Tungsten Heater
Tungsten heater is made of tungsten wire, which is the heating source of sapphire growth. It plays a decisive role in the formation of solution turbulence and longitudinal temperature tilt.
Tungsten Heating Element
Tungsten heating element is of great significance to the quality control of sapphire crystal and it can prolong the service life of the products. The purity of tungsten heating element is no less than 99.95%. The density of the tungsten heating element is higher than 19.1g/cm3. The application ambient temperature shall not exceed 2400 ℃. Our company can produce tungsten heating elements according to customers' drawings.Tungsten Mesh Heater
Tungsten mesh heater element is a bit complicated in chip design and has more advantages than other types of heaters. It has good surface thermal effect and smooth thermal distribution. The temperature of the furnace can be maintained good consistency during operation. The resistance value of heater element in tungsten mesh heater is designed for easy control. Thus electric current and voltage are easy to control within a reasonable range and cost. Damage and shape change are not easy to cause by assembly adjustment. The repair and maintenance are very convenient. If there is occasional break of tungsten wire, the total resistance value will not be changed, and the normal use will not be affected.Tungsten Shield
As an auxiliary tool, tungsten shield is used for furnace insulation and is widely used in crystal growth furnace. It helps to coordinate the consistency, efficiency and energy consumption in hot zones. It can also be applied in optical equipment. The maximum working temperature of tungsten shield is 2450 ℃, which can be used in vacuum and reducing gas. In general, the design thickness of tungsten shield is 0.5mm to 2.5mm. The thicker it is, the longer its service life will be. Tungsten shield can be used in a solid and rough environment, and it has high reflection of a smooth surface.Tungsten Shelf
Tungsten shelf is used in high temperature vacuum furnace, such as vacuum annealing furnace, vacuum sintering furnace and hot-pressing furnace. Tungsten shelves are heavy and fragile. Because of its high melting point, tungsten shelves are very resistant to high temperature. We can provide tungsten shelves according to customers' needs. Tungsten shelf can be made by riveting or welding. The highest working temperature of tungsten shelf is 2450 ℃, which can be used in vacuum and reducing gas. After annealing treatment, its purity can reach 99.97%Tungsten Tray
Tungsten tray is used to support tungsten crucible and sapphire growth furnace. We use tungsten with purity over 99.95% to make tungsten trays. Tungsten trays are heavy and fragile. Its melting point is 3410 ℃. Tungsten tray has high density and excellent machining property. It is usually made by riveting and welding process. The highest working temperature of tungsten tray is 2400 ℃, which will be used in vacuum and reducing gas. Our products are annealed.Tungsten Strip Heater
Tungsten strip heater is widely used in high temperature vacuum furnace. Its operating temperature is between 1800 ℃ and 3000 ℃. Tungsten strip heater can also be used for heating elements of MOCVD equipment. It has the characteristics of high temperature resistance, high arc resistance, excellent electrical conductivity, high thermal conductivity and low thermal expansion. Tungsten strip heater also has features of good mechanical properties, heat resistance, excellent uniformity and low deformation.If you would like to purchase tungsten heater from China, please don't hesitate to Contact Us.
