STUDY ON PHYSICAL-CHEMICAL PROPERTIES OF FURNACE-NICKEL-SLAG POWDER FOR GEOPOLYMER APPLICATION

ABSTRACT: This research aims to prepare powder of nickel slag from furnace machine, identify, and analyze of the elements or compounds containing in the sample. The data retrieval was done with the analysis of elemental composition, phase microstructures, crystal size, distribution, and composition mapping of the samples by using XRD, Rigaku Miniflex II, and SEM-EDS, Tescan Vega-3. XRD result indicates that the formation which the similar to amorphous phase was identifed and the formation at peak 2θ = 28.01° is identifed as the low quartz (SiO2). FWHM 0.18° was obtained using microcal origin 6.0 and average crystal size 53.37 nm was obtained by applying Scherer equation. SEM results show average grain size of samples which is less than 1μm and maximum to 4μm. Based on EDS result, the main constituent elements are Si 32.86 wt%, Mg 19.40 wt%, and Fe 32.03 wt%, respectively.
