ultrafine
Beyond merely small
Ultrafine describes particles or materials ground to an extremely small size, finer than standard grades: ultrafine powder, ultrafine mesh.
The term appears frequently in materials science, cosmetics, and air quality discussions, where ultrafine particles are small enough to penetrate deep into the lungs.
In everyday use, it often markets products as superior: ultrafine tip markers, ultrafine sugar.
