The 0.0-75 refers to the particle size distribution of the sand, with 0.0 indicating that there are no particles smaller than 75 microns in size. This type of silica sand is typically used for industrial and commercial purposes, such as in the manufacturing of glass, foundry molds, and as a filler in paints and rubber. It can also be used in construction, for example in making concrete or as a bedding material for underground pipelines.
Silica sand with a particle size distribution of 0.0-1000 would contain no particles smaller than 1000 microns (1 millimeter) in size. This type of silica sand would likely be used for construction and industrial applications where a coarser, larger particle size is needed. Some examples of use cases would be as a bedding material for underground pipelines, as a filter medium in water treatment, as a raw material for the production of glass, ceramics, and even white cement. This type of silica sand is also used as a abrasive material and in the oil and gas industry for hydraulic fracturing (fracking). However, the specific application and end use would depend on the quality of the silica sand in terms of chemical and physical properties.
