The Technical Edge of Yttria Stabilized Zirconia (Y-TZP)

Yttria Stabilized Zirconia Beads (ZR95) are favored in high-energy grinding applications due to their optimized material properties. The working principle depends on the high density of the beads, which transfers stronger kinetic energy and crushing force to the material being processed.

1. Nano Zirconia Beads (ZR95)

These beads are high-quality yttria-stabilized zirconia beads produced through a unique extrusion molding process using ultrafine grain, high-purity, and fine raw materials.
  • Extreme Hardness:? They possess a Vickers Hardness of ≥ 1300 HV.
  • Ultra-Fine Surface:? The beads have an extremely smooth and fine surface, with a surface finish (Sa) of 20-30 nm.
  • Specific Applications:? Suitable for the grinding and dispersion of nanoparticle materials. They are the optimal choice for ultra-fine dispersion under high viscosity conditions.

2. High-Purity Zirconia Beads (ZR95)

These media are refined from high-purity Y-TZP? raw materials.
  • High Wear Resistance:? They demonstrate good wear resistance and strength, with a Vickers Hardness of ≥ 1250 HV.
  • Equipment Protection:? They provide self-lubrication and sphericity, resulting in less wear to the grinding equipment.
  • Application Scope:? Suitable for dispersion across paint and coatings, textile dyes, pharmaceutical chemicals, cosmetics, and battery materials.

Critical Applications: Where Purity and Efficiency Meet

CRAC Zirconia Beads (ZR95) are indispensable in industries where quality consistency and minimal contamination are non-negotiable.
  1. New Energy and Lithium Battery Materials:
    CRAC beads are used for the grinding and superfine dispersion of new energy high-end materials, specifically lithium iron phosphate cathode materials? and silicon carbon anode materials. This application helps to minimize pollution to battery materials, which is crucial for maximizing performance.
  2. Pharmaceutical and Biochemical Grinding:
    In the pharmaceutical and biochemical fields, ceramic media are utilized in stirring ball mills to ensure the preparation of active ingredients without polluting the ground products. CRAC high-performance nano ceramic microbeads have the lowest wear during the grinding process and can be sterilized by high-pressure sterilization without changing their extremely high mechanical stability.
  3. Coatings, Inks, and Pigments:
    When used to grind dye particles or pigments, ceramic microspheres crush the particles to the micrometer and partially to the nanometer range in suspension or dispersion. Zirconia beads are also used for the ultrafine dispersion of electronic materials, magnetic materials, carbon nanotubes, and graphite.

Quality Control: Ensuring Consistent Precision in Grinding Media

To achieve the "zero-defect" goal and ensure that zirconia beads consistently meet stringent specifications, CRAC employs a closed-loop quality assurance system across three phases.

1. Raw Material Quality Control

Inspection procedures start with testing incoming materials, including Chemical Composition (XRF), Crystalline Phase (XRD), Particle Size Distribution (PSD), Specific Surface Area (BET), and Vickers Hardness (HV).

2. Production Process Management

The Nano zirconia beads are manufactured using a unique extrusion molding process? to ensure the green body is uniform and compact. The process management system maintains consistency through:
  • Sintering Process:? Checks include temperature control and compressive strength.
  • Selection and Screening:? Adopting a three-level selection and two-level screening process ensures the sphericity and particle size concentration of the zirconia beads.
  • Polishing Process:? Checks surface finish and apparent density.

3. Shipment Inspection Management

Final checks before the product leaves the warehouse verify key parameters, including:
  • Particle Size Distribution, Internal Structure, Density, Compressive Strength, Surface Finish, and Vickers Hardness (HV).
  • Specific products may be tested using UT non-destructive testing.
