Composite corundum ceramic and preparation method thereof
The invention particularly relates to composite corundum ceramic and a preparation method thereof, and belongs to the field of high-temperature structural materials. The composite corundum ceramic is prepared from the following raw materials: zircon powder, white corundum, alumina whiskers and a binder. White corundum serves as a matrix, zircon powder with different mass fractions is added to serve as a composite corundum ceramic system, and a traditional high-temperature ceramic system is broken through. White corundum and zircon powder are used as raw materials, a dry pressing forming process is utilized, the preparation process is simple, the cost is saved, and the preparation process is green, environment-friendly and pollution-free. The composite corundum ceramic is prepared under a high-temperature aerobic condition by utilizing a muffle furnace low-temperature co-sintering technology, so that a traditional preparation method of high-temperature ceramic is broken through; the prepared composite corundum ceramic has higher use temperature, good ablation resistance and long service life, and the application range of the material is widened.
本发明具体涉及一种复合刚玉陶瓷及其制备方法，属于高温结构材料领域。该复合刚玉陶瓷通过以下原料制备而成：锆英粉、白刚玉、氧化铝晶须和粘结剂。本发明以白刚玉为基体，添加不同质量分数的锆英粉作为复合刚玉陶瓷体系，突破了传统高温陶瓷体系。本发明利用白刚玉和锆英粉作为原料，利用干压成型工艺，制备工艺简单，节约成本，制备过程绿色环保无污染。本发明利用马弗炉低温共烧结技术，在高温有氧条件下制备复合刚玉陶瓷，打破了传统高温陶瓷的制备方法；制备的复合刚玉陶瓷具有更高的使用温度，耐烧蚀性能好、使用寿命长、拓宽了材料的应用范围。
