Glass beads are spherical particles made from high-purity glass materials, typically produced by melting, forming, and sieving soda-lime or borosilicate glass. With diameters ranging from micrometers to millimeters, they feature smooth surfaces and exhibit high transparency, excellent chemical stability, moderate hardness (Mohs 5-6), and corrosion resistance. Based on applications, glass beads are categorized into solid and hollow types.

Key applications include:

• Sandblasting & Polishing: Surface cleaning and matte finishing for metals and plastics
• Road Reflectivity: As reflective markers in road signs to enhance nighttime visibility
• Filler Materials: Functional additives in cosmetics, coatings, and plastics
• Precision Instruments: Used as measuring media in flow meters and level gauges

Due to their versatility and cost-effectiveness, glass beads are widely used in automotive, construction, chemical, and consumer goods industries, serving as an essential industrial material.
