Solid glass balls are dense, non‑hollow spherical particles manufactured from high‑quality soda‑lime glass. They feature good sphericity, smooth surface, uniform particle size and stable chemical performance.
Key Properties
- Material: Soda‑lime glass (standard)
- True density: 2.45‑2.50 g/cm³ (soda‑lime)
- Mohs hardness: 6‑7
- Softening point: approx. 700‑750 °C for soda‑lime glass
- High roundness, low broken‑particle rate, excellent acid‑alkali resistance
