Iron and Nickel Cellular Structures by Sintering of 3D-Printed Oxide or Metallic Particle Inks
Inks comprised of metallic Fe or Ni powders, an elastomeric binder, and graded volatility solvents are 3D-printed via syringe extrusion and sintered to form metallic cellular structures. Similar structures are created from Fe2O3 and NiO particle-based inks, with an additional hydrogen reduction step before sintering. All sintered structures exhibit 92–98% relative density within their struts, w...
متن کاملColossal positive and negative thermal expansion in the framework material Ag3[Co(CN)6].
We show that silver(I) hexacyanocobaltate(III), Ag3[Co(CN)6], exhibits positive and negative thermal expansion an order of magnitude greater than that seen in other crystalline materials. This framework material expands along one set of directions at a rate comparable to the most weakly bound solids known. By flexing like lattice fencing, the framework couples this to a contraction along a perp...
متن کاملSolid state sintering of very low and negative thermal expansion ceramics by Spark Plasma
Lithium aluminosilicate powder precursors of compositions Li2O:Al2O3:SiO2 as 1:1:2; and 1:1:3.11 were synthesized and sintered by the Spark Plasma Sintering technique. The sintering conditions were adjusted to obtain dense ceramic materials in an attempt to avoid the presence of a glassy phase. XRD and SEM images were employed for composition and microstructure characterization. The coefficient...
متن کاملNickel Oxide (NiO) nanoparticles prepared by solid-state thermal decomposition of Nickel (II) schiff base precursor
In this paper, plate-like NiO nanoparticles were prepared by one-pot solid-state thermal decomposition of nickel (II) Schiff base complex as new precursor. First, the nickel (II) Schiff base precursor was prepared by solid-state grinding using nickel (II) nitrate hexahydrate, Ni(NO3)2∙6H2O, and the Schiff base ligand N,N′-bis-(salicylidene) benzene-1,4-diamine) for 30 min without using any solv...
