- In detail
Atomized Ferro Silicon Powder has low oxygen content, spherical particle shape, spreading and excellent fluidity characteristics. The atomized ferro silicon powder can not be matched or replaced by the common ferro silicon powder.
The atomization process ensures minimal or no hydrogen gas evolution when blended with the welding flux raw materials and binders. This ensures no cracks due to hydrogen evolution in the finished welding electrodes (Low Hydrogen electrodes). Also the spherical particle shape ensures the proper blending of atomized ferro silicon powder with the other raw materials in the welding flux. Atomized Ferro Silicon Powder is a definite raw material for those who want to make quality electrodes. Atomized Ferro Silicon Powder is undeniably better than the stabilized Ferro Silicon Powder or Untreated Ferro Silicon Powder.
Ferro silicon is used for heavy media separation and atomization. Ferro Silicon is also widely used in casting, melting and related metallurgy industry. It can be used as basic materials for adjusting, inoculation, suspending, coating and deoxidization in steel melting, casting, mineral processing and melting rod industry. It is also used for production of semiconductors, pure silicon in electric industry and silicon copper in chemistry industry.
