Ag (Silver) Pellets are high-purity evaporation materials used in thin-film deposition for applications requiring excellent electrical conductivity, reflectivity, and antibacterial properties. Silver thin films are widely applied in industries such as electronics, optics, photovoltaics, and medical devices due to their outstanding performance in terms of conductivity and reflectivity.

Application

1. Electronics: Silver is used in thin-film circuits, contacts, and electrodes because of its superior electrical conductivity. It’s a key material in capacitors, resistors, and printed circuit boards (PCBs).

2. Optics: Silver films are commonly used as reflective coatings on mirrors, lenses, and other optical components, due to their excellent reflectivity across the visible spectrum.

3. Photovoltaics: Ag thin films are crucial in solar cell production, particularly in silver paste contacts for improving conductivity and efficiency in solar panels.

4. Medical Devices: Silver’s antibacterial properties make it ideal for coatings on medical devices to prevent bacterial growth and infections.

5. Antennas and Sensors: Silver coatings are used in antennas and various sensors due to their high conductivity, ensuring minimal signal loss.

6. Jewelry and Decorative Coatings: Silver films are used in thin coatings for jewelry and decorative items to give a bright, reflective finish.
