将本发明实施例1-5制备的产品进行X射线衍射测试,测试结果如图1所示,从图1中可以看出实施例1、实施例2、实施例3和实施例4得到的产品为Ti3AlC2/莫来石复合陶瓷,实施例5中得到的产品Ti3AlC2与莫来石发生了反应;将本发明实施例1-5制备的产品进行致密性测试,测试结果如图2所示,实施例1-5制备得到的产品致密度均大于65.92%,最高可达88.83%;将本发明实施例1-5得到的产品进行导热性测试,测试结果如图3所示,从图3中可以看出,实施例1-5制备得到的产品导热率均大于16.43W/(m·K),最高可达21.90W/(m·K);如4-8为本发明实施例1-5所制备产品的扫描电镜图;如图4-8所示,随着莫来石体积分数增大,Ti3AlC2/莫来石复合陶瓷的导热率将会越高,耐热性增强;但是复合陶瓷内部孔洞明显增多,致密度明显下降,力学性能也降低,抗热震性也会有所下降,使用寿命缩短。
在作为生产玻璃制品托板之前,通常先对其表面进行粗磨、细磨和抛光,再进行高温热暴露氧化处理,使其表面生成一层厚厚的TiO2和Al2O3致密氧化膜,从而具有低的玻璃润湿性,同时抗氧化性能和热稳定性能也得到加强;将实施例中制备的复合陶瓷用于生产玻璃制品试验,从实施例1-5所得产品的结果进行分析,实施例1中制备的产品将玻璃和Ti3AlC2/莫来石复合陶瓷分开比较困难,将会损坏玻璃制品;实施例2中将玻璃和Ti3AlC2/莫来石复合陶瓷分开比较容易;实施例3中将玻璃和Ti3AlC2/莫来石复合陶瓷分开也比较容易;实施例4中将玻璃和Ti3AlC2/莫来石复合陶瓷分开比较容易,但是可以看到Ti3AlC2/莫来石复合陶瓷上粘结有少量玻璃;实施例5中将玻璃和Ti3AlC2/莫来石复合瓷分开很困难,可以看到Ti3AlC2/莫来石复合陶瓷上粘结有大块玻璃,将会损坏玻璃制品。
从上述试验结果来看实施例2和实施例3中制备的Ti3AlC2/莫来石复合陶瓷可以完全替代从日本进口的氧化铝-莫来石陶瓷托板,不仅能延长陶瓷托板的使用寿命,而且可以降低生产成本,可以在玻璃厂广泛应用。
本发明Ti3AlC2/莫来石复合陶瓷是一种新型耐热复合陶瓷材料,兼具Ti3AlC2和莫来石的优点,具有很好的制备烧结性能,较高的耐热性和耐热震性,以及较低的导热率,适合作为陶瓷托板应用于生产玻璃制品,可以在高温下重复使用,达到工业化生产玻璃制品的要求。
文中钛三铝碳二/莫来石复合陶瓷即表示Ti3AlC2/莫来石复合陶瓷。
