Skivformade

Skivformade is an adjective used in Swedish to describe objects whose overall geometry approximates a disk: a circular outline when viewed from above, with a flat surface and relatively small thickness compared with the diameter. The term derives from skiva, meaning disc or plate, and formade, formed or shaped. It is used primarily as a descriptive morphology term in scientific and technical writing rather than as a distinct category.

In biology, skivformade shapes are common among small cellular fragments and cells. Platelets (thrombocytes) are typically discoid in shape and are described in Swedish literature as skivformade. Red blood cells are more accurately disc-shaped as well; in hematology the term discocyte is used internationally to denote a disc-shaped erythrocyte.

In materials science and nanotechnology, skivformade particles refer to disk-shaped or discoidal particles. Such bodies have high aspect ratios and a large surface area relative to volume, affecting packing, flow, optical, magnetic, and catalytic properties. Disk-shaped nanoparticles, nanodiscs, and thin-film disks are studied for catalysis, drug delivery, and magnetic data storage applications.

In geology and mineralogy, the term may be used for minerals or crystals that crystallize in a roughly disc-like habit, though discoid forms are more commonly described with other terms.

The term remains a practical descriptor rather than a strict classification, useful for characterizing morphology across disciplines.
