Støtmineraler

Støtmineraler are a category of minerals that possess a specific set of physical properties that make them suitable for use in applications requiring high resistance to impact and abrasion. These properties often include exceptional hardness, toughness, and a granular or crystalline structure that can withstand repeated mechanical stress. The term "støtmineraler" is primarily used in Scandinavian languages, translating roughly to "impact minerals" or "shock minerals."

The composition of støtmineraler can vary widely, but they are typically natural, inorganic solids. Common examples include certain types of quartz, feldspar, and basalt. The specific geological formation and the presence of impurities or specific mineral phases can influence their suitability for various applications. For instance, minerals with interlocking crystal structures tend to exhibit greater toughness and thus are better suited as støtmineraler.

The primary uses of støtmineraler are in construction and industrial settings. They are frequently employed as aggregate in concrete and asphalt, where their resistance to wear and tear contributes to the durability of roads, bridges, and buildings. They are also used in the manufacturing of grinding media, such as balls or rods used in milling processes for ores and other materials. Furthermore, their abrasive qualities make them valuable in sandblasting and other surface preparation techniques. The selection of a specific støtmineral depends on the required performance characteristics of the final product or application.
