Tungsten Bracket For Sapphire Furnace

Tungsten bracket is made of pure tugsten which is also called tungsten support or holder for setting ungsten crucible. The shape of tungsten bracket is always round with hole in the middle. The purity of tungsten bracket is over 99.95%, and its density is about 18.2g/cm3, which can be the same as tungsten crucible and tungsten crucible cover.

Tungsten crucible connected with tungsten bracket and tungsten crucible cover is a set of products in the middle of sapphire growth furnace. All these products are sintered and smoothed. Tungsten crucible cover and tungsten bracket can also be polished, which is showing the bright and smooth surface.

Excellent High-Temperature Performance: Tungsten has a very high melting point (3420°C), so it can withstand the extreme heat needed for sapphire growth, usually above 2200°C. Even at such high temperatures, the tungsten bracket remains strong and stable without warping or breaking.

Low Contamination Risk: Tungsten releases very little vapor at high temperatures, reducing its impact on sapphire crystal growth. This helps maintain the purity and quality of the sapphire crystals.

Strong Mechanical Properties: Tungsten is hard, strong, and wear-resistant. It can handle mechanical stress and friction, ensuring stability in the demanding conditions of a sapphire furnace and extending its service life.

Low Thermal Expansion: Tungsten expands very little when heated, so its size stays nearly the same even with temperature changes. This makes it ideal for sapphire growth, where precise temperature and size control are crucial.

High Customizability: The shape, size, and structure of the tungsten bracket can be customized to fit different furnace designs and process requirements, meeting specific application needs.

Sapphire Crystal Growth: In sapphire growth furnaces, the tungsten bracket supports and secures key components like tungsten crucibles and heating elements. For example, in the Vertical Gradient Freeze (VGF) method, it ensures crucible stability, making crystal growth smoother and improving both quality and yield.

Semiconductor Manufacturing: Besides sapphire growth, tungsten brackets are also used in other high-temperature processes, such as diffusion or Chemical Vapor Deposition (CVD) in semiconductor production. They provide stable high-temperature conditions and structural support for these processes.
