Lead phosphate crystals were grown in agarose gel at room temperature. Nucleation and crystal growth rates were controlled by changing the density of the gel medium including pure and phosphate gel. Individual crystallites from the pure gel layer show equant habit while those from the PO4 3− gel layer show plate-like habit. Vibrational spectra indicate that the PO4 3-ion is distorted and its symmetry is lower than free ion symmetry. Powder diffraction patterns of the pure gel products showdoi:10.4186/ej.2012.16.3.161 fatcat:rsuqenxnpzbmrbqunmx76polq4
