Palladium Silver Alloy

Palladium Silver Alloy sputtering targets are sputtering targets made of an alloy consisting of palladium and silver, which have excellent physicochemical properties and are used in important applications in electronics and chemicals.

Characteristics

Density: Typically between 11.2 – 11.5 g/cm3, this high density gives the target good stability and material transport properties during sputtering.

Melting point: between 1280°C and 1475°C. The high melting point ensures that the target is stable and has good substance transport properties during sputtering. The high melting point ensures that the target can withstand high energy inputs during the sputtering process without melting and deformation, which is conducive to maintaining the stability and uniformity of sputtering.

Hardness: Vickers hardness is generally between 736 – 883MPa, the higher hardness makes the target material has better wear resistance and deformation resistance, can maintain a better shape and surface flatness in the sputtering process, so as to ensure the quality of sputtered film.

Antioxidant properties: good oxidation resistance at room temperature, which increases with the palladium content at high temperatures. This makes the target less susceptible to oxidation during storage and use and maintains good chemical stability.

Corrosion resistance: it can be dissolved by nitric acid and corroded by cyanide, but it does not change colour in sulphur-containing atmosphere, so it has certain corrosion resistance.

Hydrogen Absorption and Transmission Performance: It has strong hydrogen absorption ability and selective hydrogen transmission ability, and the purity of hydrogen filtered by it can reach 99.99999%, which is a characteristic that makes it potentially valuable in certain applications that have high requirements for hydrogen purity.

Resistivity: The resistivity of the alloy varies depending on the ratio of palladium to silver. Palladium has a relatively high resistivity and silver has a relatively low resistivity. By adjusting the ratio of the two, it is possible to obtain Palladium-Silver alloy sputtering targets with specific resistivities to meet different electrical performance requirements.

Conductive properties: As silver has good conductive properties, palladium silver alloys also have good conductive properties to a certain extent, which makes the thin films formed by sputtering have good conductive properties in areas such as electronic devices.
