Behavior and Combustion Properties when Aluminum Paste is Heated

Description

Behavior and Combustion Properties when Aluminum Paste Is Heated, by T. Meguro, N. Torikai, and Y. Kobayashi, Y., Keikinzoku (J. Japan Institute of Light Metals) 29:5, 173-178 (1979). English translation from Japanese.

Combustion tests were carried out on aluminum pastes containing 50 to 90 wt% aluminum powder and aluminum powders, stamped and atomized, to examine the safety of aluminum pastes on fire. The tests included heating up to 800 degrees C in an electric furnace, burning in a gas burner flame, and firing in a porcelain crucible by using a gas burner. Solvents in the pastes are only combustible and any indications of the dust explosion are unrecognized. Coagulation of the aluminum powders is found. Violent ignition takes place after combustion has completed in the crucible in which the stamped powder is filled. The aluminum pastes resemble petroleum in combustion properties.
