Product Parameters

Product Features

Nano ferroferric oxide powder is prepared using the aerosol ablation method, featuring high purity, small particle size, uniform distribution, large specific surface area, clean surface, no residual impurities, low bulk density, and ease of dispersion. It possesses certain magnetic properties and can undergo directional movement under an external magnetic field. Within a specific particle size range, it exhibits superparamagnetism and generates heat under an applied alternating electromagnetic field. Its chemical stability makes it highly versatile for a wide range of applications. The fine-particle nano ferroferric oxide powder produced by our company maintains the magnetic particle size at the nanometer scale. Magnetic performance tests confirm that the magnetic particles exhibit superparamagnetism, with technical indicators meeting or exceeding the performance of domestic and international magnetic nano ferroferric oxide. This provides a foundation for the application of various magnetic fluids in China.
