Silica flour is a fine powder of silicon dioxide (SiO\u2082)<\/a>, obtained by grinding high-purity silica sand<\/a>. Its AFS fineness index is at least 200. It is used in foundry work, epoxy concretes, ceramics and industrial coatings. Its true density of 2,650 kg\/m\u00b3 makes it a high-performance technical filler. It must only be handled by trained professionals.<\/p>\n\n\n\n

What is silica flour?<\/h2>\n\n\n\n

Silica flour is a powder of silicon dioxide (SiO\u2082)<\/a><\/strong> produced by finely grinding silica sand or natural quartz. White, odourless and chemically inert, it differs from ordinary sand in its very fine grain size.<\/p>\n\n\n\n

This is why SiO\u2082 is one of the most abundant minerals in the Earth\u2019s crust. Furthermore, this intensive grinding process transforms a raw material into a product with precise industrial specifications.<\/p>\n\n\n\n

His industrial applications<\/strong> cover several key sectors:<\/p>\n\n\n\n
