Effect of Particle Morphology on Physical, Mechanical and Wear Properties of Cobalt Metal Powders
(Springer India, 2021)
Cobalt is used in applications that require high densities and good mechanical properties. Cobalt powder is used in batteries, cemented carbides, stainless steel, machine tools and also in manufacturing of metal matrix ...
Fabrication and characterization of Yb-doped Y2O3 powders and thin films
(Carl Hanser Verlag, 2020)
Yttrium oxide (Y2O3) and ytterbium (Yb)-doped Y2O3 particles were synthesized via the sol-gel method from the aqueous solution of their nitrate salts. The synthesized powders were then deposited on Corning glass substrates ...
Formation of alpha/beta-Si(3)N(4 )nanoparticles by carbothermal reduction and nitridation of geopolymers
(Wiley, 2019)
Silicon nitride (Si3N4) particles with various alpha/beta-Si(3)N(4 )ratios were fabricated from geopolymer (GP)-carbon compositions (M2O center dot Al2O3 center dot 4.5SiO(2)center dot 12H(2)O+18C), where M is an alkali ...
Single step calciothermic synthesis of nickel boride particles in molten salt
(Springer, 2023)
Abstract
In this study, production of nickel boride (NixB) via calciothermic reduction in molten salt has been studied. Firstly, the electrochemical behaviors of CaO and NiO in CaCl2 melt were examined by cyclic voltammetry ...
The removal of heavy metals from refinery effluents by sulfide precipitation
(BERG FAC TECHNICAL UNIV KOSICE, 2023)
This study investigated the selective precipitation of copper (Cu2+), nickel (Ni2+) and zinc (Zn2+) ions from industrial wastewater by using sodium sulfide (Na2S). The effects of pH, time and free sulfide concentration on ...
