kiselholdige

Kiselholdige refers to materials or substances that contain silicon. Silicon is a chemical element with the symbol Si and atomic number 14. It is a metalloid, meaning it has properties intermediate between those of metals and nonmetals. Silicon is the second most abundant element in Earth's crust, making up about 28% by mass. It is not found in its elemental form in nature but exists primarily as silicon dioxide (silica) and silicates.

Kiselholdige materials are diverse and widely utilized. Silicon dioxide, for example, is the main component of sand and quartz and is crucial in the manufacturing of glass, ceramics, and cement. Silicates, which are compounds containing silicon and oxygen, along with other elements like aluminum, iron, magnesium, and potassium, form the vast majority of rocks and minerals in the Earth's crust. Examples include feldspar, mica, and olivine.

In modern technology, kiselholdige materials are indispensable. High-purity silicon is the foundation of the semiconductor industry, used to create microchips, transistors, and solar cells. These components are essential for virtually all electronic devices. Silicones, a class of synthetic polymers containing silicon, are also considered kiselholdige and are known for their stability, flexibility, and resistance to heat and chemicals, finding applications in sealants, adhesives, lubricants, and medical implants. The term "kiselholdige" broadly encompasses any material where silicon plays a significant structural or functional role.
