Abstract
The invention relates to a mixture of two particulate phases which is used in the production of a green compact that can be sintered at higher temperatures. According to the invention, A) the first phase contains particles that consist of a metal and/or a metal alloy and/or a metal compound, and B) the second phase contains particles from the group of the inorganic compounds which do not release any decomposition products at temperatures of more than 400 °C that are interstitially soluble in the sintering metal phase and/or that react with said phase to stable compounds. The inventive mixture, by providing the second phase, is effective in supporting the fine structure of the first phase against the forces of surface tension during the sintering process. During sintering, the second phase remains thermally stable and substantially chemically inert with respect to the first phase.
