High hardness zirconia ceramic beads

---

High hardness zirconia ceramic beads are an advanced ceramic grinding medium made from sub nanometer level high-purity raw materials and sintered at high temperature of 1600 ℃. With its extremely high Vickers hardness, outstanding wear resistance, and excellent thermal stability, it has become the core material for modern industry to achieve “zero pollution” ultrafine grinding and precision polishing, and can still maintain perfect sphericity and physical properties under extreme working conditions.

Direct Challenge: What core challenges can it solve for your production?
From the perspective of production and research and development, do you often face the following difficulties in material handling?
Low grinding efficiency: Ordinary grinding media have low specific gravity and insufficient kinetic energy, resulting in material particle size that cannot meet nanoscale requirements, and the production cycle is infinitely extended.
Serious cross contamination: During the grinding process, the medium wears off and impurities mix into the slurry, resulting in the direct scrapping of high-purity products such as electronic materials, pharmaceuticals, and food.
High equipment loss and cost: The medium is prone to breakage and wear, which not only increases procurement costs due to frequent replacement, but also blocks the equipment screen due to broken fragments, increasing downtime for maintenance.
High hardness zirconia ceramic beads are designed to solve these core problems. It can shorten grinding time with extremely high crushing efficiency, eliminate material pollution with chemical inertness, and significantly reduce your overall production cost with extremely low self abrasion.

Our zirconia ceramic beads have reached the top level in both physical and chemical properties in the industry, providing users with valuable grinding solutions:
Excellent product advantages
Ultra high hardness and wear resistance: The Mohs hardness can reach level 9 (Vickers hardness ≥ 11.0GPa), and the wear resistance is 30-50 times that of ordinary glass beads and about 5 times that of zirconium silicate beads. This means that under the same grinding conditions, our beads hardly wear out, greatly extending their service life.
High density brings high kinetic energy: true density>6.0g/cm ³, much higher than alumina beads and ordinary zirconium beads. During high-speed operation of the sand mill, the impact force of a single bead is stronger, which can increase the grinding efficiency by 30% -50% and easily handle the dispersion and grinding of high viscosity and high hardness materials.
Ultimate chemical stability: It has strong acid and alkali resistance, corrosion resistance, and almost no strength degradation at high temperatures. Its non-magnetic and biocompatible characteristics ensure true “zero pollution” when grinding electronic pastes and pharmaceutical preparations.
Perfect sphericity and surface smoothness: Adopting isostatic pressing and precision screening technology, the roundness is ≥ 95%, and the surface is as smooth as pearls. This not only reduces energy loss during the grinding process, but also avoids scratching the surface of the workpiece, making it particularly suitable for mirror polishing.

Comprehensive specification customization service
We are well aware that different equipment and processes have differentiated requirements for grinding media, so we provide flexible customized services:
Particle size customization: We offer a full range of specifications from 0.1mm (nanoscale grinding) to 10mm (heavy-duty impact grinding). Small particle size (such as 0.3mm-0.8mm) is suitable for nanomaterials that pursue ultimate fineness; Large particle sizes (such as 3mm-6mm) are suitable for rough grinding and high viscosity materials.
Formula customization: Depending on the application scenario, different zirconia content formula options such as 95 type (yttrium stable, balancing toughness and cost) and 99 type (ultra-high purity, suitable for semiconductors and high-end pharmaceuticals) can be provided.

Why choose us? Real customer application cases
We not only provide products, but also offer complete solutions based on fluid mechanics and grinding processes. Here are real cases where we assist clients in solving practical problems:
Case 1: A battery company – Breaking through the bottleneck of energy density
Facing a problem: A well-known lithium battery manufacturer is limited by traditional grinding media when producing new lithium iron phosphate cathode materials, and the slurry particle size cannot be stably controlled below 500nm, seriously affecting the battery’s cycle life and charging and discharging efficiency.
Solution: We recommend 0.4mm high-purity yttrium stabilized zirconia microspheres for it. By utilizing its high density and hardness characteristics, efficient nanoscale dispersion has been achieved in a horizontal sand mill.
Application effectiveness: After actual testing on the production line, the average particle size of the material has been successfully reduced to below 300nm, and the batch stability is excellent. Not only has the energy density of the battery been significantly improved, but due to the extremely low wear of the medium, the content of magnetic foreign objects in the slurry has also been greatly reduced, perfectly meeting the production standards of automotive grade batteries.
Case 2: High end electronic ceramic manufacturer – achieving mirror polishing with zero scratches
Problem faced: A customer producing precision ceramic substrates always leaves small scratches on the surface of the product during the final polishing process using traditional abrasives, resulting in a yield rate hovering around 85% for a long time.
Solution: We have customized specialized polished zirconia beads with extremely high surface finish and narrow particle size distribution, and optimized the rotational speed parameters.
Application effect: The perfect spherical structure of the bead was uniformly micro cut on the surface of the workpiece in the vibration polishing machine. The surface roughness of the final product has been significantly reduced, achieving the desired mirror effect without any scratches.
Case 3: Special Ink and Coating Enterprises – Eliminating Cross contamination of Color Pastes
Problem faced: In the production of digital printing ink with frequent color changes, ordinary media are prone to absorbing pigments and wear and tear, leading to time-consuming and labor-intensive cleaning equipment, and easily causing color differences between batches.
Solution: Introduce zirconia ceramic beads with strong chemical inertness as the grinding medium.
Application effect: Due to the dense and smooth surface of zirconia beads, which do not adsorb pigments and are easy to clean, the color change cleaning time has been shortened by 60%. At the same time, its extremely low wear completely eliminates the influence of impurities in the medium on the purity of the ink, ensuring the vividness and stability of the ink color.
