Study on Chemical Types, Structural Characteristics and Classification System of Talc
Talc is a typical natural layered hydrous magnesium silicate mineral. As a core variety of non‑metallic mineral resources, it is widely applied in coatings, plastics, ceramics, cosmetics, new materials and many other fields owing to its unique chemical structure and stable physicochemical properties. The chemical type of talc directly determines its purity, whiteness, stability, processing performance and industrial application scenarios. The chemical classification, structural differences and compositional characteristics of talc constitute the fundamental basis for ore selection, quality inspection and deep‑processing applications.
