Influence of the Process Parameters on the Formation of CaSO4·0.5H2O Whiskers

Figure 5

Influence of the molar ratios of Na2SO4 to CaCl2 on the morphology of the precursors ((a)–(c)) and the hydrothermal products ((d)–(f)). Molar ratio of Na2SO4 to CaCl2: (a), (d): 0.5 : 1, (b), (e): 1 : 1, (c), (f): 2 : 1.
