Preparation and ferroelectric characterization of calcium

The prepared samples were characterized by xrd and sem techniques grain sizes and lattice parameters were calculated by sem and x-ray diffraction the final physical and electromechanical properties of ferroelectric material components greatly depend upon the preparation method used. Preparation of both neat and agnps-loaded calcium alginate beads firstly, the optimal condition for producing calcium alginate beads was carried out by electrospraying method (fig 1 ) the concentration of sodium alginate solution was 05, 10, and 15% w / v , and the applied voltage was 8, 10, 12, and 15 kv. To verify this hypothesis, we formed a hybrid calcium phosphate/chitosan coating through electrodeposition we found that the incorporation of chitosan influenced calcium phosphate formation and crystallization.
