What is a molybdenum boat?

A molybdenum boat is a container used in high-temperature vacuum and inert gas environments, primarily for evaporating or depositing materials. Here are some key characteristics and applications of molybdenum boats:

Characteristics:
High Melting Point: Molybdenum has a melting point of approximately 2620°C, enabling molybdenum boats to operate at high temperatures.

Excellent Thermal Conductivity: Molybdenum boats possess excellent thermal conductivity, effectively transferring heat.

Corrosion Resistance: Molybdenum exhibits good corrosion resistance to many chemicals, making it suitable for various chemical environments.

Mechanical Strength: Molybdenum boats possess high mechanical strength, capable of withstanding high temperatures and pressures.

Applications:
Thin Film Deposition: In the semiconductor and optoelectronic industries, molybdenum boats are commonly used to evaporate metals such as aluminum, nickel, and tungsten to form thin films.

Material Evaporation: Used to manufacture high-purity metals and alloys.

Vacuum Heat Treatment: Molybdenum boats can heat and process materials in a vacuum environment, improving material properties.

Due to their excellent high-temperature performance and chemical stability, molybdenum boats are widely used in high-tech fields.
