Synthesis of calcium carbide-derived carbon by mechanochemical reaction of calcium carbide with sulfur, iron sulfide and zinc oxide

In the present work, we report a novel design and preparation for the mechanochemical synthesis of calcium carbide-derived carbon (CaC2-CDC) at ambient temperature. Thermodynamic calculations confirmed the possibility of calcium carbide-derived carbon formation by the reaction of calcium carbide with sulfur, iron sulfide and zinc oxide at ambient temperature. The CDCs were synthesized by the ba...

The title compounds are formed by reaction of DyI3, Dy metal and C in stoichiometric amounts in closed Ta ampoules, Dy10(C2)2I18 at 930 ◦C for 7 days, Dy4(C2)I6 at 950 ◦C for 6 days and Dy12(C2)3I17 at 900 ◦C for 11 days as pure samples according to X-ray powder diffraction. Dy10(C2)2I18 crystallizes in space group P21/c with a = 10.470(2), b = 17.152(3), c = 13.983(3) Å and β = 121.14(3)◦ , Dy...

Crystal chemistry of layered carbide, Ti3(Si0.43Ge0.57)C2

The crystal structure of a layered ternary carbide, Ti3(Si0.43Ge0.57)C2, was studied with single-crystal X-ray diffraction. The compound has a hexagonal symmetry with space group P63/mmc and unit-cell parameters a 1⁄4 3.0823(1) Å, c 1⁄4 17.7702(6) Å, and V 1⁄4 146.21(1) Å. The Si and Ge atoms in the structure occupy the same crystallographic site surrounded by six Ti atoms at an average distanc...
