Nanocrystalline cores can be classified as Common Mode Choke Cores (CMC), High Frequency Power Transformer Cores (HFPT) and Current Transformer Cores (CT) based on different uses and performances.
According to the magnetic properties of cores, selecting suitable compositions, the nanocrystalline ribbon is wound into cores of various shapes and sizes, such as toroidal, rectangular, C-shape or E-shape, etc. After specific heat treatment process, cores with required magnetic properties will be produced and encapsulated in accordance with customers' requirements.Get more news about Nanocrystalline core,you can vist our website!
Compared with ferrite, nanocrystalline has higher Curie temperature, wide working temperature range and excellent thermal stability. It has higher magnetic permeability and higher saturation flux density, which can significantly reduce the volume and weight of cores. Therefore, it is more compatible with the development trend of miniaturization and lightweight of electronic products.

Typical applications are as below:

• Common Mode Choke Cores (CMC Cores)

Nanocrystalline common mode choke core has excellent frequency and impedance characteristics, which makes it the state-of-the-art material for a wide range of applications, e.g. power supply, electric drive and electric control systems for electric vehicles, photovoltaic power inverters, wind power converters, switching power supply for home appliances, as well as EMC solutions of industrial power supplies such as inverter welding machine.

• High Frequency Power Transformer Cores (HFPT Cores)

Nanocrystalline Power transformer cores are widely used in various high-frequency industrial power supplies. For example, nanocrystalline toroidal cores are mainly used in inverter welding machine power supply, induction heating equipment power supply, communication power supply, UPS power supply, X-ray machine power supply, laser power supply, variable-frequency power supply, etc. As for nanocrystalline rectangular and C-shape cores, they are mainly used in electric locomotive traction/auxiliary power supplies, DC converters, electrostatic precipitating power supplies, etc.

• Current Transformer Cores (CT Cores)

Nanocrystalline current transformer cores are mainly used in electric power transmission, electronic watt hour meters, and leakage protection switches, etc.

Gamma rays can cause serious damage to the human body. Therefore, it is very important to develop gamma-ray shielding materials with excellent radiation shielding properties. To reach this goal, scientists in China invented a lightweight perovskite/epoxy composite that can effectively attenuate gamma rays by regulating its crystal plane. The technique will open new avenues for the effective mitigation of radiation risks in the aerospace and nuclear industries.Get more news about Shielding material,you can vist our website!

As a result of the rapid development of aerospace and nuclear industries, higher requirements are needed for the service life of detectors and the safety of staff. Gamma rays with extremely short wavelengths and strong penetration would cause serious damage to the detectors and staff. Therefore, gamma ray shielding materials with outstanding radiation shielding performance are essential.

However, the traditional lead shielding material is not suitable for further commercial applications due to its heavy weight and high toxicity. So, alternative lightweight materials with excellent radiation shielding performance that alleviate the radiation risks and reduce the costs have to be found.

In a new paper published in Light: Advanced Manufacturing, a team of scientists, led by Professor Xiaohong Wu from School of Chemistry and Chemical Engineering, Harbin Institute of Technology, China, and co-workers have developed a lightweight MAPbI3/epoxy composite prepared via a crystal plane engineering strategy.

These composites delivered excellent radiation shielding performance against gamma rays that were 10 times higher than the epoxy. MAPbI3 with altered crystal planes plays a determining role in the gamma-ray shielding performance of the corresponding composites.

Crystal plane engineering was shown to be an effective strategy to regulate the electron density of MAPbI3/epoxy composites, thereby controlling the possibility of collision between the incident gamma rays and MAPbI3/epoxy composites. The reported method and technique will open new avenues for designing and developing high-efficiency radiation shielding materials.

These scientists summarize the mechanism whereby crystal plane engineering regulates the gamma-ray shielding performance of MAPbI3/epoxy composites:

"When gamma rays (59.5 keV) reach the MAPbI3/epoxy composites, interaction between the incident gamma ray and the (110) plane or (220) plane induces the photoelectric effect. The electron density of the (110) plane is higher than that of the (220) plane.
