  • Pictogram(s):IrritantXi

  • Hazard Codes:Xi

  • Signal Word:No signal word.

  • Hazard Statement:none

  • First-aid measures: General adviceConsult a physician. Show this safety data sheet to the doctor in attendance.If inhaled Fresh air, rest. In case of skin contact Rinse skin with plenty of water or shower. In case of eye contact Rinse with plenty of water for several minutes (remove contact lenses if easily possible). If swallowed Rinse mouth. Absorption, Distribution and Excretion...Three mature ewes each received by intrarumenal infusion a supplement of 0, 1, 2 and 3 g Mg/d in sequence over four 10-day periods. Net Mg absorption distal to the pylorus took place down its electrochemical gradient, although the quantity absorbed remained small during the control and first infusion periods. The bulk of Mg absorption occurred before the pylorus and, during the control and first infusion periods, took place against its electrochemical gradient. The net Mg absorption proximal to the pylorus rose with declining efficiency as Mg intake was increased. It is suggested that saturation of the absorption process at this site was occurring.

  • Fire-fighting measures: Suitable extinguishing media In case of fire in the surroundings, use appropriate extinguishing media. Wear self-contained breathing apparatus for firefighting if necessary.

  • Accidental release measures: Use personal protective equipment. Avoid dust formation. Avoid breathing vapours, mist or gas. Ensure adequate ventilation. Evacuate personnel to safe areas. Avoid breathing dust. For personal protection see section 8. Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Pick up and arrange disposal. Sweep up and shovel. Keep in suitable, closed containers for disposal.

  • Handling and storage: Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Avoid exposure - obtain special instructions before use.Provide appropriate exhaust ventilation at places where dust is formed. For precautions see section 2.2. Dry.

  • Exposure controls/personal protection:Occupational Exposure limit valuesBiological limit values Handle in accordance with good industrial hygiene and safety practice. Wash hands before breaks and at the end of workday. Eye/face protection Safety glasses with side-shields conforming to EN166. Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU). Skin protection Wear impervious clothing. The type of protective equipment must be selected according to the concentration and amount of the dangerous substance at the specific workplace. Handle with gloves. Gloves must be inspected prior to use. Use proper glove removal technique(without touching glove's outer surface) to avoid skin contact with this product. Dispose of contaminated gloves after use in accordance with applicable laws and good laboratory practices. Wash and dry hands. The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the standard EN 374 derived from it.

Controlled synthesis of Mg(OH)2 nanorods using basic magnesium chloride as precursor

Chai, Shu-Jing,Luo, Bi-Jun,Wu, Hai-Hong,Wu, Dan,Lu, Shao-Yan,Zhang, Qi

, p. 90 - 101 (2021/07/07)

Mg(OH)2 nanorods were successfully prepared by two-step method. The precursor was obtained by hydrolyzed the MgCl2 in NH3·H2O solution, and then, it transformed into Mg(OH)2 nanorods by a simple solvothermal method without any surfactant or catalyst. The influences of synthesis parameters on the morphological characteristics and sizes of Mg(OH)2 nanoparticles were investigated, such as the proportion of EtOH–H2O solvent, the reaction temperature, and the treatment time. XRD and FESEM were used to characterize the structure, morphology, and composition of the samples. This method is lower costing, simple and environmentally benign, thus, it should be easy to be scaled up for industrial production.

In-situ observation on the magnesiothermic reduction of TiCl4 around 800 °C by microfocus X-ray fluoroscopy

Kishimoto, Akihiro,Uda, Tetsuya

, (2021/05/06)

In the industrial smelting process for titanium metal, liquid TiCl4 is supplied on molten magnesium and reduced to porous titanium in a closed steel or stainless steel container at 800–900 °C. In the present study, in-situ observation on the magnesiothermic reduction of TiCl4 was performed by microfocus X-ray fluoroscopy. We successfully observed that the molten magnesium creeps up on container walls rapidly and that porous titanium is mainly deposited and grows on the walls by reduction of gaseous TiCl4 by the magnesium. This unique behavior of magnesium is attributed to the capillary action of molten magnesium through pores of titanium deposited on the walls.

Ionic liquids as an efficient medium for the mechanochemical synthesis of α-AlH3 nano-composites

Duan,Hu,Ma

, p. 6309 - 6318 (2018/04/23)

Aluminum hydride (AlH3) is one of the most promising hydrogen storage materials that has a high theoretical hydrogen storage capacity (10.08 wt%) and relatively low dehydriding temperature (100-200 °C). In this work, we present a cost-effective route to synthesize the α-AlH3 nano-composite by using cheap metal hydrides and aluminum chloride as starting reagents and to achieve liquid state reactive milling. The LiH/AlCl3 and MgH2/AlCl3 reaction systems were systemically explored. The phase identification of the obtained products was carried out by XRD and the morphology observed by TEM characterization. It was found that the α-AlH3 nano-composite can be successfully synthesized by reactive milling of commercial AlCl3 and LiH in a neutral ionic liquid ([2-Eim] OAc). Based on XRD analysis and TEM observation, an average grain size of 56 nm can be obtained by the proposed mechanochemical process. By setting the isothermal dehydrogenation temperature between 80 and 160 °C, the as-synthesized α-AlH3 nano-composite exhibits an advantage in hydrogen desorption capacity and has fast dehydriding kinetics. The hydrogen desorption content of 9.93 wt% was achieved at 160 °C, which indicates the potential utilization of the prepared nanocomposite in hydrogen storage applications.
