Growth morphology of sodium fluorosilicate crystals and its analysis in base of relative growth rates

Investigation of growth kinetics and morphology of sodium fluorosilicate ice‐analogue crystals in solutions and gels

“…Theoretical analysis of relative growth rates [10] in connection with above experimental data concerning the growth of columnar and platelet crystals allowed us to determine the conditions for relative growth rates R basal /R pyram and R pyram /R prism at which the crystals of hexagonal columns and plates grow. These results are published elsewhere [11]. At moderate supersaturations crystals very frequently form twins.…”

Growth morphology of crystals from kinetic and geometric perspective

“…Sodium fluorosilicate crystals grown from solutions and gels shows habits typical for ice crystals growing in the atmosphere: hexagonal columns, hexagonal plates, stellar and sectored plates, simple star, stellar and radiating dendrites [17,19,20]. The details of experimental procedure are given in [19,20].…”

Nanoparticle-mediated nonclassical crystal growth of sodium fluorosilicate nanowires and nanoplates

“…The larger micrometer-sized Na 2 SiF 6 plates had been observed. 23 However, their nanowires and nanorods have never been observed previously. Figure 2(c) shows the TEM image of the Na 2 SiF 6 nanorods at their intermediatestage.…”

“…Generally, Na 2 SiF 6 crystals have been supposed to form through traditional ion-byion crystallization process. 23 There have been a few studies on their single crystals with sizes of over tens of micrometers, whereas there have been no reports on the fabrication and study of their nanoscale structures. Figure 1 displays the TEM images of the fabricated Na 2 SiF 4 nanoplates at their successive crystallization stages.…”
