4N (99.99%) Platinum (Pt) Pellets Evaporation Materials
Introduction:
Platinum evaporation materials refer to solid substances primarily composed of platinum and engineered for use in thermal evaporation processes. These materials typically come in various forms, such as pellets, rods, wires, or sheets, suitable for vaporization in vacuum environments.
During the thermal evaporation process, the solid platinum material is heated to its vaporization temperature, causing it to transition directly from a solid to a vapor state. The vaporized platinum then condenses onto a substrate surface, forming thin films or coatings with desired properties.
Platinum evaporation materials find applications in various industries due to platinum’s unique properties, such as high melting point, excellent corrosion resistance, and catalytic activity. They are commonly used in electronics, catalysis, and laboratory research for purposes such as thin film deposition, surface coating, and material analysis.
