Abstract: The invention relates to an iron-based powder composition which, in addition to a substantially non-alloyed Fe-powder, comprises Sn and P, optionally lubricant and at most 1.0 % by weight of impurities. In the composition, Sn and P are present as an SnP-alloy in powder form, or else Sn is present in the form of a metallic powder and P is present in the form of a ferrophosphorous powder, the Sn-content, based on the total iron-based powder composition, being at least 4.5 % by weight, and the individual particles, which contain Sn and P, being present as particles substantially separate from the particles in the non-alloyed Fe-powder. Finally, Sn and P may also be present as an SnP-alloy in powder form, and Sn may also be present as a metallic powder. This composition may optionally also contain P as a ferrophophorous powder.

Abstract: Process of preparing an inhomogenous sintered body by adjoining metal powder with refractory ceramic powder at normal powder metallurgical pressures and sintering conditions. The invention is characterized thereby that the sintered body is manufactured in one layer or several layers displaced mixing ratio between the ceramics and the metal and that the binding between ceramics and metal is strengthened with monoaluminium phosphate or a monoaluminium phosphate former. The sintered body can be used for example as heat shielding.
