Abstract in another language
A colored platy substrate with appreciable aspect ratio can improve the hiding power while extending the color range of pearlescent pigments. One of the oldest synthetic pigments, Egyptian blue, possesses a layered structure and a platy morphology, making it a promising colored substrate for pearlescent pigments, which derives its blue color from Cu-II. Unfortunately, existing synthesis routes are either not technically benign or lack the natural platy morphology. Here, we introduce a new synthesis route starting with large, square-shaped platelets of a synthetic layered sodium silicate (NaRUB-18). As evidenced by Rietveld refinement and scanning electron microscopy, NaRUB-18 can be converted with conservation of this attractive morphology (pseudomorphosis) into Egyptian blue.
