Chemical Composition Analysis

<p><em>Salt is one of the most used seasoning in culinary with a great variety of them. Despite that, there is not a lot of published studies that analyses its compositions, differences and similarities between them. </em><em>Thus, this research aims to determine the inorganic composition of table, light, pink and black Himalayan, Hawaii’s red, </em><em>Persian blue, Mediterranean sea and three Argentinian gourmet salts</em><em> by the Wavelength Dispersive X-ray Fluorescence (WDXRF) method in order to compare them using </em><em>PCA and HCA analysis</em><em>. Na and Cl were major elements found in all samples. </em><em>As for trace elements:</em><em> Al, Si, S and K in drastically different concentrations, due to conservation of </em><em>nutrients from the soil, water or additives. These differences were used to distinct three groups showing that there is between 70 and 60% </em><em>similarity </em><em>among the nine samples, while </em><em>the light salt does not have similarity to any other salt studied.</em><em></em></p>

Effective Design

For refractory application, amongst others, inorganic chemical binders are used to shape and process loose, unpacked materials. The binder influences the chemical composition within the ceramic body during setting, aging and firing and thus the finally reached properties of the refractory material. For an effective design of tailored materials with required properties, the mode of action of the binder systems should carefully be investigated. A combination of both structure analysis techniques and macroscopic property investigations proved to be a powerful tool for a detailed description of structure–property correlations. This is shown on the basis of X-ray powder diffraction and nuclear magnetic resonance spectroscopy analyses combined with observation of (thermo)mechanical and chemical investigations.
