Silica sand
Silica sand is an industrial term used for sand or easily disaggregated sandstone with a very high percentage of quartz (Silica Dioxide SiO2) grains.
Silica sand is an industrial term used for sand or easily disaggregated sandstone with a very high percentage of quartz (Silica Dioxide SiO2) grains.
Silica Sand is a naturally occurring granular material composed of finely divided rock and mineral particles. It is defined by size, being finer than gravel and coarser than silt.
The natural silica filtration grade sands have a sub-angular to rounded shape, making them an ideal filtration media to capture suspended solids in water. Due to the high silica content, the sand is extremely durable and hard-wearing, allowing it to be precisely graded to facilitate efficient filtering.
