Abstract

L'invention porte sur un fondant à plusieurs composants pour l'analyse de teneurs en carbone et en soufre dans des échantillons métalliques ou non métalliques, ainsi que sur son procédé de préparation. Un fondant à plusieurs composants est composé (en partie en poids) : de 1,5 à 2 parties de tungstène (W), de 0,3 à 1 partie de fer (Fe), de 0,1 à 0,3 partie d'étain (Sn), de 0,1 à 0,5 partie de V2O5; et un autre fondant à plusieurs composants est composé (en partie en poids) : de 1,5 à 2 parties de tungstène (W), de 0,3 à 1 partie de fer (Fe), de 0,1 à 1 partie de cuivre (Cu), la matrice de matière poreuse métallurgique en poudre étant constituée de tungstène et de fer, et l'étain ou le cuivre peut être fondu, peut pénétrer dans les trous de la matrice poreuse et rester dans celle-ci. Les fondants à plusieurs composants présentent de bonnes caractéristiques en termes d'uniformité et de fusibilité et peuvent être ajoutés en une fois avec une moindre possibilité d'erreur en ce qui concerne la quantité de l'ajout et avec moins de poussière de poudre produite par la cuisson, ce qui améliore considérablement la précision de l'analyse du carbone et du soufre.
