1. Fundamental Properties
Tungsten powder is derived from tungsten ores (e.g., wolframite, scheelite) via chemical processing. It boasts exceptional thermal stability with a melting point of 3422°C and a density of 19.3 g/cm³. Available in particle sizes ranging from sub-micron (0.5–1 μm) to coarse powder (50–100 μm), its purity typically ranges from 99.9% to 99.999%.
2. Production Process
The primary production route involves Ammonium Paratungstate (APT) Reduction: APT is calcined to tungsten trioxide (WO₃), then reduced in a hydrogen atmosphere through multi-stage heating (500–800°C). For ultra-fine powder, plasma spraying or chemical vapor deposition (CVD) is employed. Coarse tungsten powder is produced via granulation or hydrogen reduction at higher temperatures.
3. Core Industrial Applications
• Hard Alloys: Mixed with carbon black to form tungsten carbide (WC), used in cutting tools, mining bits, and wear-resistant components.
• Electrical & Electronics: Manufactures filaments for incandescent lamps, electron emitters, and high-current electrical contacts due to its excellent electrical conductivity and arc resistance.
• Aerospace & Defense: Sintered into high-density parts for counterweights, radiation shielding, and rocket engine components.
• Chemical Catalysts: Supports in hydrogenation reactions for petroleum refining and organic synthesis.
4. Quality Grades & Standards
• Fine Powder (WF-10/WF-15): Particle size < 3 μm, used for ultrafine WC powders.
• Medium Powder (WM-20/WM-40): Particle size 3–10 μm, standard grade for general hard alloys.
• Coarse Powder (WC-60/WC-100): Particle size > 10 μm, applied to large structural parts.
Packaging: Vacuum-sealed steel drums (25kg/50kg) to prevent oxidation and moisture absorption.
5. Storage & Handling
Store in a dry, ventilated environment away from oxidizing agents. Avoid prolonged exposure to air to prevent surface oxidation, which can impact sintering performance. The shelf life in vacuum packaging exceeds 24 months.
