Glass prepared from pyrogenically prepared silicon dioxide |
| 摘要 |
Pyrogenically prepared silicon dioxide with the following physicochemical properties: 1. Average particle size (D50 value) D50>=150 nm (dynamic light scattering, 30 wt %) 2. Viscosity (5 rpm, 30 wt %)eta<=100 m.Pas 3. Thixotropy of Ti(eta(5 rpm))/(eta(50 rpm))<=2 4. BET surface area 30-60 m<2>/g 5. Compacted bulk=100-160 g/L 6. Original pH<=4.5 that can be used for the preparation of dispersions and glass bodies.
