High purity zirconia ceramic beads

---

High purity zirconia ceramic beads are precision industrial grinding media made from ultrafine zirconia powder as the core raw material, through isostatic pressing and high-temperature sintering processes. With its extremely high density, hardness, and excellent wear resistance, it has become a key consumable for achieving ultra-fine grinding and dispersion of materials in industries such as new energy, electronic ceramics, and high-end coatings, and is the core guarantee for improving product yield.

Directly addressing core requirements and solving key challenges
In the pursuit of ultimate quality in modern industrial production, is your production line facing the following challenges: traditional grinding media wear out quickly, causing materials to be frequently contaminated by metal impurities? Low grinding efficiency makes it difficult to meet the requirements of nanoscale particle size distribution? Or is the equipment severely damaged and the overall production cost remains high? Our high-purity zirconia ceramic beads are designed to solve these production bottlenecks. They can effectively reduce material pollution, greatly improve grinding efficiency, and significantly extend equipment service life, helping you easily overcome process difficulties.

Analysis of Core Advantages and Application Value

1. Excellent material science properties
   Ultra high density and hardness: Our zirconia beads have a true density of over 6.0g/cm ³ (far exceeding the 2.6g/cm ³ of ordinary alumina ceramics), and a Vickers hardness of over 1200HV. This means that under the same conditions, it can provide greater impact energy, has extremely high grinding efficiency, and has extremely low self wear.
   Excellent toughness and strength: Adopting the tetragonal zirconia (TZP) toughening mechanism, the bending strength is ≥ 1000Mpa, and the fracture toughness is excellent. It is not easy to crack or peel off in high-speed and high concentration sand mills, greatly reducing the risk of bead breakage.
   Chemical inertness and zero pollution: It has excellent acid and alkali corrosion resistance, and extremely stable chemical properties. During the grinding process, almost no impurities are introduced, ensuring the purity of the final product, which is particularly suitable for the electronic paste and pharmaceutical fields with strict purity requirements.
2. Wide range of core application scenarios
   New energy battery materials: Perfectly adapted to the nanoscale grinding of lithium battery positive and negative electrode materials (such as lithium iron phosphate and ternary precursors), effectively controlling particle size distribution, improving battery rate performance and cycling stability.
   Electronic Ceramics and Semiconductors: Meet the extreme requirements of MLCC (Multi Layer Ceramic Capacitor), 5G filters, electronic pastes, etc. for ultrafine dispersion and zero pollution.
   High end coating ink: Used for dispersing pigments in automotive paint, industrial coatings, and inkjet printing ink, making the color more vivid and the texture more delicate.
   Biopharmaceuticals and Cosmetics: With excellent biocompatibility, it is widely used in dental implant polishing, artificial joint treatment, and grinding of active ingredients in high-end cosmetics.
3. Comprehensive specification customization services
   We are well aware of the differentiated requirements of different equipment and processes for grinding media, and therefore provide highly flexible customized services:
   Particle size customization: covering a full range of specifications from submicron to millimeter level. Regular stock includes sizes such as φ 0.1mm, 0.3mm, 0.5-0.8mm, 1.0-1.2mm, 2.0-2.5mm, etc. Special sizes can also be customized as needed.
   Formula optimization: The optimal stabilizer type (such as yttrium stabilized or cerium stabilized) can be matched based on the acidity and alkalinity of the customer’s materials and the model of the grinding equipment to ensure optimal process compatibility.

Application case sharing
Lithium iron phosphate grinding project of a certain lithium battery enterprise
The customer is facing severe process challenges in producing high-end power battery cathode materials: the original grinding medium has a high wear rate in high solid content slurries, which not only leads to excessive magnetic foreign objects in the product, but also generates high temperatures due to intense friction, accelerating the oxidation of iron ions and seriously affecting batch consistency.
After introducing our customized high-density zirconia ceramic beads, the slurry temperature rise was reduced by about 42% at the same speed due to its excellent thermal conductivity and low friction coefficient, effectively suppressing impurity leaching. Meanwhile, its extremely high sphericity (≥ 0.98) and precise dimensional tolerances ensure the uniformity of the grinding force field. After 200 hours of continuous production verification, the D90/D10 particle size span of the customer’s production line has been stably controlled within 1.42, far exceeding industry standards. The single ton grinding cost has decreased by 11.6%, successfully solving the long-standing quality fluctuation problem that has plagued the production line.
