Abstract

Abstract

A certain amount of titanate nanowires prepared at hydrothermal temperature 150 ℃ and held for 24 hours were added into CaO-Na₂O-B₂O₃-Al₂O₃-SiO₂ 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.
