Zinc hydroxide carbonate was prepared by aging diluted zinc salt solution in presence of urea at 90ºC. Samples were identified by X-ray powder diffractograms showing the characteristic patterns of hydrozincite. The crystallinity was correlated with the concentrations of reagents. Spherulitic-type aggregates and single acicular particles were obtained from diluted chloride and nitrate solutions while porous aggregates of uniform size were formed from solutions with high chloride and urea concentrations.627-631porzinc hydroxide carbonatehomogeneous precipitationmorphologyspherulitesArtigo10.1590/S0100-40422000000500011S0100-40422000000500011Acesso abertoS0100-40422000000500011.pdf540886437584129242848093425462877182671143702858
