Tungsten granules, also known as tungsten flux, are made by breaking forged tungsten parts.
The standard specifications are typically 12-20 mesh, 20-40 mesh, and 40-60 mesh, with a sulfur content not exceeding 0.0005% and a carbon content not exceeding 0.0008%.
Due to their low impurity content and high melting point, tungsten granules are often used as catalysts in carbon-sulfur analyzers, significantly enhancing the precision and accuracy of measurement values.
