Tungsten Evaporation Boats

In the vast landscape of modern science and industry, the tungsten boat emerges as a remarkable tool with diverse and crucial applications.

Tungsten boats are crafted from tungsten, a metal known for its exceptional properties. Tungsten has an incredibly high melting point, excellent thermal conductivity, and remarkable resistance to chemical reactions. These qualities make it the ideal material for creating vessels that can withstand extreme conditions.

One of the primary applications of tungsten boats is in the field of vacuum deposition. Here, the boat is heated to high temperatures within a vacuum chamber. Materials placed on the boat vaporize and deposit onto a substrate, forming thin films with precise thickness and composition. This process is essential in the manufacturing of semiconductors. For instance, in the production of microchips, tungsten boats help deposit layers of materials like silicon and metals, creating the complex circuitry that powers our digital world.

In the realm of optics, tungsten boats play a vital role. They are used to deposit coatings on lenses and mirrors, enhancing their reflectivity and transmissivity. This leads to improved performance in optical devices such as cameras, telescopes, and laser systems.

The aerospace industry also benefits from tungsten boats. Components exposed to high temperatures and harsh environments during space travel are fabricated using the controlled deposition facilitated by these boats. Materials deposited in this manner provide superior heat resistance and durability.

Tungsten boats are also employed in the development of new materials for energy storage and conversion. They assist in the synthesis and characterization of materials for batteries and fuel cells, driving the search for more efficient and sustainable energy solutions.

In material science research, they enable the study of phase transitions and the properties of substances under controlled evaporation conditions. This helps scientists understand and manipulate the behavior of materials at the atomic level.

Furthermore, in the production of specialized coatings for various industrial applications, tungsten boats ensure the uniform and precise application of materials, enhancing the performance and longevity of the coated surfaces.

The tungsten boat is an indispensable component in numerous cutting-edge technologies. Its ability to facilitate controlled material deposition and evaporation makes it a key enabler of progress in multiple fields, shaping the future of science and industry.

Our standard product range

We produce evaporation boats made of molybdenum, tungsten, and tantalum for your application:

Tungsten evaporation boats
Tungsten is highly corrosion-resistant compared with many molten metals and, with the highest melting point of all metals, is extremely heat-resistant. We make the material even more corrosion-resistant and dimensionally stable by means of special dopants such as potassium silicate.

Molybdenum evaporation boats
Molybdenum is a particularly stable metal and is also suitable for high temperatures. Doped with lanthanum oxide (ML), molybdenum is even more ductile and corrosion-resistant. We add yttrium oxide (MY) to improve the mechanical workability of molybdenum

Tantalum evaporation boats
Tantalum has a very low vapor pressure and a low evaporation speed. What is most impressive about this material, however, is its high corrosion resistance.

Applications:
Tungsten boats are widely used in vacuum coating industries or vacuum annealing industries such as gold plating, evaporators, video tube mirrors, heating containers, electron beam painting, household appliances, consumer electronics, semiconductors and various decorations. Note: Due to the thin wall thickness of the tungsten boat and the high temperature of its working environment, it is easy to deform. Generally, the wall of the boat is bent and deformed into the boat. If the deformation is serious, the product will not be able to continue to be used.
