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: irregular or spherical powder morphology with tight control of particle size distributions (PSDs); high reproducibility; and outstanding purity levels.
We can customize key particle properties based on unique customer specifications and can generate quantities from the lab-scale up to high volume automated manufacturing. Additionally, the H.C. Starck Solutions team is available to assist with R&D services for custom high-performance powders and alloys.
World-class application technology and laboratory services enable us to tightly control the processing parameters for a range of refractory metals. This forms the backbone of our customer-centric high-performance powder design capabilities, servicing applications as varied as:
- Additive Manufacturing
- Brake Pads
- Ceramic Metallization
- Chemical Catalysts
- Detonation Initiators
- Diamond Tooling
- Heating Elements
- Metal Injection Molding
- Metal Matrix Composites
- Pressed and Sintered Ingots
- Pressed and Sintered Shapes
- Thermal Spray Technology
- Sputtering Targets
- X-ray anodes
We offer a wide variety of high-performance molybdenum powders in the size and purity to match any customer‘s requirements, from extremely fine metal injection molding powder (MIMP) to flowable ready-to-press powder (RTP). Our expansive powder production capabilities mean we can meet stringent specifications, and offer a wide range of molybdenum alloys, such as TZM (Mo-0.5Ti-0.1Zr) and MHC (Mo-1.2Hf-0.1C), or oxide dispersion strengthened alloys such as MoLa (Mo-1.0La2O3).
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.
The physical and chemical properties of the powders can be adjusted to meet individual customer requirements. Typical purity exceeds 99.95%. Standard screens sizes of -5 to -325 mesh are available, with finer sizes down to -635 mesh available on lab scale quantities. Split screen fractions such as -100+325 mesh are also available. The oxygen content can be offered at lower levels through special reduction conditions as well as special packaging to protect the powder.

Thermal Spraying with Mo Powders
Innovation is the key to H.C. Starck Solution’s success in developing the highest quality molybdenum powders for thermal spray applications. Our molybdenum thermal spray powders are spherical, flowable and designed to extend the life of products by repairing worn and damaged surfaces, and protecting against the detrimental effects of erosion, wear and corrosion. Our thermal spraying powders involve the disposition of powders covering a substrate forming an even coating of contiguous layers.
Diverse Spraying Processes:
- High velocity air fuel (HVAF)
- High velocity oxy-fuel coating spraying (HVOF)
