Among other applications, magnesium hydroxide is commonly used as a flame-retardant filler in composite materials, as well as a precursor for magnesium oxide refractory ceramic. The microstructure of the powder is of prime importance in both technical applications. The influence of synthesis parameters on the morphological characteristics of magnesium hydroxide nanoparticles precipitated in dil...

Magnesium matrix composites are very attractive materials for various applications of aerospace, defence organizations and automotive industry due to their low density, good mechanical and physical properties. The improvement of specific strength, stiffness, damping behaviour, wear behaviour, creep and fatigue properties are significantly influenced by the addition of reinforcing elements into ...

The mechanisms of formation of biogenic magnesium-rich calcite remain an enigma. Here we present ultrastructural and compositional details of ossicles from the seastar Pisaster giganteus (Echinodermata, Asteroidea). Powder X-ray diffraction, infrared spectroscopy and elemental analyses confirm that the ossicles are composed of magnesium-rich calcite, whilst also containing about 0.01 % (w/w) of...

Magnesium oxychloride cement (MOC) foam concrete (MOCFC) is an air-hardening cementing material formed by mixing magnesium chloride solution (MgCl2) and light-burned magnesia (i.e., active MgO). In application, adding caustic dolomite powder into magnesite can reduce the MOCFC production cost. The brine content of MOC changes with incorporation powder. This study investigated relationship betwe...

Cathodic electrodeposition (CED) was used to coat the cast magnesium alloy Mg-9Al-1Zn-xRE with aluminum powder and epoxy. Immersion salt spray tests (ASTM B117) at room temperature for a total of 240 hours have been performed assess corrosion performances AZ91D alloy. At each 24-hour interval, samples were checked any damage or deterioration coating surface morphology. The X-ray diffraction (XR...

Mechanochemical methods offer unprecedented academic and industrial opportunities for solvent-free synthesis of novel materials. The need to study mechanochemical mechanisms is growing, and has led to the development of real-time in situ X-ray powder diffraction techniques (RI-XRPD). However, despite the power of RI-XRPD methods, there remain immense challenges. In the present contribution, man...

Much attention has been focused on the biomedical applications of magnesium phosphate cement (MPC) as bone substitution material. The use of porous scaffolds with characteristics such as high porosity along with macropores and three-dimensional interconnected pore structures is beneficial for repairing bone defects. MPC has been proven to be degradable and biocompatible, and therefore might be ...

  Magnesium and its alloys are light, biodegradable, biocompatible metals that have promising applications as biomaterials. Magnesium is potentially useful for orthopedic and cardiovascular applications. However, the corrosion rate of this metal is so high that its degradation occurs before the end of the healing process. One of the ways to improve the corrosion rate is to compose it’s with cer...
