Contact the supplier4.5.4 Powder X-ray Diffraction Powder X-ray diffraction (PXRD) data were collected using a Rigaku MiniFlex benchtop X-ray diffractometer with Cu Kα 1 radiation (λ = 1.5406 Å, 600 W, 30 kV, 15 mA) (Figure 4.6). All samples were mounted on a sample holder by dropping crystals and then leveling the sample surface with a spatula.
Contact the supplierAcid washing of Mo was avoided due to a reaction which causes the surface to oxidize. After cleaning, the elements were re weighed, and t hen arranged in the arc melter. Fine Nb flakes were placed in the bottom of the cavity, then Ti would be plac ed on top followed by the rest of the elements.

Contact the supplierOct 30, 2000·By washing the precipitate excessively with methanol, the surfactant could be removed yielding typically about 50-60 mg of a brown insoluble powder after drying. This powder still contained about 10% of volatile compounds as indicated by thermal gravimetric analysis between 300 K and 1100 K in an O2 atmosphere.
Contact the supplierIn order for NaCl to be soluble, the Na + and Cl-ions must break free from the crystal-lattice structure of the solid. When the ions are in solution, they are surrounded by water molecules, and the ions are said to be solvated, or dissolved in an aqueous solution, denoted (aq).Hence, the process of dissolving a NaCl crystal can be described by the following chemical equation (Equation 1):
Contact the supplierDissolving lithium chloride and aluminium chloride in boiling para- or meta-xylene and keeping the colourless solution at room temperature led to crystal growth of a new modification of lithium tetrachloridoaluminate, LiAlCl4, which represents a second modification (oP12, Pmn21) of the ternary salt besides the long known monoclinic form [LiAlCl4(mP24, P21/c); Mairesse et al. (1977).
