Zr target

When purchasing Zirconium (Zr) targets, the most critical factor is Purity, typically requiring 99.2% to 99.95% depending on the application. You must also specify the Relative Density, which should ideally be >99% to ensure stable sputtering rates and minimize particle generation. Additionally, pay attention to Grain Size; a fine and uniform grain structure (typically <100μm) is essential for consistent film thickness and quality.

Zr targets are widely used in PVD (Physical Vapor Deposition) coating processes. Key scenarios include Decorative Coatings (providing a gold-like finish for hardware and jewelry), Hard Coatings (for cutting tools to improve wear resistance), and Optical Coatings. They are also vital in the Semiconductor and Solar Cell industries for creating diffusion barriers and anti-reflective layers.

Suppliers should provide a Certificate of Analysis (COA) for every batch, detailing impurity levels (especially Hafnium content, as Zr and Hf are naturally co-existent). Ensure the manufacturer follows ISO 9001 for quality management. For high-end electronics, compliance with RoHS and REACH standards is mandatory to ensure the absence of hazardous substances.

You must specify the shape: Planar (Circular or Rectangular) or Rotary (Cylindrical). For large-scale industrial use, Rotary Targets offer higher material utilization. If the target is fragile or has low thermal conductivity, request Indium Bonding to a copper backplate to prevent cracking and improve heat dissipation during high-power sputtering.

Always request a Pre-shipment Inspection (PSI) and a third-party lab test report (such as GDMS or ICP-OES analysis). On Made-in-China.com, prioritize Audited Suppliers who have had their manufacturing facilities and quality control processes verified by independent bodies like SGS or TÜV Rheinland.

Zr targets are heavy and can be brittle. Ensure the supplier uses Vacuum Sealed Packaging to prevent oxidation and Wooden Crate Reinforcement with shock-absorbing foam. Since Zirconium fines can be flammable, ensure the bulk solid targets are clearly labeled to comply with International Maritime Dangerous Goods (IMDG) codes if applicable, though solid targets are generally stable.

Zirconium prices are influenced by raw material ore costs. It is wise to negotiate a Formula-Based Pricing model for long-term contracts or lock in prices during market lows. For bulk orders, aim for a 10-15% discount compared to sample pricing, and always clarify if the quote includes the Copper Backplate and Bonding Fees.

Use secure payment methods such as Letters of Credit (L/C) for large volumes or Escrow-based trade terms offered through reputable platforms. Ensure all technical drawings and tolerance requirements (e.g., +/- 0.1mm) are attached to the Proforma Invoice (PI) to serve as legal recourse in case of dimensional deviations.
