DEFINITION

Classification: 524/442

Soil or inorganic silicon DNRM (other than silicon dioxide, glass, quartz, novaculite or silicon dioxide type):

(under subclass 80) Subject matter wherein a solid polymer or specified intermediate condensation product is admixed with a designated nonreactant material which is an inorganic compound containing silicon.

(1) Note. Soil is by definition an inorganic silicon containing material although it may contain certain organic values.

(2) Note. SiO2 (quartz, novaculite and other silica type material) and glass have been excluded from this subclass and have been classified below on some other basis.

492, for glass or silica having numeric limitations, and appropriate subclasses for the admixture of a nonnumerically defined glass or SiO2, and a solid polymer or SICP.
