Zirconia ceramic price

The price of zirconia ceramic is primarily driven by its chemical composition (Yttria content) and manufacturing process. For industrial applications, look for Yttria-Stabilized Zirconia (YSZ), typically 3mol% (3Y-TZP), which offers the best balance of fracture toughness and wear resistance. Key metrics include a density of ≥6.0 g/cm³, Vickers hardness of >1200 HV, and flexural strength exceeding 900 MPa. For dental grade, translucency levels (High vs. Super Translucent) significantly impact the cost.

Selection depends on the environment: Structural components (valves, pump parts) require high mechanical strength and corrosion resistance. Electronic substrates demand high dielectric constants and thermal stability. Dental blocks require biocompatibility (ISO 13485) and aesthetic translucency. Always match the grain size (typically <0.5μm) to the application, as finer grains generally offer better aging resistance (hydrothermal stability).

Ensure the supplier adheres to ISO 9001 for general manufacturing. For medical or dental zirconia, CE marking, FDA registration, and ISO 13485 are mandatory. For industrial wear parts, request ASTM C1161 (flexural strength) and ASTM C1327 (Vickers hardness) test reports. If sourcing from Made-in-China.com, prioritize Audited Suppliers who provide third-party verification of their production capacity and quality control systems.

To optimize costs, evaluate the Total Cost of Ownership (TCO) rather than just the unit price. High-quality zirconia reduces downtime and replacement frequency. Negotiate tiered pricing; for example, moving from 100 units to 1,000 units can often yield a 15-25% discount. Additionally, consider near-net-shape forming (like injection molding or dry pressing) to reduce expensive diamond grinding and post-processing labor costs.

The primary risk is material substitution, where lower-grade alumina-toughened zirconia (ATZ) is sold as pure YSZ. Another risk is micro-cracking caused by improper cooling cycles during sintering, which is invisible to the naked eye. To mitigate this, use Trade Assurance on Made-in-China.com and mandate a Pre-Shipment Inspection (PSI) to verify physical properties via lab testing.

Be specific about dimensional tolerances (e.g., ±0.01mm) and surface roughness (Ra). Zirconia is difficult to machine after sintering; therefore, clarify who bears the cost of diamond tooling. Ask for a detailed QC report for every batch. Professional suppliers on Made-in-China.com should be able to provide SEM (Scanning Electron Microscopy) images to prove grain uniformity upon request.

Zirconia is brittle despite its hardness. Ensure the contract specifies vacuum packaging or shock-absorbent foam (EPE) and double-walled corrugated boxes. For international shipping, use pallets with corner protectors to prevent impact. Confirm the HS Code (typically 6909.11 or 6909.12) to accurately calculate import duties and ensure compliance with your local customs regulations.

Always verify the supplier's business license and export qualifications. Utilize the secured payment systems provided by Made-in-China.com to ensure funds are only released upon proof of shipment. For large-scale contracts, consider a factory audit to confirm the supplier owns the sintering furnaces and CNC grinding equipment rather than outsourcing to a third party.
