Tungsten filters
Brožek, Vlastimil ; Matějíček, Jiří ; Neufuss, Karel
Spheroidized tungsten powder was sintered by HIP and BELT methods at 1750°-1950°C. Sintering temperature and sintering pressure, which controls the pore distribution in final products, was optimized by increased hardness of tungsten particles through the formation of unreacted WC ore W2C core. Porosity and permeability of tungsten filters, which application is foreseen in high temperature filtration of metals and melts inorganic substances were measured.
