Characterization of Hexaferit's Barium Composite Magnets with the addition of Feb as a matrix and silicone rubber as a filler

Introduction

In recent years, the development of magnetic materials has been a rapidly growing field, with various researchers and scientists working to create innovative materials with improved properties. One such material is the barium hexaferit-based composite magnet, which has been successfully developed with the addition of Feb as a matrix and silicone rubber as a filler. This article aims to discuss the characterization of this composite magnetic material, including its microstructure analysis, measurement of bulk density, magnetic properties, and tensile tests.

Manufacturing Process

The manufacturing process of barium hexaferit-based composite magnets begins with the milling of raw materials, including barium hexaferit and FEB, using a Planetary Ball Mill (PBM) for 24 hours. This is followed by High Energy Milling (HEM) for 1 hour to ensure a uniform mixture. The mixture is then stirred using PBM with a composition of the Bafe12O19 Ratio: Feb each of 97: 3, 95: 5, and 93: 7 %. After grinding, the mixture powder is calcined at a temperature of 900 ° C, and then added rubber silicone as a filler with a percentage of 20, 30, 40, and 50 by weight.

Characteristics and Results of Composite Magnetic Testing

The characterization of this composite magnetic material includes microstructure analysis using X-Ray Diffraction (XRD), measurement of bulk density, magnetic properties with vibrating sample magnetometer (VSM), and tensile tests. The results of XRD analysis show that the addition of Feb increases the hematite phase (Fe2O3) in material structure, indicating a significant interaction between raw materials, which can affect the magnetic properties of composite.

From the measurement results, the highest bulk density value was found in the addition of 20% of the weight of rubber silicone, which was 2,251 × 10^-3-3 kg/m³. In addition, the coercive value obtained is JHC = 2.85 × A/M, while the young modulus value measured reaches 0.99 MPa. These results indicate that the magnetic composite produced has good characteristics and is suitable for use in applications that require permanent permanent magnetic materials, because it has a high coercion.

Analysis of Magnetic Properties and Potential Application

Success in producing composite magnets opens opportunities for further application in the industry, especially in sectors that require high-performance magnetic materials. For example, in making electric motors, generators, or even in energy storage applications, this material can increase the efficiency of the device.

The existence of rubber silicon as a filler also has the potential to have a positive impact on the elasticity and physical endurance of the material, making it more flexible and resistant to mechanical damage. Therefore, in-depth characterization and understanding of the interaction between materials in this composition is very important for the development of better materials in the future.

Conclusion

In conclusion, the characterization of barium hexaferit-based composite magnets with the addition of Feb as a matrix and silicone rubber as a filler has been successfully carried out. The results of this study indicate that the magnetic composite produced has good characteristics and is suitable for use in applications that require permanent permanent magnetic materials. Further research is expected to explore variations of composition and manufacturing methods to improve the performance and durability of this barium hexafer-based composite magnet, as well as find a broader application for this innovative material.
