Microscopic Description

Low Magnification - Well rounded crystalline discs. Small proportion agglomerate.

High Magnification (2000)- All shapes, finely divided quartz containing many minute cracks and fissures.

Characteristics

1. Rheologically superior.
2. Low oil adsorption
3. Defloculated dispersion in applied systems.
4. Unsurpassed electrical insulation properties.
5. Low abrasive coefficient compared to
other naturally occurring silicas.
6. Highly reactive silanol surface.

7. Purity.
8. Chemically inert.
9. Low long-term water pick up.
10. Anhydrous.
11. Receptive to ambifunctional siliane.
12. No ionic contamination.
