DEFINITION

Classification: 117/68

Having growth from a solution comprising a solvent which is liquid at or below 20 degrees Celsius (e.g., aqueous solution):

(under subclass 11) Subject matter in which the crystallizing material is present in a solution with another material which is a liquid at or below 20 degrees Celsius.

(1) Note. See the (5) Note located in subclass 13 for discussion of distinguishing characteristics among several liquid phase processes.

(2) Note. When the disclosure is generic to liquid solutions and it is not clear whether the solvent is liquid at room temperature, search and cross-references are appropriate here and in subclasses 73+.

SEE OR SEARCH THIS CLASS, SUBCLASS:

13+, for processes of growing while pulling crystals from a liquid which may be liquid at room temperature.
