Abstract
Notions on the fine structure of crystals and study of processes associated with structural changes repre� sent the main concern in condensedmatter physics. They are closely related to analysis of structural rear� rangement, formation of new types of defects, phase transitions, and properties. As is known, the group of alkali feldspars (AFsp) comprises potassium and sodium feldspars (Fsp) and their intergrowths, called perthites. The potassium and sodium feldspars occur in several varieties and crystallize in different structural forms depending on the conditions. Potassium feldspars include mono� clinic sanidine, orthoclase, and adularia, and triclinic microcline. Sodium feldspars are represented by two morphological varieties: significantly more abundant
