Technical Parameters

Product performance

        Nanometer carbonized vanadium VC=62.95, including the carbon 22% is the ferrous metal shape powder, is the sodium chloride cubic system the crystallization, crystal constant 4.182 Egypt, the melting point 2800℃, the boiling point 3900℃, has the good chemical stability and the high temperature performance. May use in the cutting tool, the steel-making industry and the tungsten base hard alloy grain refining medicinal preparation, can enhance the alloy performance obviously.

        As suppresses the alloy crystal grain growth and the improvement organizational structure VC which increases for the main application and so on rare metal carbide, no matter is produces the macrograin like mine tool or the dowel and so on ultra-fine grain alloy, should choose Fei the granularity low rare metal carbide, because increases the rare metal carbide is micro, it is only adjusts the WC granularity and the improvement organizational structure function, thus, hoped that the chemical additive thinner dispersion effect is better the line. Especially to the dowel and so on ultra-fine grain alloy, if the chemical additive is excessively thick, instead will form the alloy to clamp thickly, will not be suitable enhances the material the performance. Our company sells the nanometer carbonized vanadium powder body, the granularity achieve a nanometer level extremely, the increase proportion to one may enhance the material large scale generally the performance.

        The carbonized vanadium has widely applied as the grain refining medicinal preparation in professions and so on steel and iron, along with the technical development, after the high purification, the nanometer nanometer carbonized vanadium, its application obtains further expansion, has applied massively in the hard alloy and the catalyzed material and so on numerous domains, is a kind of union vanadium titanium resource development production kind of important high added value new material.

Application direction

        Cutting tool, the steel-making industry and the tungsten base hard alloy’s grain refining medicinal preparation, can enhance the alloy performance obviously.

Storage conditions
