Tungsten Boats Evaporation Boats for Vacuum Metalizing

As a high performance materials, Pure Tungsten has high melting temperature, high density, low vapor pressure, low thermal expansion combined with good thermal conductivity, sufficient electrical resistance, high modulus of elasticity.

Tungsten boat is widely used in metallizing, electron-beam spraying as well as sintering and annealing in reducing atmosphere in electronics and light industries. Manufactured by the special production line in our corporation, tungsten boats can provide reliable guarantee of product quality for the users by adopting excellent tungsten materials with high purity, advanced techniques as well as special treatment to the product surfaces.

Tungsten boats are mainly used for evaporation or metalization of Al, Ni, Cu, Ag and many other metals in vaccuum furnaces.

Features of tungsten boats are as follows

1. High Melting Point: Tungsten has the highest melting point among all metals, reaching about 3422°C (6192°F), hence allowing tungsten boats to be used in extremely high-temperature atmospheres.

2. Thermal Conductivity: Good thermal conductivity of tungsten allows a corresponding efficient heat transfer to the materials treated/ processes.

3. Strength: The tungsten boats are strong, resistant to mechanical stresses, meaning they cannot easily deform or break down during heating and cooling cycles.

4. Resistance to Corrosion: Fungine boats against the corrosion of many acids and bases; therefore, it is suitable for a wide variation in chemical atmospheres.

Features Of Tungsten Boats Are As Follows

Applications of tungsten boats

The tungsten boats participate in several processes, especially of the physical vapor deposition type, serving as receptacles for materials under evaporation with the intent of depositing thin films onto substrates.

Semiconductor Manufacturing: Tungsten boats provide a support structure for wafers during many varied high-temperature processing steps in semiconductor manufacturing, including diffusion or annealing.

Another prevalent technique used for depositing materials is: CVD-Chemical Vapor Deposition: The substrates to be coated can be placed on the tungsten boats while performing CVD at which the deposition of films takes place in the form of chemical reactions at a very high temperature.

High-Temperature Sintering: They are involved in operations of sintering for ceramics at such high temperatures, since heat needs to bond the particles together.
