摘要：

Porous hydromagnesite with rosette-like morphologies has been synthesized at 100 degreesC by a convenient hydrothermal method with the absence of additives or organic surfactants. The hydromagnesite particles are spherical with a diameter of about 250 mum. The thermal behavior of the product has been investigated by TGA-DTA technique, whilst the decomposition mechanism was confirmed by in situ high temperature X-ray diffraction analysis. The as-prepared hydromagnesite was found to have a photoluminescent emission at about 448 nm. (C) 2003 Elsevier Science Ltd. All rights reserved.
