Thin silica flakes and method of making |
| abstract |
Hydrated sodium silicate particles can be nexpanded by heat to form thin-walled bubbles that can be nbroken, neutralized, washed and dried to provide hydrated nsilica flakes. These flakes (30) can be mixed with non-swelling nsorptive particles (36) such as TLC grade silica and used to nmake chromatographic articles. One such article (32) is a ncomposite of a poly(tetrafluoroethylene) fibril matrix (34) in nwhich those particles and hydrated or fired silica flakes nare enmeshed. The hydrated silica flakes can be fired to a nrefractory state and then incorporated into protective ncoatings to enhance their resistance to abrasion while also nbetter protecting the coated substrates from corrosion. |
