Abstract: THE INVENTION RELATES TO A PROCESS FOR PREPARING SULPHURATED PRODUCTS CONTAINING AT LEAST TWO METALS AND WHICH IS SELECTED FROM THE GROUP CONSISTING OF THIOCHROMITES, THIOVANDITES AND THIOTITANATES OF MONO- AND DIVALENT METALS, OF SOLID SOLUTIONS OF SIMPLE AND MIXED SULPHIDES OF TRANSITION METALS AND METALLIC OXISULPHIDES, WHICH COMPRISES HEATING PROGRESSIVELY THERMICALLY DECOMPOSABLE COMPOSITIONS CONTAINING THE METALLIC ATOMS UNDER THE SAME RATIO AS IN THE END PRODUCTS IN AN HYDROGEN SULPHIDE CONTAINING ATMOSPHERE, TO A PREDETERMINED TEMPERATURE RANGING FROM 200 TO 1000*C. AND MAINTAINING THE HEATED PRODUCT AT SAID PREDETERMINED TEMPERATURE UNTIL THE CONTENT IN OXYGEN, IF ANY, OF THE HEATED PRODUCT HAS BECOME SUBSTANTIALLY CONSTANT.
