23 Synchrotron X-ray powder diffraction and infrared (IR) spectroscopy studies on 24 natural brucite were conducted up to 31 GPa using diamond anvil cell (DAC) techniques 25 at beamlines X17C and U2A of National Synchrotron Light Source (NSLS). The lattice 26 parameters and unit-cell volumes were refined in m1 3 P − space group throughout the 27 experimental pressure range. The anisotropy of la...

The structure, synthesis and magnetic properties of three new complex cobalt hydroxyl oxalates are presented, showing a modification of the 2-D double layer hydroxide structure. Co(12)(OH)(18)(ox)(3)(pip) [ox = oxalate, C(2)O(4)(2-); pip = piperazine, C(4)N(2)H(10)] (1), is essentially built from brucite-like layers with a one ninth depletion of the octahedral sites and a preservation of a trig...

A magnesium hydroxide-montmorillonite complex prepared at an OH/Mg molar ratio of 2 (16 meq Mg/g clay) and immediately cleaned of any free Mg(OH)2 behaves like magnesium-chlorite and shows no change during 3 months ageing. Magnesium hydroxide completely precipitates within the interlayer space of montmorillonite. X-ray diffraction analysis, thermal (DTA and TGA) studies, i.r. absorption analysi...

Little is known about the performance of ettringite-based binders in hydrothermal conditions. This investigation aims to gain insights into phase evolution and corresponding mechanical an binder considering crystallization pressure caused by late-reaction products. Additionally, role fiber reinforcement on strength retention was investigated. When aged at elevated temperature under water-satura...
