Name

molybdenum boat is a vessel or container made from molybdenum, a chemical element with the symbol Mo and atomic number 42. Molybdenum is a refractory metal known for its high melting point, excellent thermal conductivity, and resistance to corrosion.

Molybdenum boats are commonly used in various high-temperature applications, particularly in the field of materials science and manufacturing. They are often employed as crucibles or carriers for materials that need to be heated at extremely high temperatures or subjected to controlled thermal environments.

 molybdenum boat  applications
  1. Thin Film Deposition: Molybdenum boats are often employed in physical vapor deposition (PVD) processes, such as thermal evaporation or electron beam evaporation. The boats hold the material to be evaporated, such as metals or compounds, and are heated to high temperatures, causing the material to vaporize and condense onto a substrate to form thin films.
  2. High-Temperature Furnaces: Molybdenum boats are used as sample holders, crucibles, or containers in high-temperature furnaces. These furnaces are employed for various heat treatment processes, such as annealing, sintering, or crystal growth, where the molybdenum boats can withstand extreme temperatures without reacting or melting.
  3. Powder Metallurgy: Molybdenum boats are utilized in powder metallurgy processes to hold powdered materials during sintering or hot isostatic pressing (HIP). The boats ensure that the powder is contained and heated uniformly, facilitating the densification and bonding of the particles.
  4. Semiconductor Industry: Molybdenum boats find application in the manufacturing of semiconductors, particularly for processes like chemical vapor deposition (CVD) or metal-organic vapor phase epitaxy (MOVPE). They provide a stable platform for holding the precursors or substrates at elevated temperatures during these fabrication processes.

Molybdenum boats are favored due to their high-temperature stability, low vapor pressure, and resistance to chemical attack. They are available in various sizes and shapes, such as rectangular, cylindrical, or custom designs, to suit different experimental or industrial requirements.
