DEFINITION

Classification: 524/492

Mixing inorganic silicon-containing material having color or numerical limitations other than amount, e.g., included herein are m.p., chemical composition, particle size, surface area, etc., or composition or product thereof, DNRM:

(under subclass 1) Subject matter wherein the designated nonreactant material is an inorganic silicon-containing material having claimed numerical limitations other than amount, e.g., m.p., particle size, etc., or wherein the claim recite a special color or composition or product thereof.

SEE OR SEARCH THIS CLASS, SUBCLASS:

498, through 612, for a particular crystalline structure of a silicon inorganic compound, e.g., novaculite, quartz, etc., wherein the claims fail to recite a numerical limitation.

847, for a process of polymerizing in the presence of a silicon inorganic DNRM which may be novaculite, quartz, etc.
