| CHEMICAL PROPERTIES OF SANDSTONE & QUARTZITE | |
| Chemically they are very resistant Mono-Mineralic rocks, principally of silica. | |
| SiO2 | 93-94% |
| Iron (Fe2O3) | 1.5%-1.6% |
| Alumina (Al2O3) | 1.4 to 1.5% |
| Soda (Na2O) & Potash (Kro) | 1.0% to 1.2% |
| Lime (CaO) | 0.8% to 0.9% |
| Magnesia (MgO) | 0.2 to 0.25% |
| Loss On Ignition (LOI) | 1.0% to 1.2%. |
| They are highly resistant to avoids, alkalis and thermal impact. Insolubility in acids and alkalis is about 97%. | |
Quartzite
Quartzite stones are extremely hard and weather resistant stones. The natural quartzite stones makes a perfect choice for wall-cladding, roofing, flooring and all other types of interior & exterior applications. Having granolithic texture, these Indian natural quartzite stones are fireproof and non-slippery in nature. We can offer natural quartzite stone in different variations including Him White and Him Black. The quartzite stones can be honed, polished and cut to the size required by the clients.
