Synthesis and characterization of double phase metal nickelates/borates
Journal Title: Journal of Achievements in Materials and Manufacturing Engineering - Year 2016, Vol 76, Issue 1
Abstract
Purpose: Purpose of this research is obtaining of metal nickelates and borates as doublephase. These types of compounds display extraordinary structural diversity caused by boronand nickel which applicable in flame retardant, detergent, ceramic and such industries.Design/methodology/approach: Double phase metal nickelates and borates wereweighed in an appropriate molar ratio and homogenized in an agate mortar. The mixtureplaced into a porcelain crucible to heat in conventional high temperature furnace. Afterthe material was exposed to heat treatment at 900°C for 4 hours, and cooled down toroom temperature with many grindings. Then, final products were analyzed by powderX-ray Diffractometer (XRD) using PANanalytical X’ Pert PRO Diffractometer (XRD) withCu Kα (1.5406 Å, 45 kV and 30 mA) radiation. Fourier transform infrared spectroscopy(FTIR) was achieved on a Perkin Elmer Spectrum 100 FTIR Spectrometer from 4000 to650 cm-1. Scanning electron microscopy was achieved in SEM JEOL 6390-LV. Luminescenceproperties were performed by Andor Solis Sr 500i spectrophotometer. Conventional solidstate syntheses were done in Protherm furnace.Findings: Ni3B2O6/YBO3 and MoNiO4/Ni3B2O6 compounds as double phase wereidentified by powder XRD patterns and phase analysis of these compounds were completedby High Score Plus program. Vibrations of B-O and Ni-O bonds of functional groups weredetermined in FTIR spectrum benefiting from literature.Research limitations/implications: Implication of the synthesis method has somedisadvantages such as low homogeneity, non-uniform product etc. We tried to minimizethese negative aspects in our research and succeeded.Practical implications: Double phase Ni3B2O6/YBO3 and MoNiO4/Ni3B2O6 compoundswere synthesized by high temperature solid state synthesis route. Structural properties andphase composition analysis were realized using powder X-ray diffraction patterns.Originality/value: Value of the paper is first time conventional synthesis of double phaseNi3B2O6/YBO3 and MoNiO4/Ni3B2O6 compounds, characterization of the structures, andinvestigation of morphological and luminescent properties.
