Silica, or silicon dioxide, is a naturally occurring silicon oxide that has the chemical formula SiO2. It’s commonly found in substances such as quartz, as well as other living organisms. In certain parts of the world, silica is abundant in sand and is a raw material for ceramics, pottery, and earthenware. As one of the most complex groupings of materials, silica can exist as a compound of several natural minerals or as a synthetic invention. Silicate minerals are some of the most ubiquitous substances in the world, found in mica, quartz, feldspar, and pyroxene. Its applications are abundant, from structural engineering to food and pharmaceuticals.
Because of its cost effectiveness, silica is used as an “extender” in many paint products. This means it acts as a filler substance and can also flatten the paint. In paints used for architectural purposes, silica provides durability and resistance against exterior factors likes dirt and weathering. In addition, silica can increase brightness and dimensionality of paints that are used for wide scale purposes.
Silica is a flexible compound that serves a range of uses across several industries. One of the most widespread uses for silicon dioxide is in the construction industry. Silica-laden sand is often used in sandcasting. It’s an ideal match for structural purposes because of its comparatively high melting point.
