A good overview of each slurry's component on green and sintered properties of the casted tape. Pros of organics are low boiling temperature, it prevents powders from hydration, but evaporation in the open systems harden work. Water-based systems slow down evaporation, often leading to agglomeration of the powder. PVA as a binder increases tensile strength but decreases green density. Glycerine as a plasticizer enhances flexibility & decreases tensile strength & drying shrinkage.
