High-Purity Molybdenum Pellets for Thin-Film Deposition and High-Temperature Applications
Cell Lab 3N5 (99.95%) Molybdenum (Mo) Pellets are high-purity refractory metal evaporation materials engineered for vacuum coating, metallurgical, and semiconductor applications. With their outstanding thermal conductivity, creep resistance, and strength at elevated temperatures, these pellets deliver stable and reliable performance in extreme environments.
Molybdenum is widely used in furnace components, turbine parts, fusion and fission reactors, and forging dies. In thin-film coating, Mo provides excellent adhesion and wear resistance, forming a lubricating transfer layer that enhances surface durability. It is also a preferred material for semiconductor, optical, and sensor coatings due to its excellent evaporation characteristics under high vacuum.
High Purity (99.95%) – Reduces contamination for consistent film composition and superior conductivity.
Exceptional Thermal Stability – Withstands temperatures exceeding 2,600 °C without distortion or degradation.
High Conductivity and Strength – Ensures durable coatings and efficient energy transfer.
Excellent E-Beam Evaporation Compatibility – Stable under prolonged vacuum deposition.
Versatile Application Range – Ideal for refractory components, thin-film deposition, and high-stress environments.
