Ceramic with high thermal shock resistance and preparation process thereof
The invention discloses ceramic with high thermal shock resistance and a preparation process thereof, and belongs to the technical field of ceramic preparation. In order to solve the problem of how to further improve the thermal shock resistance of the ceramic, the thermal shock resistant ceramic is prepared from the following components in percentage by mass: 40-50% of blank raw mud powder, 5-15% of aluminum oxide powder, 4-8% of micron-sized cerium oxide, 3-5% of nano-sized cerium oxide and 30-40% of a solvent, and during preparation, the blank raw mud is cut into blocks to obtain mud blocks; after the mud blocks are dried, the mud blocks are smashed, and blank raw mud powder is obtained; then adding various raw materials into a wet-process ball mill for ball milling; then adding nanoscale cerium oxide into the wet-process ball mill for continuous ball milling to obtain a premix; adding the premix into a plaster mold, and obtaining a blank after the premix is dried and plasticized; and sintering the dried and plasticized blank body to obtain the ceramic product. By controlling the particle sizes of the added micron-scale cerium oxide and nano-scale cerium oxide, the obtained ceramic is compact in structure, and the thermal shock resistance of the ceramic is improved.
本发明公开了一种高抗热震性陶瓷及其制备工艺，属于陶瓷制备技术领域。本发明如何进一步提高陶瓷的抗热震性的问题，本发明以质量百分比计，包括以下组分：40‑50％的坯料原泥粉末、5‑15％的氧化铝粉末、4‑8％的微米级氧化铈、3‑5％的纳米级氧化铈、30‑40％的溶剂，制备时将胚料原泥切成块状得到泥块，待泥块干燥后对泥块进行粉碎，得到坯料原泥粉末；然后将各种原料加入到湿法球磨机中进行球磨；然后将纳米级氧化铈加入到湿法球磨机中继续球磨，得到预混料；将预混料加入到石膏模具中待其干燥塑性，得到胚体；对干燥塑性后的胚体进行烧结，得到陶瓷制品。本发明通过控制添加的微米级氧化铈和纳米级氧化铈的粒径，使得到的陶瓷结构致密，提高了陶瓷的抗热震性。
