Influence of the Process Parameters on the Formation of CaSO4·0.5H2O Whiskers
Figure 3
Influence of the mixing ways of the reactants on the morphology of the precursors ((a)–(c)) and the hydrothermal products ((d)–(f)). Mixing of reactants: (a), (d): adding CaCl2 to Na2SO4, (b), (e): adding Na2SO4 to CaCl2, (c), (f): adding CaCl2 and Na2SO4 simultaneously to a blank container.
