Abstract
In a bid to address environmental challenges associated with the management of waste
Coca cola glass bottle, this study sets out to develop glass ceramic materials using waste
Coca cola glass bottles. Magnesite from Sakatsimta in Adamawa state and reagent grade
chrome (coloring agent) were used to modify the composition of the coca cola glass bottle;
x-ray fluorescence (XRF), x-ray diffraction (XRD) and thermo gravimetric analysis (TGA)
were used to characterize the raw materials. Four batches GC-1= (Coca cola glass frit
+1%Cr2O3), GC-2= (97% Coca cola glass frit+ 2%magnesite+1%Cr2O3), GC-3= (95%
Coca cola glass frit+ 4%magnesite+1%Cr2O3) and GC-4= (93%Coca cola glass frit+
6%magnesite+ 1%Cr2O3) were formulated and prepared. TGA results were used as a guide
in selection of three temperatures (7000C, 7500C and 8000C) used for the study. Three
particle sizes -106+75, -75+53, -53µm and 2hrs sintering time were used. The sinter
crystallization route of glass ceramic production was adopted. Produced samples were
characterized by x-ray diffraction (XRD) technique and scanning electron microscopy
(SEM), the density, porosity, hardness and flexural strength of the resulting glass ceramics
were also measured using Archimedes principle, ASTM C373, ASTM C348, ASTM
C1327 respectively. The resulting glass ceramic materials composed mainly of
wollastonite, diopside and anorthite phases depending on composition as revealed by XRD
and SEM. The density of the samples increased with increasing sintering temperature and
decreasing particle size while the porosity was minimal and decreased with increasing
sintering temperature and decreasing particle size. The obtained glass ceramic materials
possessed appreciable hardness and flexural strength with GC-3 and GC-4 having the best combination of both properties. It is therefore recommended that both compositions be
used were a good combination of the aforementioned property is required.
