电子陶瓷具有独特的介电性、压电性、磁性、半导体性、绝缘性等,在电容器、集成电路、电子元件等诸多领域具有广泛用途,在陶瓷工业中占据了重要地位。电子陶瓷依据性能,可分为绝缘陶瓷、介电陶瓷、压电陶瓷、磁性陶瓷和传感器陶瓷等,大多数陶瓷材料通常存在介电常数低、不耐高温、温度稳定性能差等缺陷,这主要和电子陶瓷本身组份以及制备工艺有重要关联。许多研究工作着力解决单一电子陶瓷材料组分存在的缺陷,例如CN101811863A报道了一种以二氧化钛为基料,添加稀土氧化物的高稳定电子陶瓷材料。
化学合成技术是一种将无机材料与有机材料进行组分及功能复合的有效技术,具有价格低廉、设备简易、复合多功能材料、适于批量生产等诸多优势,在制备复合材料中发挥着越来越重要的作用。
发明内容
本发明的目的在于:提供一种电子陶瓷复合材料的制备方法。结合化学合成技术,制备多组分、复合结构和性能的含氧化钛、氧化钬、氧化锰及氧化铝的电子陶瓷材料。
本发明的技术解决方案是:在一定量浓硫酸中,搅拌条件下,缓慢依次加入氧化钬及氧化锰,溶解后缓慢滴加有机钛醇盐,同时缓慢加入硫酸铝,搅拌条件下,缓慢加入分散剂木质素磺酸钠,剧烈机械搅拌,发生水解、聚合反应,制得溶液A,向其中加入碳酸钠溶液,调节pH值至中性,得到乳浊液B,经过滤得到湿滤渣C,经干燥得到粉末D,经热处理得到结构有序的电子陶瓷材料。
强酸性条件下,氧化钬及氧化锰溶解于浓硫酸中,获得金属钬离子Ho3+和锰离子Mn2+,有机钛醇盐溶解于浓硫酸中,获得-(Ti-O)n 2n+-阳离子,硫酸铝溶解于硫酸中获得铝离子Al3+,通过-(Ti-O)n 2n+-的桥架作用,连接Ho3+,Mn2+和Al3+,在木质素磺酸钠的分散作用下,通过化学键合作用,即-Ti-O-Ho-O-,-Ti-O-Mn-O-,以及-Ti-O-Al-O-,形成TiO2-Ho2O3,TiO2-MnO和TiO2-Al2O3金属复合物。
本发明与现有技术相比,其显著优点:通过化学工艺合成,设备简易、成本低廉,制备了多组分、多功能的电子陶瓷材料。
