Quartz use in Electrode Industry

In the electrode industry, silica sand or quartz powder is employed as one of the ingredients of a welding flux mixture. The silica minerals used for this purpose should have a composition of 97.5 to 99.5% SiO2, 0.05% (maximum) Fe2O3, and 0.03% (maximum) S, with a mesh size of +100 to 200.

Quartz Specifications

• High content of SiO2 98.5%- 99.8% . (Depending upon the grades)
• Fe2O3: 0.04% and below 0.002 %
• Mesh Size: 200 mesh, 300 mesh, 325 mesh
