DEFINITION

Classification: 106/470

Calcium silicate, e.g., dicalcium silicate or silicate hydrate, tobermorite, wollastonite, etc.:

(under subclass 466) Subject matter wherein the composition contains calcium silicate, e.g., dicalcium silicate, or silicate hydrate, tobermorite, wollastonite, etc.

(1) Note. A silicate compound containing both magnesium and calcium is not considered sufficient to place in this subclass. For such a composition see subclass 466.
