Silisiumholdige

Silisiumholdige is a Norwegian adjective meaning containing silicon. It is used in chemistry and mineralogy to describe substances whose structure includes silicon atoms, often bound to oxygen or carbon.

In inorganic chemistry, silisiumholdige materials include silicon dioxide (SiO2), silicates, and silicate minerals such as quartz and feldspars. These form the framework of Earth's crust and are central to glass, ceramics, and cement production. In organic and materials chemistry, silisiumholdige compounds include silanes (Si–H or Si–C bonds) and siloxanes (Si–O–Si linkages), with silicones and other polyorganosiloxanes widely used as lubricants, sealants, cosmetics, and medical devices.

In terms of properties and uses, silisiumholdige substances range from rigid inorganic networks to flexible polymers. They underpin electronics through silicon-based semiconductors and enable specialty coatings, fibers, and construction materials. In agriculture and horticulture, silicon-containing formulations are marketed to enhance plant resilience, though silicon's essentiality varies among species.

Safety and environmental notes: crystalline silica forms can pose inhalation hazards; processing and handling require appropriate controls. Silicone-based products are generally chemically inert but may have environmental considerations related to formulation and disposal.
