Lead Granules (+30 mesh) 99.99%
Lead Granules with the highest possible density and smallest possible average grain sizes for use in Chemical Vapor Deposition (CVD) and Physical Vapor Deposition (PVD) processes including Thermal and Electron Beam (E-Beam) Evaporation, Low Temperature Organic Evaporation, Atomic Layer Deposition (ALD), Metallic-Organic and Chemical Vapor Deposition (MOCVD). Our standard granules are amorphous uniform pieces in sizes ranging from < 1 mm, 1-2 mm, and 3-5 mm. Materials are produced using crystallization, solid state and other ultra high purification processes such as sublimation.
