High-performance ceramic materials
Zirconia beads, as a high-performance ceramic material, play a vital role in industrial applications due to their high density, exceptional hardness, superior wear resistance, chemical stability, and toughness. Based on their zirconium content and physical properties, they are primarily classified into two categories: 65-zirconia beads (zirconium silicate beads) and 95-zirconia beads (high-purity zirconia beads), each suitable for different workpieces and manufacturing processes.
Workpieces used in the fields of grinding and dispersion
In industrial processes requiring ultra-fine grinding and uniform dispersion of materials, zirconia beads serve as the essential grinding medium.
• High-precision grinding (using 95% zirconia beads): Suitable for industries requiring extremely high purity, fineness, and efficiency.
◦ Electronic materials: used for grinding positive and negative electrode materials of lithium batteries (e.g., ternary materials, lithium iron phosphate) and electronic slurries (e.g., silver slurry, copper slurry), ensuring uniform particle size and optimizing the consistency of electrochemical performance.
◦ Pharmaceuticals and Food: In the production of pharmaceuticals, foods, and cosmetics requiring "zero contamination," 95Zr beads with extremely low wear exhibit inert zirconium oxide as wear products. Moreover, by strictly controlling the leaching levels of heavy metals such as lead and arsenic, these standards comply with FDA or relevant pharmacopoeial requirements, ensuring product safety.
◦ High-end ceramics: An ultrafine powder slurry used for preparing electronic ceramics and structural ceramics, designed to achieve optimal particle size distribution, fine particle size characteristics, low wear resistance to prevent the introduction of new impurities, and ensure the strength and density of the sintered material.
◦ Special coatings and inks: Used as pigments for grinding automotive paints, UV inks, digital inkjet inks, etc., to achieve fine particle size and enhance color uniformity and adhesion.
• Standard industrial grinding (using 65 zirconia beads): Suitable for grinding materials with medium to low viscosity, offering excellent cost-effectiveness.
◦ Coatings and paints: Used for grinding pigments and fillers to enhance the gloss and stability of coatings.
◦ Pesticides: Used for crushing and dispersing active ingredients in the production of pesticide suspensions.
◦ Papermaking: Used for grinding heavy fillers such as calcium carbonate.
Workpieces in the field of surface treatment
Leveraging the high toughness and spherical surface of zirconia beads (65Zr), this method enables efficient sandblasting cleaning or precision polishing of workpieces.
• Precision polishing: Suitable for workpieces requiring a mirror finish or removal of fine burrs
- Automotive wheel hubs: Through vibration polishing or centrifugal polishing machines, zirconia beads interact with the hub surface through friction, achieving a smooth or even mirror-like finish.
- Metal and ceramic structural components: Designed for polishing workpieces made of stainless steel, titanium alloys, ceramics, and other materials to remove machining scratches and burrs while enhancing surface finish.
- Jewelry: Suitable for polishing precious metals such as gold, replacing partial manual labor and enhancing efficiency.
• Sandblasting cleaning: Suitable for workpieces requiring removal of surface oxide layers, rust, or old coatings.Zirconia beads' high hardness effectively cleans surfaces while causing less damage to the substrate compared to media such as steel shot.
Workpieces in the field of functional components
High-precision zirconia beads can serve as critical components due to their exceptional resistance to high temperatures, wear, and corrosion.
• Bears and balls: Used as bearing balls or rollers, particularly suitable for equipment requiring corrosion resistance, insulation, or operation in high-temperature environments, such as precision bearings in chemical pumps and aerospace machinery.
• Valves and Seals: The valve core used in ball valves utilizes its high hardness and wear resistance to ensure long-term sealing performance.
• Dental materials: In dental restoration, they serve as high-temperature bearing beads, providing uniform support to prevent creep deformation of all-ceramic crowns during high-temperature sintering.
In summary, zirconia beads have a wide range of applications. The selection of the appropriate type of zirconia bead depends on the material of the workpiece, processing requirements, and performance specifications of the final product. Their outstanding physical and chemical properties make them an indispensable key material in modern industry.
