The research of molten Salt Synthesis of Chromium Carbide (Ò») Abstract: The molten salt synthesis is a novel synthetic method to Synthesize inorganic material powders .The method adopts one or more of the low melting point of the salt melt as a reaction medium, utilizes the dissolved reaction in molten salt to implement the reaction of molten salt in full access, in order to achieve lower temperature and improve reaction speed . (Cr3C2), belonging to cermet , is a high melting temperature (2143 K) of inorganic material with good wear and corrosion resistance and anti-oxidation . Chromium Carbide is used in a great quantity as additives for welding additives, cemented carbide industry , and metal surface protection of the thermal spraying materials, because of special properties of high temperature. In this article , chrome oxide powder and Carbon Black were used as the main raw material to Synthesize chromium carbide ,using the method of the molten salt synthesis .The experimental results show that the optimum technological parameters of synthesizing chromium carbide are , 1200¡æ¡Á5h (under the MSS of 2©U1) and 1250¡æ¡Á3h (under the MSS of 4©U1) Key words: chromium carbide; molten salt synthesis; MSS |
