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.PAS3. Thixotropy of Ti (eta(5 rpm))/(eta(50 rpm))<=24. BET surface area 30-60 m<2>/g5. Compacted bulk=100-160 g/L6. Original pH<=4.5can be used for the preparation of dispersions and glass bodies.
