| description | The coal slime is adopted as the raw material, the coal slime raw material is smashed through the ball mill, then the quartz sand is added for mixing, then dry pressing forming is conducted, sintering is conducted in the argon atmosphere, the Al2O3-SiC composite ceramic is obtained, the purpose of preparing high-technology ceramic through the coal slime is achieved, the high-technology-content additional value of the coal slime is effectively improved, and the process is simple. The prepared composite ceramic has high strength, and the harm of the coal slime to the environment is reduced.
本发明采用煤泥作为原料，利用球磨机将煤泥原料进行粉碎后添加石英砂进行混料，随后干压成型氩气气氛下烧结得到Al2O3-SiC复相陶瓷，实现了利用煤泥制备高技术陶瓷目的，有效提升了煤泥高技术含量附加值，工艺简单，制备得到的复相陶瓷具有较高强度，减少了煤泥对环境危害。 |
