What processes can be used for customized experimental rotary tube furnaces?

The customized experimental rotary tube furnace, with its rotating heating, precise atmosphere control, and flexible customization characteristics, can support the following core processes:

1. Material synthesis and sintering
Ceramic material sintering
Uniform densification: By rotating heating to eliminate internal defects, high-purity ceramics (such as alumina ceramics with a density>3.9 g/cm ³) are prepared, suitable for electronic packaging substrates or bioceramics (such as dental implants).
Nanomaterial control: TiO2 nanoparticle with particle size of 10-20 nm is synthesized in an inert atmosphere, or nanometer powder with high specific surface area (>100 m2/g) is prepared by pyrolysis of sol gel method, which is used in the field of photocatalysis or sensors.
Preparation of composite materials: Mix aluminum powder with alumina particles and hot press sinter to obtain Al ₂ O ∝/Al composite materials with a density greater than 98%, improving wear resistance.
Metal material processing
Powder metallurgy: Sintering metal powder in a reducing atmosphere (such as hydrogen) to prepare high-strength alloy components.
Hot pressing: Optimizing the microstructure of metal based composite materials by combining rotary heating and pressure.

2. Heat treatment and performance optimization
Metal Annealing and Quenching
Eliminate internal stress under controlled atmosphere (such as hydrogen reduction environment), or adjust the microstructure through quenching to optimize mechanical properties (such as hardness and toughness).
Semiconductor material annealing
Repairing lattice damage after ion implantation in vacuum or inert atmosphere, activating impurity atoms, and improving device performance (such as the formation of silicon carbide “rivet points” in silicon-based solar cell negative electrode materials through ultrafast Joule heating, enhancing bonding strength).
Magnetic material processing
Adjust the crystal structure of soft/hard magnetic materials and optimize their magnetic properties (such as increasing permeability and coercivity).

3. Catalytic research and reaction testing
Catalyst synthesis and activation
Synthesize catalysts under specific atmospheres (such as oxidizing or reducing gases) and activate their activity through high-temperature treatment. For example, preparing Fe ∝ O ₄ catalyst by oxidizing pure iron sheets in an air atmosphere at 800 ℃, or obtaining high-purity copper catalyst by reducing copper oxide powder with hydrogen gas.
Catalytic performance evaluation
Conduct catalytic reaction tests in a tube furnace to analyze the activity, selectivity, and stability of the catalyst. For example, by using TGA combined technology to measure the pyrolysis residual carbon rate of polyethylene in N ₂ atmosphere, the influence of catalysts on carbon deposition behavior can be studied.

4. Development of new energy materials
Preparation of lithium-ion battery materials
Synthesis of positive electrode materials: calcining ternary materials or lithium iron phosphate at high temperatures to optimize electrochemical performance. For example, by controlling the thermal interaction between carbon and silicon phases through rotational heating, the phase separation problem in traditional heat treatment can be solved.
Negative electrode material treatment: Heat treat graphitized carbon materials or silicon-based negative electrode materials to improve cycling stability.
Waste battery recycling: Recycling valuable metals such as cobalt and nickel from waste lithium-ion batteries through heat treatment technology to achieve clean production.
Synthesis of Fuel Cell Materials
Preparation of proton exchange membranes or electrode catalysts under precise atmosphere control to optimize electrochemical performance.
Research on Solid Electrolytes
Testing the conductivity and stability of solid-state battery electrolytes at high temperatures to promote the development of solid-state battery technology.

5. High temperature and high pressure scientific research
Extreme condition simulation
Simulate the internal conditions of the Earth’s core or planet under high temperature and pressure conditions, and study the behavior of material phase transition, melting, etc.
Crystal growth control
By adjusting the temperature gradient and growth environment, directional growth of single crystal or polycrystalline materials (such as semiconductor crystals and optical crystals) can be achieved.

6. Material characterization and analysis
Thermogravimetric analysis (TGA)
Measure the mass change of the sample in a vacuum atmosphere or a specific atmosphere, and study the thermal stability, decomposition process, and redox reaction.
Differential Scanning Calorimetry (DSC) analysis
Combining TGA technology to measure the thermal changes of the sample during heating or cooling, and optimize the preparation process.
PHYSICAL PROPERTY TEST
Testing the thermal expansion, thermal conductivity, and thermal stability of materials at high temperatures provides key parameters for practical applications.

7. Environmental Engineering and Waste Management
pollutant degradation
Treating industrial waste at high temperatures or studying the decomposition mechanism of pollutants, such as using pyrolysis technology to decompose organic pollutants.
catalyst regeneration
Restore the activity of waste catalysts in a specific atmosphere and extend their service life.
