Tungsten boat Evaporator boat

PRODUCT DETAILS

Tungsten boat

Tungsten boat is made from Tungsten sheet through a process of cutting, bending, welding and riveting. We can manufacture customized products according to your requirements.Our evaporation boats offer a good level of electrical conductivity and possess low vapor pressures combined with a very high melting point. When powered on, our boats heat the material for evaporation. During this process, the low vapor pressures of our metals ensure that no tungsten, tantalum or molybdenum particles enter the vapor and penetrate the subsequent layer.

The furnace industry has seen a remarkable growth in the production of custom-made, high temperature vacuum or argon atmosphere furnaces for growing sapphire crystals used in manufacturing of LEDs. These furnaces have unique and demanding hot zone designs for melting alumina in crucibles for precise, highly controlled crystal growth.

Mingguan is fully aware of the various sapphire crystal growing methods and supplies components to the customers accordingly.

The hot zones in sapphire growing furnaces use our molybdenum and tungsten products for furnace components and fixtures. These high temperature materials are characterized by their high thermal and electrical conductivity, low coefficient of thermal expansion, and excellent strength and stability at temperatures above 2,000°C.
