Iota 8 high purity quartz |
| Preparation: |
milled silica was cleaned by adding 10 g of each phase to a 180 mL centrifuge bottle with approximately 180 mL 0.01M NaOH. The suspension was mixed for one hour then centrifuged 60 minutes at 4500 rpm in a swing-bucket rotor (centrifuge: Allegra-22R, rotor: S4180). This left particles less than 150 nm in suspension. The NaOH supernatant was decanted and the solution was replaced with 0.01 M HNO3, mixed for 1 hour, then centrifuged as described above. The HNO3 phase was decanted and replaced with ultrapure MQ H2O. This suspension was mixed by hand for approximately 3 minutes then centrifuged, the aqueous phase decanted, and the procedure repeated 5 times. The final wet solids were transferred to a glass petri dish and dried in an oven at 105 °C. After drying, the solids were lightly ground with a mortar and pestle to break up aggregates then stored in glass vials |
