Molybdenum Plates, Sheets, and Foils
Molybdenum plates are made by rolling pressed and sintered molybdenum billets. Plates with a thickness of 2-30 mm are referred to as molybdenum plates, 0.2-2 mm as molybdenum sheets, and below 0.2 mm as molybdenum foils. Different thicknesses require different rolling mills. Thin sheets and foils have good flexibility and can be produced as coils using tension rolling mills, commonly called molybdenum strips.
Properties of Molybdenum Boats
Key Applications
Vacuum Evaporation and Deposition
Molybdenum boats are used in vacuum evaporation processes where materials are heated until vaporized and then condensed onto substrates to form thin films. Their high melting point and thermal stability prevent deformation or contamination, essential for producing semiconductors, solar cells, and optical coatings.Sintering and Metal Melting
Used in powder metallurgy, molybdenum boats facilitate sintering and metal melting by heating powders to near their melting point to create solid materials. Molybdenum’s heat resistance and minimal reactivity with most metals make it ideal for high-performance alloy and precision component production.Chemical Vapor Deposition (CVD)
Molybdenum boats serve as containers for precursor materials in CVD processes, producing high-purity and high-performance coatings or films. Their stability ensures the purity of the deposited materials, making them suitable for semiconductor manufacturing, coating tools, and producing nanomaterials.Annealing and Heat Treatment
In annealing processes, materials are heated and cooled to relieve stress and improve ductility. Molybdenum boats hold and transport materials through annealing furnaces, withstanding prolonged exposure to high temperatures without degradation, making them essential for thermal processing of metals and alloys.Crystal Growth
Molybdenum boats are used to hold raw materials during the growth of single crystals, such as silicon or sapphire, for semiconductor and optical applications. Their high-temperature resistance and inertness ensure the production of high-purity, defect-free crystals.Laboratory Applications
Molybdenum boats are reliable containers for high-temperature experiments in material research and thermal analysis, thanks to their durability and chemical resistance, even in corrosive environments.
