Product Description

Hot Zone

Our hot zones are designed for temperatures between 1 **0 °C (1 **2 °F) and 2 **0 °C (5 **2 °F).

We are reliable and competitive manufacturers of thermal processes: whether in high vacuum, protective gas atmospheres.

Regularly developing hot zones for new thermal processes in collaboration with system engineers and users. And precisely in growth sectors such as sapphire or silicon crystal growing, it is important for us to work with you right from the development phase in order to come to the optimum solution.

Tungsten/molybdenum crucible

Since the melting point of tungsten has reached ***0°C, and molybdenum is ***0°C. For sapphire crystal growth furnace, high-purity, high- density, no internal -crack tungsten/molybdenum crucible with other features of exact measurement and smooth surface has decisive influence on success ratio of seed growth, quality control of pulling crystal, metamictization pot-committed and service life during sapphire growth process.

Molybdenum sheet

After rolling and processing with deflection reaching *0% , the density of molybdenum sheet basically comes close to molybdenum’s theory density. Therefore, molybdenum sheet possesses the properties of high density, balanced internal structure and excellent high creep strength temperature. Molybdenum sheet is widely used in reflection shield, cover plate applied in the sapphire growth furnace, reflection shield, heating tape, connecting pieces applied in vacuum furnace

Molybdenum reflection shield

As the heat-shield parts in the sapphire growth furnace, the most decisive function of molybdenum reflection shield is to prevent and reflect the heat in the furnace. Heat-shield parts with high-density, exact-measurement, smooth-surface, convenient-assembly and reasonable-design has great significance in improving the crystal-pulling.

Upper and bottom cover plate

As the heat-shield parts in the sapphire growth furnace, the most decisive function of upper and bottom cover plate is to prevent and reflect the heat in the furnace. Heat-shield parts with high-density, exact-measurement, smooth-surface, convenient-assembly and reasonable-design has great significance in improving the crystal-pulling
