Abstract:
A method of injection molding inorganic particles having a size from 0.1 to 0.6 mm comprising the steps of:a) spray drying the inorganic particles;b) mixing the spray dried inorganic particles with a binder system to form a compounded material, said binder system consisting of organic binder, oleic acid and a linear C.sub.11, alcohol ethoxylate nonionic surfactant;c) injecting the compounded material at a pressure of 10 to 70 psi and an injection temperature of 80.degree. C. to 85.degree. C. into a mold to form a green part;d) debinding the green part to remove most of the binder system; ande) sintering the debined green part to form the final molded part.
