多孔氧化物陶瓷的可控烧结制备及性能研究

, 2017
多孔陶瓷具有耐高温、抗酸碱、耐有机腐蚀、良好的生物惰性、使用寿命长、再生性能好等优点，广泛应用在过滤、隔热、吸音及生物骨骼等领域中。目前，多孔陶瓷制备所用的原料多为形貌不规则的颗粒，这些颗粒在烧结过程中的可控性差，存在不均匀的团聚收缩，导致陶瓷中出现死孔、半通孔，并伴随孔率的烧结损失，影响了多孔陶瓷的实际应用效果。本论文针对陶瓷孔结构难以调控的问题，提出采用热等离子体制备的球形致密颗粒进行堆积造孔，通过烧结，球形颗粒间的接触点形成颈部连接，获得孔结构均匀、贯通、可调的多孔陶瓷。主要工作为：(1 ...

具有低连接温度高弯曲强度的碳化硅陶瓷连接材料以及连接碳化硅陶瓷的方法

, 2017
本发明提供了一种具有低连接温度高弯曲强度的碳化硅陶瓷连接材料，该连接材料为钛膜，并且所述的钛膜厚度小于1微米。将该连接材料夹置在待连接碳化硅陶瓷材料之间，通过外部热源加热连接界面将待连接的SiC材料连接在一起，降低了外部热源的热量供给，具有连接温度低的优点，有利于节约成本，降低工业化生产难度；同时 ...
