ABSTRACT The new inorganic colloid is a particle-free decomposable binder that can solve the nozzle clogging problem and precipitate zirconia particle upon heating. The inorganic colloidal binder can be used as a binder precursor to replace commonly used PVP binder in printing ZrO2 ceramics parts using binder-jet technology. Green bodies were printed using inorganic colloid binders with different saturation level and PVP binder separately, then cured and sintered. The effects of binder saturation level and sintered temperature on the properties of the green and sintered bodies were investigated. After being deposited into the powder bed interstices and cured, the inorganic colloidal binder containing zirconium basic carbonate decomposes and forms ZrO2 ceramic particles that are filled the interstices and sintered to provide bonding strength to the printed parts. Samples with inorganic colloidal binder eventually perform better surface quality and denser sintered body than polymer binder when using same saturation ratio.

以无机胶体为粘合剂的粘合剂喷射氧化钇稳定氧化锆陶瓷

摘要 新型无机胶体是一种无颗粒的可分解粘合剂，可解决喷嘴堵塞问题并在加热时沉淀氧化锆颗粒。无机胶体粘合剂可用作粘合剂前体，以替代常用的 PVP 粘合剂，用于使用粘合剂喷射技术打印 ZrO2 陶瓷部件。分别使用不同饱和度的无机胶体粘合剂和 PVP 粘合剂印刷生坯，然后固化和烧结。研究了粘结剂饱和度和烧结温度对生坯和烧结体性能的影响。沉积到粉床空隙中固化后，含有碱式碳酸锆的无机胶体粘合剂分解形成ZrO2陶瓷颗粒，填充空隙并烧结，为印刷部件提供粘合强度。当使用相同的饱和比时，使用无机胶体粘合剂的样品最终比聚合物粘合剂具有更好的表面质量和更致密的烧结体。
