<p>A method for degreasing a formed product from a powder, characterized in that it comprises immersing a formed product from a ceramic powder or a metal powder containing a binder comprising two or more components in an extracting liquid comprising an aqueous solution of a surfactant, thereby extracting selectively at least one component from the formed product to remove it, and then removing the residual components of the binder from the formed product. The method allows a speedy degreasing treatment in a short time with the suppression of occurrence of defects such as cracks, and can be practiced with high safety to a human body and the environment and further using inexpensive facilities.</p> |
