DEFINITION

Classification: 60/216

(under subclass 215) Process in which the fuel contains a free metal.

(1) Note. The term "metal" includes free metal (e.g., calcium), an alloy of two or more metals (e.g., 90% Al,10% Mg), an intermetallic compound (e.g., AlNi) or a mixture of particles of two or more metals (e.g., mixture of Mg shot, Fe powder and Al turnings).

(2) Note. Processes within the scope of subclasses 205+, utilizing fuel slurries which are classified elsewhere should be cross-referenced to this subclass.
