Magnetic Powder > Fe3O4 Fine magnetic powder
Fe3O4 Fine magnetic powder
Superfine iron oxide magnetic powder because of the characteristics of the magnetic material and a colorant, is mainly used to prepare a copier, laser printer using a single-component magnetic toner and magnetic ink. In this field of application of iron oxide magnetic powder particle size, hue, particle size distribution, magnetic properties and other aspects of the high demand. The Beijing North Mine magnetoelectric material development and production of its own superfine iron oxide products to meet different types of copiers, laser printers use toner requirements.
