Customized Zirconia Ball Milling Jars And High Temperature Resistant Zirconia

This portfolio represents a specialized manufacturing and supply service focused on advanced zirconia ceramics. The core offerings are customized zirconia ball milling jars and high-temperature resistant zirconia structural parts, all available at competitive, discounted prices. The foundation of these products is precision ceramic processing, which ensures superior performance, reliability, and longevity.

These are grinding containers used in ball mills, designed for size reduction, dispersing, and mixing of materials. Customization is a key feature, allowing them to be tailored to specific application needs far beyond standard offerings.

• Material: Made from Yttria-Stabilized Zirconia (YSZ), typically with 3mol% or 5mol% Yttria. This provides exceptional wear resistance and prevents contamination of the milled material.
• High Wear Resistance: Zirconia's incredible hardness (Vickers hardness > 1200) ensures the jar lasts significantly longer than other materials like alumina, stainless steel, or PTFE, reducing downtime and replacement costs.
• Contamination-Free Milling: Zirconia is chemically inert and non-magnetic. It will not react with or introduce impurities into the sample, which is critical for R&D, pharmaceuticals, and electronics material production.
• High Density & Strength: The fine-grained, high-density structure minimizes porosity, leading to a smoother inner surface that is easier to clean and less likely to trap particles.

• Size & Volume: From small 50ml jars for lab research to large 10L+ jars for production.
• Geometry: Standard cylindrical, tapered, or unique shapes as required.
• Lid Design: Custom ports for inert gas, vacuum, or temperature monitoring. Various sealing mechanisms (e.g., O-ring, clamp-on).
• Internal/External Finishing: Polished to a mirror finish for easy cleaning or a specific roughness.

• Pharmaceutical R&D and production.
• Battery material synthesis (e.g., cathode & anode powders).
• Electronics ceramics (dielectrics, ferrites).
• Pigment and dye dispersion.
• Geology and mineral sample preparation.

These are engineered components designed to perform in demanding mechanical and thermal environments where metals or plastics fail. They are not just materials, but fully finished, ready-to-install precision parts.

• Exceptional High-Temperature Resistance: Zirconia parts can operate continuously at temperatures up to 1,400°C - 1,600°C (depending on the stabilizer), maintaining their structural integrity.
• Remarkable Fracture Toughness: Zirconia has the highest toughness of all advanced ceramics due to a mechanism called "transformation toughening," making it highly resistant to chipping, cracking, and thermal shock.
• Excellent Mechanical Properties:
• High Strength: Bending strength can exceed 1,000 MPa.
• Low Thermal Conductivity: Acts as an excellent thermal insulator.
• Wear & Corrosion Resistance: Impervious to most acids, alkalis, and molten metals.

• Insulation Components: Thermocouple sleeves, furnace liners, heating element holders.
• Wear Parts: Nozzles for sandblasting or spray drying, guides, rollers, bearings, and cutting tools.
• Fixturing & Setter Plates: Used in sintering furnaces for electronics (e.g., MLCCs) due to their chemical inertness and stability.

• Aerospace (thermal barrier coatings, engine components).
• Semiconductor manufacturing (wafer processing fixtures).
• Heat treatment and metallurgical industries.
• Automotive (sensors, wear-resistant inserts).
• Medical and dental implants and instruments.

This is the technological backbone that enables the production of high-quality zirconia parts. It involves a multi-step, tightly controlled manufacturing process.

• Powder Preparation & Formulation:
  • Using high-purity, sub-micron zirconia powder with precise yttria stabilizer ratios.
  • Custom additives (sintering aids, pigments) can be incorporated.
• Forming / Shaping:
  • Uniaxial / Isostatic Pressing: For simple, solid shapes like blocks, rods, and simple plates. High volume production.
  • Injection Molding: For complex, near-net-shape parts with high dimensional repeatability. Ideal for mass production.
  • Tape Casting: For producing thin, flat sheets used in electronics.
  • Extrusion: For creating long products with a consistent cross-section (e.g., tubes, rods).
• Machining in the "Green" or "Bisque" State:
  • After forming, the part is in a soft, chalk-like state ("green") or a partially sintered, porous state ("bisque").
  • CNC machining is performed at this stage to achieve intricate geometries, tight tolerances, and specific surface finishes that are impossible to achieve with pressing/molding alone. This is a key aspect of "customization."
• Sintering:
  • The core process where the shaped part is fired in a high-temperature kiln (typically >1,500°C).
  • The particles fuse together, causing the part to shrink significantly (20-25%) and densify into a solid, polycrystalline ceramic with its final mechanical properties.
• Precision Finishing & Hard Machining:
  • After sintering, the part is extremely hard. Any further machining requires diamond-impregnated tools.
  • Processes like diamond grinding, lapping, and polishing are used to achieve ultra-precise final dimensions (tolerances within ±0.001"), specific surface roughness (Ra < 0.1 µm), and sharp edges.
