Gamma alumina(nano Al2O3) used in Nanofluid

  • September 28,2023.

Nanofluid, as a new type of efficient and high heat transfer performance energy transport working tool, can effectively improve the heat transfer performance of thermal systems, improve their efficiency, low resistance, and compact performance indicators, meet the high load heat transfer and cooling requirements of thermal systems, and meet the enhanced heat transfer requirements under some special conditions (microscale conditions). They have very broad application prospects and potential significant economic value in the field of enhanced heat transfer, It is called the future cooling and heat dissipation technology. It is a composite material formed by suspending nanoparticles in a basic fluid. The nanoparticles can be materials with special properties and functions, such as alumina nanoparticles. Gamma alumina is a common crystalline phase of alumina with high surface area and activity. The following are several main effects it plays on nanofluids:


1. Increasing the stability of nanofluid: The nanoparticles of gamma alumina have a high surface area and activity, which can stabilize nanomoids through molecular interaction with basic fluids. Nano particles can prevent the condensation and settlement of particles through surface charge, Van Dehua and static repulsion forces, thereby maintaining a uniform dispersing state of nanotoscope.

2. Increasing thermal conductivity: Gamma aluminum nanoparticles have good thermal conductivity, which can improve the overall heat conductivity of nanofluid. By suspending the gamma aluminum nanoparticles in the basic fluid, the thermal conductivity can be increased, thereby improving the cooling effect and thermal management performance.

3. Improving anti-friction performance: Gamma alumina nanoparticles have good abrasion resistance and lubrication effects, and can play a role in reducing friction and wear in nanofluid. Applying gama alumina nanofluid to the lubrication system can reduce friction loss, reduce energy consumption and extend the service life of mechanical parts.

4. Enhancing the performance in catalytic reactions: Gamma alumina nano particles can provide more active surface and reaction sites to enhance the efficiency and selectivity of catalytic reactions. Hanging gama alumina nanoparticles in nanofluid can improve the dispersability and stability of the catalyst, thereby improving the performance of catalytic reactions.


Hanging gamma alumina nanoparticles can form alumina nanofluids in the basic fluid. Its special nature makes it show extensive application potential in multiple areas, including:

1. Nano fluid cooler: Alumina nanofluid has a high thermal conductivity and large surface area, which can be used to create an efficient cooling system. In high -temperature equipment such as electronic devices, motors, and engines, the use of alumina nanofluid cooler can improve thermal conductivity efficiency, lower temperature, and extend the life of the equipment.

2. Subcreasing reduction agent: alumina nanofluid can be used as lubricant to reduce friction and wear. Applying it to mechanical systems can reduce energy loss, improve efficiency, and extend the service life of parts.

3. Nano -catalyst carrier: alumina nanoparticles in nanofluids can be used as carriers of catalysts. It has a large active surfaces, which can increase the effective response surface area, and provide better quality transmission performance and thermal stability in the catalytic response.

4. Sensor Application: With the special nature of alumina nanofluid, sensors can be prepared with high sensitivity. For example, in the field of gas -sensitive sensors, aluminum nanoparticles suspended in the basic fluid can improve the detection sensitivity and response speed of the sensor to specific gas.
