As a typical product of transition metal tungsten, the tungsten boat you buy, also known as evaporation boat, evaporative tungsten boat, or coated boat, is made of tungsten sheet by welding or high-temperature stamping, which is an important sintering carrier for tungsten powder preparation.
Because the tungsten content is as high as 99.95%, the tungsten boat has extremely similar physical and chemical properties to the metal tungsten.
In terms of physical and chemical properties, the evaporation boat has a high density (19.35g / cm ³）， High melting point, high strength, great hardness, low evaporation rate, low vapor pressure, high-temperature resistance, wear resistance, corrosion resistance, and good electrical and thermal conductivity.
According to different uses, there are many kinds of tungsten boats you buy, including stamping boats, folding boats, welding boats, riveting boats, etc. In addition, in the process of practical application, we also need to pay attention to its size. The boat with model #207 has a thickness of 0.2mm, a width of 7mm, and a length of 100mm; The #215 tungsten boat has a thickness of 0.2mm, a width of 15mm, and a length of 100mm; The #308 boat has a thickness of 0.3mm, a width of 8mm and a length of 100mm; The #310 boat has a thickness of 0.3mm, a width of 10mm and a length of 100mm.
From the perspective of production technology, the evaporation boat can be prepared by welding, that is, heating and pressurizing the tungsten plate under high-temperature conditions to melt its joints together, and then welding. After welding, it can be cooled to obtain the required products. The tungsten boat manufactured by this method has good high-temperature resistance.
In terms of application, tungsten boats you buy are widely used in vacuum coating industries or vacuum annealings industries such as gold plating, evaporators, picture tube mirrors, heating containers, electron beam painting, household appliances, and consumer electronics, semiconductors, and various decorations.
Note: due to the thin wall thickness and its high working environment temperature. Therefore, it is easy to deform. Generally, the boat wall bends and deforms into the boat. If the deformation is serious, the product will not be able to continue to use.
