SiO2pohjaisia

SiO2pohjaisia is a Finnish term that translates to "SiO2-based" or "silica-based." It refers to materials whose primary component is silicon dioxide (SiO2), also known as silica. Silica is a naturally occurring compound found abundantly in the Earth's crust, commonly in the form of quartz. It is a highly versatile material with a wide range of applications due to its unique chemical and physical properties, such as its hardness, inertness, and thermal stability.

SiO2pohjaisia materials encompass a broad spectrum of substances. This includes naturally occurring silica minerals like quartz, sand, and diatomaceous earth. It also includes manufactured silica products such as glass, which is primarily made from silica sand, soda ash, and limestone. Fused silica, also known as fused quartz, is another important SiO2pohjaisia material produced by melting high-purity silica. Furthermore, precipitated silica and fumed silica are synthetically produced forms of amorphous silica used as fillers, thickeners, and anti-caking agents in various industries. The term can also extend to silicones, which are polymers containing silicon-oxygen backbones, often with organic side groups, and thus are considered related to SiO2.

The applications of SiO2pohjaisia materials are extensive. They are fundamental to the construction industry (e.g., concrete, mortar), the glass manufacturing sector, and the electronics industry (e.g., semiconductors). They are also used in ceramics, refractories, abrasives, filtration, and as food additives and in personal care products. The specific properties of the SiO2pohjaisia material determine its suitability for a particular application.
