Magnesium hydroxide nanoparticles with controlled morphologies via wet coprecipitation

Synthesis and morpho-structural characterization of nanostructured magnesium hydroxide obtained by a hydrothermal method

“…3e). This increasing trend of the particle sizes with the increase in temperature was observed by Chen et al [39]; in addition, the SAED patterns also showed differences. An important improvement in the crystallinity was clearly seen in the Mg(OH) 2 nanostructures obtained at 180 1C as can be seen in the SAED pattern obtained for sample III (Fig.…”

“…Moreover, the strong and sharp diffraction peaks suggested that the Mg(OH) 2 nanoparticles were highly crystallized, which was consistent with the TEM results. It was also possible to detect a significant increase of the crystallinity degree and a faster crystal growth in the samples obtained at 180 1C which reveals that the crystallization of the brucite nanoparticles could be improved at higher temperatures [19,39]. The Mg(OH) 2 crystallite size could be estimated from XRD patterns using the Scherrer's formula.…”

A novel preparation of nanosized hexagonal Mg(OH)2 as a flame retardant

“…However, Mg(OH) 2 particles prepared by traditional methods are not suitable for use as flame retardants because their granularity, agglomeration, and morphology can seriously affect their flame-retardant properties when they are loaded into a matrix. Mg(OH) 2 nanocrystals can be synthesized with three different shapes, i.e., needle-, lamellar-, and rod-like morphologies (Chen, Zhu, Zhang, Xu, & Chen, 2008;Ding et al, 2001;Lv, Qiu, & Qu, 2004;Qiu, Xie, Ding, & Qu, 2003). Furthermore, it has been reported that if Mg(OH) 2 crystals tend to grow in the (1 0 1) polar plane during the crystallization (Jin et al, 2008;Wu et al, 2008), they will show high surface polarity and tolerate large levels of internal stress.…”

Efficient La–Ba–MgO Supported Ru Catalysts for Ammonia Synthesis

“…during the magnesium hydroxide crystallizing under the conditions of herein experiment. As a result, the magnesium hydroxide and lanthanides hydroxide will growth separately with their own nuclear and unlikely to form solid solution [10]. The crystallite sizes of BaCO 3 were derived from XRD peaks and Scherrer equation, all parameters involve in Scherrer equation and according calculated results are listed in Table 1.…”
