Product Overview

Quartz is one of the most abundant and hardest naturally occurring minerals. At Rajgarh Minerals, we process highly pure, milky white quartz lumps from the best veins in Rajasthan to produce a finely milled silica powder. With a Mohs hardness of 7, Quartz Silica Powder provides unmatched abrasion resistance. It is highly resistant to chemicals, acids, and thermal shock. It is a crucial ingredient in the glass manufacturing industry and the ceramics industry (providing the glassy phase in glazes). In paints, it provides heavy-duty abrasion resistance for floor coatings and road marking paints. In construction, it is a key aggregate and filler in high-performance epoxies, self-leveling floors, and engineered stone.

Industrial Applications

Glass & Ceramics

Essential raw material for clear glass. Provides the glassy matrix in ceramic glazes.

Paints & Coatings

Used in road marking paints, marine coatings, and floor epoxies for high abrasion resistance.

Construction Chemicals

High-strength filler in epoxy resins, grout, and self-leveling compounds.

Engineered Stone

Primary component in artificial quartz stone slabs.
