Graphite-Silver

Graphite-Silver Sputtering Target is a composite target material used in physical vapor deposition (PVD) processes to deposit thin films that combine the unique properties of graphite (carbon) and silver. This target is created by blending high-purity graphite with silver particles, achieving a material that offers both electrical conductivity and lubricity. These targets are especially useful in applications that require low friction, good wear resistance, and high conductivity.

Physical Properties:

Chemical Formula: C-Ag.

Appearance: Gray to dark gray, with a slightly metallic sheen due to the presence of silver.

Density: Varies based on the silver content but generally higher than pure graphite targets.

Structure: Typically a composite or alloyed structure, where silver is evenly distributed within the graphite matrix for uniform sputtering.

Applications of Graphite-Silver Sputtering Targets:

Electronics and Semiconductor Industry: Used to create conductive coatings that also need to be resistant to wear, especially in high-temperature or friction-prone environments.

Tribological Coatings: Useful for creating coatings on moving parts, such as bearings and sliding contacts, due to the lubricity provided by graphite.

Optical Coatings: In some optical devices, graphite-silver films can reduce glare while providing conductive properties.

Aerospace and Automotive Components: Coatings for components that need to withstand friction and wear, as well as extreme temperatures.

Handling and Storage:

Handling: Handle carefully to avoid chipping, especially with larger targets, as composite materials can be brittle.

Storage: Store in a clean, dry environment, avoiding contamination that could impact thin-film purity.

Precautions: Avoid exposure to high humidity, as graphite is slightly porous and can absorb moisture, affecting performance.
