“…Aluminum carbide (Al 4 C 3 ) is a nonporous crystalline material that is used in diverse applications, such as construction of carbon nanostructures, 1,2 a precursor for structured metal− organic framework growth, 3 for aluminum processing by strengthening through alloy formation, 4 and as cold electron emitters when in a one-dimensional nanowire topology. 5,6 The Al 4 C 3 crystal structure was studied previously by X-ray diffraction (XRD) 7−9 and solid-state 27 Al NMR; 10 however, we are finding differences in the measurements of the quadrupolar tensors for 27 Al by solid-state NMR, as well as detecting multiple, different impurities present that can impact both the spectroscopy and the chemical reactivity of the reagent.…”

The structure of aluminum carbide (from two different manufacturers) has been interrogated by 27 Al solid-state NMR in an effort to accurately characterize the material. Quadrupolar line shapes for 27 Al sites such as these are important to catalogue, as efforts are underway to employ NMR crystallography tools to understand and predict both solid-state structures and perturbations to these that are relevant to NMR analyses. Impurities present in both of the samples are revealed to be aluminum oxycarbides, as well as an aluminum metal impurity in one and aluminum nitride in anotherpotentially important information for groups employing aluminum carbide in syntheses or in other applications. Triple-quantum magic-angle spinning (3Q-MAS) 27 Al NMR was employed to help determine the quadrupolar parameters of the two crystallographically inequivalent aluminum sites in Al 4 C 3 . Revised values for the quadrupolar tensors of this material were measured and simulated through use of CASTEP-NMR.

“…7,10 The dispersion of fine Al 4 C 3 particles strengthens certain Al alloys 11,12 and coating Al alloy surfaces with Al 4 C 3 can enhance the wear resistance of the metal significantly. 13 Al 4 C 3 is a starting point for the growth of an array of structurally related compounds and materials, such as the diamond-derived (Al 2 O 3 -Al 4 C 3 -AlN) intergrowths. 14 Al 4 C 3 can also act as a template for designing microstructures such as nanoscale carbons.…”

The phase-pure binary aluminium carbide, Al4C3 can be synthesised in vacuo from the elements in 30 minutes via microwave heating in a multimode cavity reactor. The success of the reaction is dependent on the use of finely divided aluminium and graphite starting materials, both of which couple effectively to the microwave field. The yellow-brown powder product was characterised by powder X-ray diffraction, scanning electron microscopy / energy dispersive X-ray spectroscopy thermogravimetric-differential thermal analysis and Raman spectroscopy. Powders were composed of hexagonal single crystallites tens of microns in diameter (Rhombohedral space group R3 ̅ m; Z = 3; a = 3.33813(5) Å, c = 25.0021(4) Å) and were stable to 1000 °C in air, argon and nitrogen. Equivalent microwave reactions of the elements in air led to the formation of the oxycarbide phases Al2OC and Al4O4C.

“…Carburizing of aluminium, silicon, iron, different type of steels and others by employing different techniques has carried out to get tribologically and mechanically improved surfaces [21][22][23][24][25]. Therefore carburizing of zirconium by carbon ion implantation using plasma focus device is performed assuming that it may lead to improve the surface properties.…”
