Crystn. of barium carbonate from alk. silica solns. results in the formation of extraordinary micron-scale architectures exhibiting non-crystallog. curved shapes, such as helical filaments and worm-like braids. These so-called "silica biomorphs" consist of a textured assembly of uniform elongated witherite nanocrystallites, which is occasionally sheathed by a skin of amorphous silica. Although ...
