INDEXING SCHEME RELATING TO STRUCTURAL AND PHYSICAL ASPECTS OF SOLID INORGANIC COMPOUNDS
NOTE
-
This subclass constitutes an internal scheme for indexing only.

The indexing scheme is used to identify structural and physical aspects of solid inorganic compounds, already classified in class C01 or subclass C09C.
