Abstract
A type of calcium and titanium precipitation (CTP) material was synthesized by means of a simple co-precipitation method. X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, and field emission scanning electron microscopy (FESEM) measurements were utilized to characterize the component, structure, and morphology of the CTP nanoparticles. The obtained particles were nano-scale and rod-like. The electrorheological (ER) measurement showed that the yield stress of the ER fluids reach about 146 KPa at a DC electric field of 5 KV/mm when the weight fraction is 67 wt%. It is substantially enhanced in comparison with the as-reported CTP ER fluids prepared by oxalate route. Furthermore, the ER fluids are very stable, environmentally friendly and attractive for large-scale utilization.
