Description
Barium Ferrite (BaFe₁₂O₁₉) Micron Powder
Purity: 99.9+%
Particle Size: 1–3 µm
Product Description
Barium Ferrite (BaFe₁₂O₁₉) is a hard magnetic material known for its strong magnetocrystalline anisotropy, high coercivity, and good chemical stability. Belonging to the hexaferrite family, BaFe₁₂O₁₉ is widely utilized in both industrial and electromagnetic applications due to its unique ferrimagnetic properties and high saturation magnetization.
With a density of approximately 5.4 g/cm³, this compound is composed of barium (Ba), iron (Fe), and oxygen (O), elements from groups S, D, and P of the periodic table, respectively. The powder form—sized between 1–3 microns—offers excellent surface area and reactivity, which enhances its performance in catalytic and composite material applications.
