添加钛酸盐纳米线对陶瓷结合剂性能的影响
|
摘要
以CaO-Na_2O-B_2O_3-Al_2O_3-SiO_2体系为基础陶瓷结合剂,将水热温度150℃、保温24 h制备的一定量的钛酸盐纳米线加入其中,制得纳米陶瓷结合剂。通过电子多功能试验机、洛氏硬度计等对纳米陶瓷结合剂的抗折强度、硬度和流动性进行测试。结果发现:当纳米陶瓷结合剂中钛酸盐纳米线添加质量分数为1.0%、其烧结温度为610℃时,纳米陶瓷结合剂的抗折强度和硬度最大,分别为92.54 MPa和86 HRB,相比于基础陶瓷结合剂的61.09 MPa和53 HRB分别提高了51.5%和62.3%;且纳米陶瓷结合剂的流动性显著改善,气孔相对较少,生成的物质分布较为均匀,综合性能提高。
A certain amount of titanate nanowires prepared at hydrothermal temperature 150 ℃ and held for 24 hours were added into CaO-Na_2O-B_2O_3-Al_2O_3-SiO_2 system to prepare nano-ceramic binder.The flexural strength, hardness and fluidity of nano-ceramic binder were tested by electronic multi-functional testing machine and Rockwell hardness tester.The results show that when the mass fraction of titanate nanowires in nano-ceramic binder is 1.0% and the sintering temperature of nano-ceramic binder is 610 ℃, the flexural strength and hardness of nano-ceramic binder are 92.54 MPa and 86 HRB, respectively, which are 51.5% and 62.3% higher than 61.09 MPa and 53 HRB of basic ceramic binder. The fluidity of nano-ceramic binder is improved remarkably and the material distribution is more uniform with less pores. Therefore, the comprehensive performance is improved.
