High density zirconia ceramic beads

---

High density zirconia ceramic beads are a top-level industrial grinding medium made from high-purity zirconia as the matrix through precision sintering technology. With its extremely high density, excellent wear resistance, and chemical stability, it has become the core consumable for achieving ultrafine grinding and nanoscale dispersion of materials in modern high-end manufacturing. It can significantly improve grinding efficiency and ensure the ultimate purity of materials.

Key issues solved for you
In actual production, we are well aware that you may face challenges such as low grinding efficiency, cross contamination of materials, severe equipment wear, and frequent replacement of consumables. High density zirconia ceramic beads are designed to address these issues:
Improve grinding efficiency: The extremely high specific gravity (≥ 6.0 g/cm ³) brings powerful kinetic energy, significantly shortening the grinding cycle.
Eliminate material contamination: High purity and extremely low self abrasion ensure that the purity of highly sensitive materials such as lithium battery materials, pharmaceuticals, and food is not affected.
Reduce overall costs: Its super toughness makes it less prone to breakage during high-speed grinding, and its long lifespan effectively reduces your consumables and downtime replacement costs.

Advantages and Application Value
High density zirconia ceramic beads use tetragonal zirconia (t-ZrO ₂) as the matrix and are stabilized by yttrium oxide (Y ₂ O3). This special crystal structure endows microbeads with a unique “phase transition toughening” mechanism, which can absorb a large amount of fracture energy when subjected to external impact, significantly improving crack resistance.

Core advantages:
Ultra high specific gravity and hardness: The true density is stable at 6.0 g/cm ³ or above, and the Vickers hardness is ≥ 1300 HV. Compared with traditional zirconium silicate beads (with a specific gravity of about 4.0 g/cm ³) and alumina beads, its impact force is stronger, and the grinding efficiency can be improved by 30% -50%.
Ultimate wear resistance and low abrasion: In the rigorous water self abrasion test, the water remains clear for a long time. Its wear resistance is about 50 times that of glass beads and 5 times that of zirconium silicate beads, with extremely low self abrasion, greatly reducing material pollution.
Excellent chemical stability: ZrO ₂ purity ≥ 95.2%, with strong acid and alkali corrosion resistance, can work stably in extreme environments with pH values of 1-14, and has no risk of leaching.
Precise sphericity and surface finish: advanced spray granulation and isostatic pressing technology are adopted, with roundness ≥ 95% and surface roughness (Ra) controlled below 0.02 μ m. A perfect spherical shape not only has good fluidity, but also reduces wear on the inner wall of the grinding equipment.

Wide range of application areas:
New energy battery materials: nanoscale dispersion and grinding of lithium battery positive and negative electrode materials, and membrane coating materials.
Electronics and Precision Ceramics: MLCC (Multi Layer Ceramic Capacitor), Electronic Slurry, Semiconductor Polishing Slurry, Ceramic Ink.
Biopharmaceuticals and Food: Non polluting ultrafine grinding of drug suspensions, health supplements, food additives, and high-end cosmetics.
High end coatings and inks: Fine grinding of inkjet printing ink, special paints, and high-end pigments.

Ultra fine and special customization: capable of stable mass production of ultra-fine zirconia microspheres ranging from 0.03mm to 0.05mm, meeting the extreme grinding needs of high-end sand mills; Simultaneously supporting customization of large sizes (such as over 10mm) and special formulas.

Customer application case sharing
Case 1: A leading lithium battery material company
The customer is extremely sensitive to metal foreign matter contamination and requires extremely narrow particle size distribution when producing high-end silicon carbon negative electrode materials. Previously, grinding beads were used, although their performance was still acceptable, the cost was extremely high and the supply cycle was long. After introducing our high-density zirconia microbeads (with a specification of Φ 0.1mm), after 6 months of continuous production line testing, the data showed that the magnetic foreign matter content in the material was much lower than the industry standard, the grinding efficiency was improved by about 15%, and the wear performance was almost the same as previous products.
Case 2: A well-known electronic ceramic ink manufacturer
When customers grind electronic ceramic ink, nozzle blockage often occurs due to broken or worn grinding beads, which seriously affects the yield of inkjet printing. We recommended customized high toughness zirconia beads for it and optimized the speed and filling rate parameters of its sand mill. After three months of use, customers reported a decrease of over 90% in nozzle clogging rate, a significant improvement in the stability of ink particle fineness, and a significant increase in product yield.
