What are the application scenarios and industries of bell jar furnaces?

As a high-temperature sintering furnace, the bell jar furnace has a wide range of application scenarios and industries. The following is a detailed summary of its application scenarios and industries:
Application scenarios
Material sintering:
Ceramic sintering: When sintering ceramic materials, the bell jar furnace can conveniently load and unload sintering plates or molds, ensuring the smooth progress of the sintering process.
Metal sintering: During the sintering process of metal materials, a bell jar furnace can control the heating temperature and atmosphere to achieve the desired sintering effect.
Powder metallurgy: In the powder metallurgy process, materials are usually loaded into the furnace in powder form, and the bottom opening design of the bell jar furnace facilitates the filling and removal of powder.
Heat treatment:
For applications that require controlling the atmosphere during heat treatment, the design of a bell jar furnace helps to better control and maintain the atmosphere inside the furnace.
During the annealing process of metal materials, the design of the bell jar furnace can reduce thermal shock and avoid material deformation.
Chemical Vapor Deposition (CVD):
During the CVD process, a bell jar furnace helps to achieve uniform gas flow and deposition, ensuring the uniformity and quality of the deposited layer.
Crystal growth:
When growing single crystal or polycrystalline materials, a bell jar furnace can conveniently place and remove the crucible used for crystal growth.
Electronic component manufacturing:
