Description. Quartz powder (with quartz sand), also known as silica is a hard, wearresistant, chemical stability of minerals, the main mineral component is quartz, the main chemical ingredient is SiO2, the color of the powder is white or colorless,
Crystalline silica (quartz) is the form of silica that OSHA is writing the new regulations to cover, it is a health hazard. It is not reactive with Portland cement meaning it does not cause ASR (Alkali Silica Reactivity) regardless of particle size. Lots of countertop makers use 30 to 40 mesh crystalline silica sand in their GFRC mixes.

Micron silica is a grade name of silica series, manufactured by 20 microns limited. Micronsil is high purity natural crystalline silica. This micronized ground silica is inherently bright, white, low in moisture inert by nature and the hardness of silica mineral yields improved burnish resistance and durability.
Its high strength and low porosity are obtained by optimizing particle packing and reducing water content. The mixture contains no coarse aggregates. Instead fine powders, such as sand, crushed quartz, and silica fume, with particle sizes ranging from to 300 |nm are used. The grain size distribution is optimized to increase the matrix density.
