“…This produced a denser ceramic structure and consequently, the porosity decreased. Caiyun Jia et al [19] also showed that as the sintering temperature increased from 900 to 1600 °C, the porosity of the foam alumina decreased from 82.47% to 74.92%, due to an increase in the grain size. This permitted the grains to be merged and assembled, thus reducing the open porosity.…”

Porous γ-alumina is widely used as a catalyst carrier due to its chemical properties. These properties are strongly correlated with the physical properties of the material, such as porosity, density, shrinkage, and surface area. This study presents a technique that is less time consuming than other techniques to predict the values of the above-mentioned physical properties of porous γ-alumina via an artificial neural network (ANN) numerical model. The experimental data that was implemented was determined based on 30 samples that varied in terms of sintering temperature, yeast concentration, and socking time. Of the 30 experimental samples, 25 samples were used for training purposes, while the other five samples were used for the execution of the experimental procedure. The results showed that the prediction and experimental data were in good agreement, and it was concluded that the proposed model is proficient at providing high accuracy estimation data derived from any complex analytical equation.
