铝硅酸盐对粘结剂喷射成形氧化铝基陶瓷性能的影响
Effect of Aluminosilicate on the Properties of Alumina-Based Ceramics Formed by Binder Jetting
摘要
Abstract
Binder jetting(BJ)technology offers advantages such as rapid forming,high material utilization,and relatively low cost,holding significant potential for the rapid fabrication of ceramics.However,ceramic specimens produced by this method typically require infiltration treatment followed by sintering to enhance the mechanical strength.To simplify this process and enable the as-printed ceramic green bodies to achieve high strength through direct sintering,this study mixed aluminosilicate powder with alumina powder,and prepared alumina-based ceramic samples without the infiltration step.The effects of aluminosilicate content,sintering temperature and holding time on the properties of the alumina-based ceramics were investigated.The results show that when the aluminosilicate powder mass fraction is 40%and the sintering temperature is 1 500 ℃,the alumina-based ceramic achieves a flexural strength of 10.50 MPa,representing a fivefold increase compared to samples without aluminosilicate addition,and the dimensional shrinkage along Z axis under these conditions is only about 7.5%.Using this sub-optimized process,alumina-based ceramic samples with relatively high precision can be successfully fabricated.关键词
