Hydration Capacity

The influence of sodium citrate on the hydration capacity of hemihydrate calcium sulfate whiskers was investigated. The products were characterized by FTIR, SEM and XRD.The results show that the absorption of the sodium citrate on the surface of the hemihydrate calcium sulfate whiskers is not uniform, and the adsorption state also changed with the amount of sodium citrate. Sodium citrate plays role on the hydration capacity of hemihydrate calcium sulfate whiskers.

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.
