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.
