Abstract

The concept of polymeric nanoheteromorphous structure PNS (structural variations at the nanometric level) of noncrystalline substance divides the materials into vitreous and ultradispersible not vitreous substance. In the case of individual chemical substance (element, chemical compound) a special case of the PNS concept is applied. It is important The representation of individual noncrystalline substance (NS) as copolymer nanofragments (dispersed to a greater or lesser extent) is important. They do not exhibit translation symmetry (long-range order), and are characterized by short-range and intermediate order of a given polymorphic modification (PM). The polymorphoid copolymerisation is a necessary and sufficient condition of formation of the noncrystalline state. The noncrystalline carbon can be regarded as dispersed polymorphoids of various carbon forms, characterized by sp3-hybridization of a chemical bond (diamond bonds), sp2-hybridization (graphite bonds), sp-hybridization (carbine structure). The noncrystalline carbon (n-С), as well as others non-crystalline materials, differ in the concentration of polymorphoids, determining the structure and properties of a noncrystalline carbon..
