Oversized high-alumina ceramic ball and preparation method thereof
The invention belongs to the field of ceramic materials, and particularly relates to an oversized high-alumina ceramic ball and a preparation method thereof. The oversized high-alumina ceramic ball is prepared from the following components by mass: 90-96% of Al2O3 powder, 2-6% of CaCO3 powder, 1-3% of SrO2 powder and 0.5-2% of kaolin. The preparation method of the oversized high-alumina ceramic ball comprises the steps of ball milling, agent adding and stirring, high-position injection molding, fettling, microwave drying, high-temperature sintering and polishing. According to the invention, the preparation process is simple, the requirement for equipment is low, and the prepared high-alumina ceramic ball is large in size, compact in matrix, free of holes, smooth and clean in appearance, free of defects such as spots, bubbles and adhesion damage, not prone to cracking in the drying and sintering process and high in yield.
本发明属于陶瓷材料领域，具体涉及一种超大尺寸高铝瓷球及其制备方法。所述超大尺寸高铝瓷球的组分包括Al2O3粉、CaCO3粉、SrO2粉、高岭土，按照质量百分比计，所述Al2O3粉含量为90~96%，所述CaCO3粉含量为2~6%，所述SrO2粉含量为1~3%，所述高岭土含量为0.5~2%。超大尺寸高铝瓷球的制备方法包括球磨、加剂搅拌、高位注模成形、修坯、微波干燥、高温烧结、打磨。本发明制备工艺简单，对设备要求低，制备的高铝瓷球尺寸大，基体致密无孔洞，外观光洁，无斑点、气泡、粘损等缺陷，干燥及烧结过程中不易开裂，成品率高。
