Effects of different backbone binders on the characteristics of zirconia parts using wax-based binder system via ceramic injection molding
Abstract In this work, various backbone binders were used in wax-based binder system to formulate zirconia parts by ceramic injection molding (CIM). The effect of different backbone binders on the molding, debinding, and sintering behaviors was investigated. After blending process, the feedstock usi...
