Tungsten boats and molybdenum boats are mainly used in the vacuum coating industry and the boat boxes in vacuum furnaces. According to the different production processes and uses, tungsten boats and molybdenum boats can be divided into stamping boats, welding boats, and riveted boats. Stamping boats can also be called evaporation boats or coating boats, which are formed by high-temperature stamping of tungsten or molybdenum sheets. Welding boats and riveted boats are formed by bending tungsten plates or molybdenum plates and then welding or riveting. Coating boats can be supplied in regular sizes and customized sizes, and riveted or welded boats can be processed according to customer drawings.
1. Overview
Both tungsten boats and molybdenum boats are tools for burning metals, usually used in various heat treatment and metal processing processes. Tungsten and molybdenum have similar physical and chemical properties, such as high melting point, high strength, high hardness, low vapor pressure, high temperature resistance, strong creep resistance, good electrical and thermal conductivity, wear resistance, corrosion resistance, and long service life.
2. Material Difference
Tungsten boats are made of tungsten metal, while molybdenum boats are made of molybdenum metal. Tungsten is a high-melting-point metal that can still maintain its shape at high temperatures, so tungsten boats are usually used to burn high-temperature materials. In contrast, molybdenum boats are more suitable for the burning process of certain materials because molybdenum can show excellent physical properties at high temperatures.
3. Difference in use
Tungsten boats are usually used in melting experiments at extremely high temperatures, such as high-temperature casting, sintering, and vacuum distillation of metals and glass. At the same time, tungsten boats are also often used in the electronics industry, aerospace and other fields. Molybdenum boats are more suitable for burning metals with medium and low melting points, and are widely used in semiconductors, vacuum furnaces, and heat treatment. And it is also more suitable for experiments at lower temperatures, such as solid-state reactions, semiconductor processes, solar cell production and other more common experiments.
