Effect of Stabilizer on Morphology and Stability of Hemihydrate Calcium Sulfate Whiskers
The influence of stabilizer on the crystal shape and stability of hemihydrate calcium sulfate whiskers was investigated in detail. Morphology, surface group and phase composition of stabilized hemihydrate calcium sulfate whiskers were characterized by means of SEM, FTIR and XRD, and then effect mechanism was discussed. The results showed that the absorption state of sodium oleate will be different with respectively additive amount which cause whiskers shape and stability to change, and that the stability of hemihydrate calcium sulfate whiskers can be achieved without affecting crystal growth by adding agents in different steps.
