Obiettivo The basic aims of the project have been achieved: binder components soluble in supercritical CO2 have been identified and used to produce moulding mixes; binder additives, such as viscosity modifiers and surface active agents, have been identified and used to optimise the moulding mixes particularly to increase the powder loading to a maximum; the techniques for the supercritical extraction of injection moulded components have been established and a code of practice developed; components have been successfully moulded, extracted and sintered in a range of ceramic materials; recycling of the binder has been shown to be feasible making this a clean technology; the cost of using supercritical extraction has been shown to be about double that of thermal debinding.The industrial objective of this project is the development of supercritical solvent extraction as an economic and environmentally -safe alternative to binder removal from injection-moulded ceramics by thermal debinding. The technical objective is to develop injection-moulding binder systems adapted to coarse,fine and nano-sized ceramic powders and adapted to a superficial solvent debinding process,which will be developed and optimised during the project.The principal phases of the project to achieve these objectives are as follows.The identification and characterisation of molecular weight hydrocarbons which are soluble in supercritical CO2 and can be used as binders to make injection moulding mixes. The development of new binder systems adapted to supercritical solvent extraction. The preparation and moulding of injection moulding mixes with coarse,fine and nano-sized ceramic powders. The development and optimisation of a supercritical solvent extraction using the moulded pieces and the determination of the properties and quality of the extracted and sintered pieces. A comparison of the economics of the supercritical solvent debinding process with conventional thermal debinding.
