New Methodology in Modeling Ceramics

Article Preview

The improvement of ceramic synthesis and processing methodology based on digital image processing and analysis of ceramic samples is in its initial stage. The main reason is that the models are based on poorly obtained data from sample’s digital image processing. The lack of a solid statistical analysis and digital-imaging setup standardization make the method less useful that it should be if set in a sound basis. Therefore the importance of setting a new methodology in digital image processing for data acquisition on ceramic morphology analysis is essential for setting new models for customized ceramic synthesis and processing. The present paper shows results based on Scanning Electron Microscopy (SEM) from Al2O3 ceramics obtained by starch consolidation method. Observation of different sample’s regions allowed a more accurate description of ceramic morphology. Plots of resistance to flexion versus porosity and its correlation with the grain size and shape allowed one to choose the best model for representing ceramic’s morphology. Correlation of starch percentage with sample’s porosity and mechanical resistance allowed the best experimental conditions for customized ceramic’s performance.
