Cold sintering of ZnO using crystalline zinc acetate dihydrate in the absence of added water is examined. Prior studies use an aqueous solvent, usually containing a weak acid, base, or organic salt, as the mass transport phase during cold sintering. This paper shows equivalent densification of ZnO using solid, powdered acetate as …
Detailsinvolving sintering, whether it is injection moulding, isostatic pressing, hot pressing, powder compaction or slipcasting, organic binders are used to hold powders together. For powder compaction organics are also added in the form of lubricants – small fatty acid based materi-als such as Acrawax® or zinc stearate used for die wall
