kvartsihiekasta

Kvartsihiekka, also known as silica sand or quartz sand, is a common type of sand primarily composed of quartz crystals. Quartz is a hard, durable mineral with the chemical formula SiO2. Due to its abundance and physical properties, quartz sand is utilized in a wide range of industrial applications.

The formation of quartz sand typically occurs through the weathering and erosion of silicate-rich rocks, such as granite and sandstone. Over geological time, these rocks break down, and the resistant quartz grains are transported by wind and water, eventually accumulating in sand deposits. The purity of quartz sand can vary significantly depending on its source and the degree of contamination from other minerals. High-purity quartz sand, with very low levels of impurities like iron and alumina, is particularly valuable for specialized uses.

Key applications for quartz sand include glass manufacturing, where it is the main ingredient for most types of glass. It is also used in the production of silicon for the electronics industry, as well as in foundries for making molds and cores. Furthermore, quartz sand serves as a filtration medium for water treatment and in construction for making concrete and mortar. Its abrasive properties also lend it to use in sandblasting and as a component in sports surfaces like golf courses and baseball fields. The particle size distribution and shape of quartz sand are important factors that determine its suitability for different applications.
