Tungsten boats are crucial components in high-temperature furnaces, vacuum systems, and semiconductor manufacturing. Made from high-purity tungsten, these boats are designed to withstand extreme temperatures while maintaining structural integrity. Their unique properties make them ideal for processes like evaporation, material deposition, and thermal treatment, where other materials would degrade under the intense conditions.
Product Description
Tungsten boats are often used in industries requiring high temperatures, such as in material evaporation processes, chemical vapor deposition (CVD), and semiconductor manufacturing. These boats are specially crafted from high-purity tungsten, offering superior heat resistance and durability. Tungsten boats can be customized to meet specific requirements, with various sizes, shapes, and configurations available.
With excellent thermal conductivity and resistance to oxidation, tungsten boats provide an ideal solution for demanding applications. The high melting point of tungsten (3,422°C) ensures that these boats maintain their structural integrity even under extreme conditions, making them highly reliable in both vacuum and inert atmospheres.
