Tungsten flux, also known as tungsten particles, is a granular substance made of high-purity tungsten metal (usually purity ≥99.95%). It has a silver-gray or light-gray polyhedral structure and has the characteristics of high density, high melting point, high hardness, corrosion resistance, strong conductivity and small thermal expansion coefficient. It is generally used as a flux in carbon-sulfur analyzers to analyze the carbon and sulfur content in steel, alloys, ceramics, minerals and other inorganic substances. Tungsten flux can promote the melting…
