It is suitable for vacuum sintering of tungsten and molybdenum products.
Principle
The 2200 ℃ Tungsten Vacuum Furnace uses tungsten as the hot zone construction material due to its exceptional properties, including high melting point, low vapor pressure, high hot strength, low thermal expansion, high thermal conductivity, high Young's modulus, high corrosion resistance, and good electrical conductivity. These properties ensure the furnace's durability and performance even at extremely high temperatures. The vacuum environment created within the furnace allows for precise temperature control and prevents contamination of the materials being processed. The furnace's design and construction enable it to achieve temperatures of up to 2200 ℃, making it suitable for various applications in materials research and industrial processes.
Advantages
- High temperature resistance: Tungsten has a melting point of 3420ºC (6187ºF), making it ideal for use in high-temperature applications.
- Low vapor pressure: Tungsten has a low vapor pressure, which means that it will not evaporate at high temperatures.
- High hot strength: Tungsten has a high hot strength, which means that it can withstand high loads at high temperatures.
- Low thermal expansion: Tungsten has a low thermal expansion, which means that it will not expand or contract significantly with changes in temperature.
- High thermal conductivity: Tungsten has a high thermal conductivity, which means that it can conduct heat quickly and efficiently.
- High Young's modulus: Tungsten has a high Young's modulus, which means that it is stiff and resistant to deformation.
- High corrosion resistance: Tungsten has a high corrosion resistance against acids and molten metals, making it ideal for use in corrosive environments.
- Recrystallization temperature: Tungsten has a recrystallization temperature between 1100º – 1400ºC (2012º – 2550ºF), which means that it can be annealed to improve its mechanical properties.
- Good electrical conductivity: Tungsten has a good electrical conductivity, making it suitable for use in electrical applications.
- High modulus of elasticity: Tungsten has a high modulus of elasticity, which means that it is resistant to bending and deformation.
Safety Advantage
- Kindle Tech vacuum furnace owns over current protection, over temperature alarming function, furnace will turn off the power automatically
- Furnace build in thermal couple detecting function, furnace will stop heating and alarm will be on once broken or failure detected
- Power failure restarting function,furnace will resume the furnace heating program when power is incoming after failure

Warnings
Operator safety is the top important issue! Please operate the equipment with cautions. Working with inflammable& explosive or toxic gases is very dangerous, operators must take all necessary precautions before starting the equipment. Working with positive pressure inside the reactors or chambers is dangerous, operator must fellow the safety procedures strictly. Extra caution must also be taken when operating with air-reactive materials, especially under vacuum. A leak can draw air into the apparatus and cause a violent reaction to occur.
