DEFINITION

Classification: 75/959

THERMIT-TYPE REACTION OF SOLID MATERIALS ONLY TO YIELD MOLTEN METAL:

Art collection of patents in which a mixture of solid materials including a reducible metal compound and a solid reducing agent are reacted so that the heat of reaction is sufficient to yield the reduced metal in molten condition.

(1) Note. A common example is the reaction of Iron oxide and Aluminum (Al) powder which proceeds with sufficient vigor to produce Iron in molten form.

(2) Note. Excluded herefrom are patents which treat molten metal with compositions which have ingredients which interact exothermically. For such patents see the appropriate subclass above relating to the treatment of the particular molten metal involved.
