Producing standard sample to calibrate analysis devices to determine non-metallic inclusions in metals, comprises mixing powdered metal- and powdered non-metallic solid particles and then hot isostatically pressing in inert gas atmosphere

The method comprises mixing powdered metal particles (2) and powdered non-metallic solid particles (1) with one another and then hot isostatically pressing (6) in an inert gas atmosphere, so that the metal forms a matrix for the non-metallic solid particles. The powder mixture (3) made of metal particles and non-metallic solid particles is subjected to a temperature treatment (5) in a reducing atmosphere from hydrogen or mixtures of hydrogen with inert gases, noble gases, methane and/or other volatile alkanes before hot-isostatic pressing, and is precompressed to a porous blank. The method comprises mixing powdered metal particles (2) and powdered non-metallic solid particles (1) with one another and then hot isostatically pressing (6) in an inert gas atmosphere, so that the metal forms a matrix for the non-metallic solid particles. The powder mixture (3) made of metal particles and non-metallic solid particles is subjected to a temperature treatment (5) in a reducing atmosphere from hydrogen or mixtures of hydrogen with inert gases, noble gases, methane and/or other volatile alkanes before hot-isostatic pressing, and is precompressed to a porous blank, which is subjected to the temperature treatment. The maximum temperature during the temperature treatment is smaller than a melting point temperature of the metal powder forming the matrix. The blank is exactly pressed into a capsule, which has a bore in the capsule wall. The metal particles and non-metallic solid particles have grain sizes. The metal powder is steel powder. An independent claim is included for a standard sample for the calibration of analysis devices for determining non-metallic inclusions in metals. Die Erfindung betrifft ein Verfahren zur Herstellung einer Standardprobe für die Kalibrierung von Analyseeinrichtungen zur Bestimmung von nichtmetallischen Einschlüssen in Metallen, bei welchem pulverförmige Metallpartikel und pulverförmige nichtmetallische Feststoffpartikel miteinander vermischt und heißisostatisch in einer Inertgasatmosphäre gepresst werden, so dass das Metall eine Matrix für die nichtmetallischen Feststoffpartikel bildet. Die Aufgabe, ein Verfahren zur Herstellung einer Standardprobe für die Kalibrierung spektrometrischer Analyseeinrichtungen zur Bestimmung von nichtmetallischen Einschlüssen in Metallen vorzuschlagen, mit welchem lagerstabile Standardproben mit einem gezielt einstellbaren Anteil an nichtmetallischen Einschlüssen in einer metallischen Matrix hergestellt werd
