Iron Oxide for Ferrite Devices
Brand: Xinhua
Chemical name: Ferrite Oxide (205 iron oxide red)
Molecular formula: Fe2O3
Molecular weight: 159.7 (international atomic weight in 1987)
Properties: It is red brown powder; apparent density 0.5-1.0g/cm3; not soluble in water; melting point 1565°C; it has high purity, even particle size, low impurity content and good dispersion; it is used to manufacture high magnetic permeability(μ), high saturation magnetic induction(Bs) and low power consumption(P) magnetic material.
Used: 205 iron oxide red is mainly used in transformers of high magnetic permeability,
high saturation magnetic induction and low power consumption for switchers, filter,
offset core, etc.
Standard: Q/X HH01-97
