Zinc tungstate sputtering targets are functional ceramic targets prepared from high-purity ZnWO₄ powder through advanced ceramic processing techniques. It integrates the outstanding scintillation properties, photocatalytic activity, and excellent chemical stability of zinc tungstate materials, serving as the core source material for depositing high-quality ZnWO₄ thin films in physical vapor deposition processes. Such films find significant applications in novel radiation detection, environmental purification photocatalysts, and specialty functional coatings.

Q1: What are the primary applications of ZnWO4 targets?
A1: Primarily used for depositing radiation detection scintillation films and environmental purification photocatalytic films—its two core application areas.
Q2: What purity requirements apply to the target material?
A2: To ensure film performance, purity is typically required to be no less than 99.9%. For high-performance applications, 99.99% (4N) or higher purity is recommended.
Q3: What precautions should be taken during use and maintenance?
A3: The target material is brittle and requires careful handling during removal and placement. Store in a sealed, moisture-proof container within a clean, dry environment. Keep the target surface clean after use.
Q4: Why is bonding service necessary?
A4: Bonding to a metal backing plate ensures efficient heat dissipation and secure mounting. This prevents thermal stress cracking of ceramic targets during sputtering, safeguarding process stability.
