以被用来制造隔热零部件，3、耐磨性能优越，4、密度低、质量小，5、耐腐蚀性能极佳，具有广泛的应用价值。
