High-Purity Processed Quartz & Silica Powder
- Arihant Micron is a leading manufacturer and exporter of micronized quartz powder and silica flour, processed from selected high-purity semi-glassy and snow-white quartz lumps at our Chittorgarh plant.
- Our modern pulverizing facility utilizes high-alumina lined ball mills, micro-cyclone air classifiers, and magnetic separators to produce iron-free silica powder with consistent particle size distribution and whiteness indices up to 96%+.
- Widely utilized as a primary body filler and functional extender in artificial engineered quartz slabs, premium emulsion paints, ceramics, epoxy casting, thermal insulation, and welding electrode flux.
