Relationship of Structure and Colour Stone-Casting Materials Made of Mineral Aggregates and Technogenic Raw Materials

摘要

The article discusses the dependence of color stone-casting materials on the characteristics of it's structure. Proved that the main influence on color provides calcium fluoride, coloring in one or another shade of the material occurs as a result of lattice defects, which lead to a change in refractive power of the crystals in the structure of the stone-casting. Found that the main structure-forming processes in stone-casting materials with high content of calcium fluoride are the formation of heterogeneous centers of crystallization of the fluoride and liquid separation into two immiscible phases.
