The production method of fused quartz glass can be: electrically fused, flame fused, plasma fused and electric-arc fused. The raw material can be natural quartz sand SiO2 and synthetic chemical-silicon tetrachloride(SiCl4). The combination of production methods and raw material composes the main 6 types of our quartz glass: EN (electrically fused natural quartz) series; FN (flame fused natural quartz) series; PN (plasma fused natural quartz) series; FS (flame fused synthetic quartz) series; PS (plasma fused synthetic quartz) series; AN (electric-arc fused natural quartz) series.
