Quality-Assured High-Performance Powders
H.C. Starck Solutions quality-assured materials development and processing capabilities ensure that high-performance powders can be generated to specific customer requirements with exceptional material properties. This includes: uniform, spherical powder morphology with tight control of particle size distributions (PSDs); exceptional flowability; high reproducibility; and outstanding purity levels.
Tungsten metal powders are produced by reducing tungsten oxides (WOx) in a controlled hydrogen atmosphere. Tight control of process temperature, humidity, and additional dopants enables H.C. Starck to finely tune the coarseness of tungsten high-performance powders before additional carburization processes occur. This enables a diverse range of powder grades with average Fisher grain sizes across an approximate range of 0.7—50 micrometers (µm). H.C. Starck Solutions molybdenum powders are similarly produced in a hydrogen atmosphere, using molybdenum trioxide (MoO3) and ammonium molybdates. This is a finely-tuned process that enables the generation of high-performance molybdenum powders with a mean particle size of 20—30 µm.
World-class application technology and laboratory services enable H.C. Starck Solutions to tightly control the processing parameters for a range of refractory metals. This forms the backbone of H.C. Starck Solutions customer-specific powder design capabilities. If you would like to learn more, simply contact a member of the team today.
