Silica Sand is a high-purity natural sand primarily composed of silicon dioxide (SiOâ??). It is formed through the weathering and erosion of quartz-rich rocks and is processed into different grades based on purity, grain size, and industrial requirements.
Silicon Dioxide (SiOâ??) 95%â??99.9%
Iron Oxide (Feâ??Oâ??) 0.01%â??0.5%
Aluminium Oxide (Alâ??Oâ??) 0.1%â??2%
Moisture Maximum 5%
Grain Size 0.1 mm â?? 5 mm
Colour White / Off-white / Transparent
Bulk Density 1.4â??1.7 g/cm³
Shape Rounded / Angular grains
Talcum powder is a soft, white powder developed from talc, or magnesium silicate, a mineral composed primarily of magnesium, silicon and oxygen. When it is finely ground, talc absorbs moisture and helps reduce friction.
