onorganische

Onorganische is a term used in several Germanic languages, notably Dutch, to denote materials, compounds or chemistry that are not classified as organic. In a chemical context it commonly refers to inorganic substances: those that typically do not contain carbon–hydrogen bonds. The term appears in phrases such as onorganische chemie (inorganic chemistry).

Inorganic compounds include salts, metals, oxides, sulfides, minerals, coordination complexes and many simple carbon-containing species treated as inorganic (for example carbonates, carbides, cyanides, carbon monoxide and carbon dioxide). They exhibit a wide range of bonding types, including ionic, covalent and metallic bonds, and display diverse physical properties such as crystallinity, electrical conductivity and variable solubility.

The study of onorganische materialen encompasses synthesis, structural characterization and investigation of reactivity. Common analytical methods include X-ray crystallography, various spectroscopies (IR, Raman, NMR for certain nuclei, UV–Vis), electron microscopy and electrochemical techniques. Research spans fundamental topics in bonding and electronic structure as well as applied areas.

Applications of inorganic materials are broad: catalysts, electronic and magnetic materials, pigments, ceramics, fertilizers, corrosion inhibitors and construction materials. Inorganic chemistry also underpins mineralogy, geochemistry and materials science.

Etymologically the distinction between organic and inorganic has evolved from historical classifications; modern chemistry recognizes many overlaps and exceptions. The adjective onorganische remains in contemporary use where the inorganic character of substances or disciplines is being emphasized.
