What Are the Applications of Tube Furnace?

The maximum operating temperature of open type vacuum tube furnace is 1200℃, and the maximum constant temperature gradient of the two temperature zones is 200℃. With high-purity quartz tubes and flanges, it can not only meet the temperature accuracy requirements of fine experiments, but also adapt to different batch sample processing scenarios. The application of open type vacuum tube furnace has deeply covered many fields such as new energy, semiconductor, ceramics, and scientific research in universities.

In the field of research and development of new energy materials, open type vacuum tube furnace is the main equipment for the preparation of lithium battery positive and negative electrode materials. The optional configuration of 1 or 2-inch quartz tube can be further adapted to different R&D scale requirements. Taking the sintering of ternary lithium, the cathode material of lithium-ion batteries, as an example, when developing small-batch formulas, a 1-inch quartz tube is selected, which can process 3 to 5 Φ20mm sample boats in a single time to accurately verify the process effects of different doping ratios. When the sample volume needs to be increased in the pilot phase, it can be replaced with a 2-inch quartz tube, and 8 to 10 sample boats can be placed at the same time to achieve a seamless connection from the small test certificate to the pilot amplification. In terms of technology, the first zone of the open type vacuum tube furnace is set to 900℃ for pre-burning of the precursor to remove moisture and impurities, and the second zone is set to 1100℃ to complete high-temperature sintering. The sample boat is slowly pushed from the low-temperature zone into the high-temperature zone. The whole process is carried out under the protection of argon gas, which can avoid material oxidation and improve the crystal integrity and electrochemical properties of ternary lithium.

In the field of scientific research and laboratory analysis in colleges and universities, open type vacuum tube furnace has become a priority choice for multi-disciplinary experimental teaching and basic research because of its flexible operation and adaptability to multiple types of samples. The switch of 1 or 2-inch quartz tube can meet the needs of different courses and research. In the high-temperature phase transition experiment of the materials science major, a 1-inch quartz tube is selected to observe the phase transition of small-volume metal samples at 550℃ in the first zone and 600℃ in the second zone. The process of grain growth can be visually demonstrated. The influence of temperature on the material structure. In the study of multi-step chemical reactions, for reactions that require two steps of different temperatures, the 2-inch quartz tube supports parallel experiments with multiple sets of samples, eliminating the need to build multiple devices, which helps to improve the experimental efficiency.

As can be seen from the above applications, the advantage of open type vacuum tube furnace lies not only in the process flexibility brought about by the independent temperature control and open structure of the dual temperature zone, but also in the adaptability of 1 or 2-inch quartz tubes and flanges, which can accurately meet the different needs of B-terminal buyers from small trials to pilot trials, from small volumes to batch samples. According to specific process requirements, we can recommend suitable quartz tube sizes and flange types for customers, and provide remote installation guidance and operation training to help the team quickly master the skills of equipment use.

If your team is facing the temperature control problem of a multi-step process, or needs a high-temperature equipment that can be flexibly adapted to different sample batches and meet strict sealing requirements, open type vacuum tube furnace is ideal for you.
