Overview
GaoKeXin Vanadium Target is a specialized form of high-purity vanadium used in physical vapor deposition (PVD) processes, particularly sputtering. These targets are manufactured through powder metallurgy or vacuum melting techniques to achieve the required density and microstructure. Vanadium targets are valued for their ability to deposit thin films with specific electrical and optical properties. The 'GaoKeXin' designation typically indicates a Chinese-manufactured product meeting industrial standards for purity and performance in coating applications.
Physical and Chemical Properties
Vanadium targets exhibit a body-centered cubic crystal structure and maintain stability under high-temperature vacuum conditions. The material shows good thermal conductivity (30.7 W/m·K) and electrical resistivity (about 25.0 μΩ·cm). Key quality parameters include purity (typically 99.9%-99.99%), grain size uniformity, and low impurity levels (especially oxygen <500ppm). The targets demonstrate excellent bonding characteristics when used with copper or aluminum backing plates in sputtering systems.
Main Applications
Primary use is in semiconductor manufacturing for creating barrier layers and contact films in integrated circuits. Vanadium films serve as diffusion barriers between silicon and aluminum in microelectronics. Other applications include optical coatings for specialized lenses, decorative coatings in architectural glass, and functional coatings in energy storage devices. Research institutions utilize vanadium targets for developing smart window technologies and thin-film batteries.
Safety and Storage
Vanadium metal targets are generally stable but may produce combustible dust during machining. Always use local exhaust ventilation when cutting or grinding targets. Store in original packaging under dry, inert conditions to prevent surface oxidation. Moisture-resistant packaging is recommended for long-term storage. Unused target materials should be kept in vacuum-sealed containers when not in immediate use.
B2B Procurement Guide
When sourcing vanadium targets, clearly specify: 1) Purity grade (3N, 4N, etc.), 2) Physical dimensions and tolerance, 3) Bonding requirements (if applicable), 4) Surface finish specifications. Request material test reports including impurity analysis. For high-volume purchases, consider negotiating pricing based on annual consumption. Lead times typically range 4-8 weeks for standard sizes. Quality certifications like ISO 9001 are recommended for critical applications.
