摘要:
In order to achieve the object of providing a mixture by means of which, in particular, sintered moldings can be obtained that are virtually free of surface stains produced by soot particles, a mixture is proposed which comprises at least one pressing aid and at least one additive, wherein the additive is selected from a group of substances which have releasable carbon dioxide.

The aim of the invention is to devise a binder that is an alternative to prior art binders for producing sintered molded articles. Said aim is achieved by a binder comprising a first substance that has a first melting point and a first vapor pressure at 80° C and a second substance that has a second melting point and a second vapor pressure at 80° C, the maximum melting point of the first and second substance amounting to about 150° C, and the minimum vapor pressure of the first and second substance amounting to about 5 torr (667 Pa) at 80° C.
