Abstract:
A method for forming and shaping a plasticized powder mixture comprising:compounding together an inorganic powder component consisting of a sinterable inorganic particulate material mire, and a binder system comprising a binder, a solvent for the binder, a surfactant, and a component which is non-solvent with respect to at least the binder and solvent components and which exhibits a lower viscosity than the solvent when containing the binder, at least a portion of the non-solvent comprising an organic liquid having a 90% recovered distillation temperature of no greater than about 225.degree. C.;mixing and plasticizing the inorganic powder and the binder system components to form a plasticized mixture; and,shaping the plasticized mixture to form a green body.
