Special rules of classification within this subclass

The Physical properties of the specific compounds of metals are indexed according the C01P-Indexing Code scheme.

In case a group is indicated as indexed, the subgroups thereof are also indexed

The C01P-indexation scheme deals with Structural and Physical Aspects of Solid Inorganic Compounds classified in subclasses C01B to C01G and C09C.These aspects include crystal-structural characteristics, particle morphology and physical properties.

Exception from the last appropriate place rule :

Dopant: A dopant, also called a doping agent, is a trace impurity element that is inserted into a substance (in very low concentrations) in order to alter the physical properties of the substance. For the purpose of classification, a dopant is considered as such, when it's concentration is less than 5% (wt, vol, at.) or when mentioned as such in the patent document to be classified.

In such a case, the compound is classified ignoring the dopant(s) and the last appropriate place rule does not apply in view of the dopant(s). In case of doubts, the document is given the class relating to the last appropriate place rule by taking into account the dopant(s) and in the appropriate class, without taking into account the dopant(s)

chemical compounds consisting of ceramic materials with iron(III) oxide (Fe2O3) as their principal component. Many ferrites are spinels with the formula AB2O4, where A and B represent various metal cations, usually including iron. Spinel ferrites usually adopt a crystal motif consisting of cubic close-packed (fcc) oxides (O2−) with A cations occupying one eighth of the tetrahedral holes and B cations occupying half of the octahedral holes—that is, the inverse spinel structure. Some ferrites have hexagonal crystal structure, e.g. barium ferrite BaO:6Fe2O3 or BaFe12O19.
Soft ferrites
Ferrites that contain nickel, zinc, and/or manganese compounds. They have a low coercivity and are called soft ferrites, e.g. Manganese-zinc ferrite (MnaZn(1-a)Fe2O4).
