What is silica sand?

Silica sand is a granular mineral material containing a significant proportion of silica, commonly present as quartz. It becomes an industrial sand when its characteristics are selected for a defined professional use.

Terms such as industrial silica, high silica sand and siliceous sand may describe related materials, but they do not always represent the same grade.

Silica sand chemical composition

The principal component is silicon dioxide, usually present as quartz. Natural material may also contain other minerals and elements.

Industrial buyers may review:

  • silica-related composition;
  • iron and other components;
  • moisture;
  • fine-particle content;
  • colour;
  • consistency between batches.

Silica sand grades and sizes

Silica sand grades may differ by composition, preparation and particle-size distribution. Requests can involve fine products, medium fractions, coarser grains or narrow size ranges.

Silica sand sizes can influence flow, packing, filtration behaviour and processing performance.

Main silica sand uses

Common silica sand uses may include:

  • water filtration;
  • glass-related applications;
  • foundry processes;
  • construction materials;
  • mortars and technical formulations;
  • industrial floors and surfaces.

There is no single grade suitable for every market.

Preparing an enquiry

A useful request identifies the application, target particle size, volume, order frequency, packaging, destination and required documentation.
