microsphere

Minuscule hollow particle

A microsphere is a tiny spherical particle, typically ranging from one to a thousand micrometers in diameter.

Microspheres appear across many fields: hollow glass microspheres lighten composite materials, polymer microspheres deliver drugs in controlled-release formulations, and ceramic microspheres serve as industrial abrasives.

The paint contains microspheres that reflect light.
