Zirconium Particles
Zirconium particles are a granular material made of zirconium (chemical symbol Zr). Zirconium is a silver white metal with high melting point, low density, good corrosion resistance, and excellent chemical stability, especially outstanding in high temperature and corrosive environments. Zirconium particles are widely used in multiple fields due to their unique physical and chemical properties.

Production process
Raw material purification
Preparation of sponge zirconium:
Chlorination method: Zirconia is chlorinated to produce zirconium tetrachloride (ZrCl ₄), which is then reduced by magnesium (Kroll method) or calcium to produce sponge zirconium.
Hydrogen reduction method: Zirconia reacts with hydrogen gas at a high temperature of 800 ℃ to generate porous sponge zirconium blocks.
High purification treatment:
Purification using vacuum electron beam melting or iodination method, with hafnium content<0.01% and oxygen impurities<500ppm.
Particle molding
Crushing and screening: Sponge zirconium blocks are mechanically crushed and then subjected to vibration screening to obtain target particle size (usually 0.5-5mm).
Ball milling shaping: Zirconia particles are formed by titration molding process, with colloidal slurry dripping and cooling liquid shaping, and then sintered to a sphericity greater than 99%.
Surface passivation: Acid washing (nitric acid+hydrofluoric acid mixture) forms a dense oxide film, enhancing corrosion resistance.
Application Fields
1. New energy and nuclear energy
Solid state battery: High purity zirconium particles are used to deposit lithium lanthanum zirconium oxide (LLZO) electrolyte layer to enhance ion conductivity.
Nuclear fuel cladding: Zircaloy-4 alloy tubes made by sintering nuclear grade zirconium particles, responsible for 90% of nuclear reactor structural components.
2. High end manufacturing
Aerospace: As a raw material for thermal barrier coatings (YSZ) on turbine blades, it can withstand temperatures up to 1200 ℃.
Wear resistant components: Zirconia ceramic beads are used for ultrafine grinding (particle size ≤ 1 μ m), with a lifespan 5 times that of steel beads.
3. Chemical and Medical
Corrosion resistant reactor: Zirconium particles are pressed and sintered into valves and pump bodies, which are resistant to hydrochloric acid media.
Biological implants: Zirconium niobium alloy particles 3D printed artificial joints with a service life of over 20 years.
Zirconium particles, as a key material in modern industry and technology, demonstrate outstanding achievements in materials science with their unique properties and wide applications.
From nuclear energy to healthcare, from new energy to aerospace, zirconium particles are driving technological innovation in multiple fields. With the continuous optimization of preparation processes, its application prospects will become even broader.
