Tungsten boats, also known as evaporation boats or coated tungsten boats, are mainly used in a variety of vacuum coating industries, including but not limited to gold plating, evaporators, development tubes, heating vessels, electron beam painting and other applications. In addition, in the sintering furnace sintering or vacuum annealing industry, tungsten boat also plays an important role. In these industries, tungsten boats are widely used as resistance evaporation sources due to their excellent high temperature resistance, good electrical and thermal conductivity, and stable chemical properties.
The specific use of tungsten boat is usually to make it into a ship-type part, connect the two ends of the part through a wire, and then put metal with a low melting point in the middle of the concave position. In the case of electricity, the temperature of the tungsten boat can rise to about 2000 degrees, so that the metal evaporates into gas, and then plated on the surface of the workpiece.
In addition, due to the wear resistance and corrosion resistance of tungsten boat, it is also widely used in the picture tube, mirror making, toys, household appliances, mobile phones, electrical shell and other electronic industries.
Please note that due to the thin wall thickness of the tungsten boat and the high temperature of its working environment, it is easy to deformation, which may affect its use effect. Therefore, when using tungsten boat, it is necessary to pay attention to control its working environment and conditions to prevent its deformation.
In general, tungsten boat has a wide range of applications in many industrial fields, is an important material in vacuum coating and vacuum annealing industries.
