Spherical beads are small, round objects often made from materials like glass, plastic, or wood. They come in various sizes and colors, making them popular for crafts, jewelry making, and decorative purposes. Their shape allows them to roll easily, which can be useful in certain applications, such as in games or as components in machinery. These beads can also be used in scientific and industrial settings. For example, in catalysis, spherical beads can serve as catalysts to speed up chemical reactions. Additionally, in medical applications, they may be used in drug delivery systems, where their shape helps control the release of medication in the body.
