Stable aqueous iron based feedstock formulation for injection molding

摘要

A composition for forming molded metal containing articles having improved stability. More particularly, a corrosion resistant composition for forming injection molded articles having a sodium silicate corrosion inhibiting additive. The corrosion inhibitor prevents metal oxidation when a metal containing powder is mixed with a water based binder, providing stability to the article and preventing generation of hydrogen gas. This significantly enhances the shelf life of the moldable composition prior to molding.
