Table shows most of the characterization techniques used in the literature. It summarized the common techniques that are widely used. We have to admit that there are an unlimited number of analytical techniques. Thus, a short list of the important techniques is included in this review (Table ). These sections will cover the techniques used for the characterization of the material's composition, phase, purity, structure, particle size and morphology, and porosity. The materials characterization should include qualitative and quantitative analysis.
