What Is the Purpose of a Tube Furnace?

Open type vacuum tube furnace relies on a maximum operating temperature of 1200℃, an independent and controllable dual temperature zone design, and a multi-specification quartz tube and flange sealing structure adapted to 60mm/80mm/100mm. It has become a device that can meet the heating needs of multiple scenes. The use of open type vacuum tube furnace is not limited to a single high-temperature heating, but revolves around material preparation, modification, and testing under precise temperature control, covering the whole process from laboratory small-batch research and development to industrial pilot testing, and providing stable and reliable heating environment support for technological breakthroughs in different fields.

In the field of materials science research and development, open type vacuum tube furnace is an important tool for realizing the synthesis and structural modification of multiple materials. The dual-temperature zone design of open type vacuum tube furnace can form an axial gradient temperature field in the quartz tube to meet the special needs of different material synthesis for temperature zoning. For example, in the preparation of nanomaterials, researchers can set one end of the quartz tube to 1000 to 1200℃ for the thermal decomposition of the precursor, and the other end to 600 to 800℃ for the in situ growth of nano-particles. Particle size and morphology are controlled by temperature gradient. In the preparation of ceramic matrix composites, the temperature difference between the two temperature zones can be used to realize the gradient infiltration of the fiber prefab and the matrix, and the interfacial reaction defects can be reduced. In addition, the adapted flange sealing structure allows a vacuum environment or an inert gas atmosphere to form in the quartz tube to avoid the material from being oxidized at high temperatures. In the preparation of metal oxide films, high-temperature annealing under vacuum conditions can remove residual impurities in the film and improve the crystallinity and electrical conductivity of the film. A materials laboratory of a university used open type vacuum tube furnace to successfully prepare a titanium dioxide nanotube array with uniform particle size. The photoelectric conversion efficiency of the array is significantly improved compared with the samples prepared by traditional single-temperature zone heating equipment, and the advantages of dual-temperature zone design in material synthesis are verified.

In addition, open type vacuum tube furnace also plays an important role in the fields of chemical catalysis and metal heat treatment. In the study of catalytic reactions, open type vacuum tube furnace can use the dual-temperature zone design to realize the partitioning of catalyst activation and reactant reaction to improve catalytic efficiency. In metal heat treatment, open type vacuum tube furnace can eliminate the internal stress of metal materials and improve the mechanical properties of materials through vacuum and high temperature annealing.
