Abstract
The aim of this study is to investigate the effects of Iraqi Porcelanite
compositions on the properties of ceramic tiles at 1200°C, and compare the Modulus
of Rupture of ceramic tiles by using experimental and simulation methods using
SolidWorks software. To achieve the first objective, ceramic tile powders with varying
compositions were milled and compacted at 28 MPa to produce rectangular samples,
then fired at 5°C/min up to 1200°C, soaked for 6 hours, and then cooled down to room
temperature. Four compositions were tested: Control (0 wt.% Iraqi Porcelanite), A (1
wt.% Iraqi Porcelanite), B (3 wt.% Iraqi Porcelanite), and C (5 wt.% Iraqi Porcelanite).
Among these, Sample B exhibited the most desirable properties: high bending strength
(45.6 MPa), high fired shrinkage (36.25%), high bulk density (2.61 g/cm3), low water
absorption (0.36%), and low apparent porosity (0.90%). The improvements in bending
strength for Sample B can be attributed to the formation of mullite and amorphous
glass phase. Conversely, Sample C displayed inferior properties due to excessive
fluxing agent content that inhibited mullite formation. For the second objective, a
three-point bending test simulation was conducted using SolidWorks to estimate the
MOR of the fired ceramic tiles. The simulation results mirrored the experimental
trends but yielded significantly lower MOR values, likely due to several assumptions
made during the simulation works. Overall, this study demonstrated the potential of
incorporating Iraqi Porcelanite into ceramic tile compositions and highlights areas for
improvement in simulation techniques to predict properties for porcelain tiles.
