Tungsten granulates are mainly used in the analysis of the infrared carbon and sulfur oxide flux combustion samples, help to reduce the sample melting point and improve the release of carbon and sulfur. Used for producing tungsten products, contact alloy, large proportion alloy, hard alloy, alloy additive, etc. tungsten carbide crashed particle is commonly used for the wear resistance and grinding industrial.
Tungsten metal particles for the oxidation flux of infrared carbon and sulfur analyzer, burning samples, help to reduce the sample melting point, to improve the release of carbon and sulfur. The specification of the tungsten granulates are: -20—40. Tungsten is non-ferrous metals, the important strategic metal tungsten. The tungsten content in the earth's crust is 0.001%. 20 kinds of tungsten minerals are been found until now.
In general,Tungsten deposits are along with the activity and the formation of granitic magma. The tungsten is silver-white lustrous metal, with high melting point .The chemical component are:W≥99.9%,O≤0.050,C≤0.0010,S≤0.0010.
