Water-based binder system enables fast ceramic molding. (Forming/Processing).

A novel binder made of water and agar for injection molding ceramics has been developed by Honeywell, Morristown, N.J. Water rather than conventional alcohol or carbonates in the binder system is said to eliminate the need for binder absorbents, and results in the emission of harmless moisture in the drying phase. Water also serves the dual function of solvent and carrier. It helps keep the binder liquid enough for injection, while also acting as the carrier for the ceramic mixture. Any excess liquid can be pre-evaporated prior to molding to achieve the proper viscosity. This ...
