ABSTRACT:
The present invention is directed to the encapsulation of pyrophoric materials in a high temperature resistant membrane having at least one perforation which allows air to contact the pyrophoric material. By controlling the accessibility of the pyrophoric material to the surrounding air, it is possible to reduce the kinetics of the oxidation reaction without affecting the thermodynamics of the reaction. This results in a product that demonstrates a lower peak temperature, longer dwell time at the lower temperature and, in most cases, an increase in the total heat energy output in comparison to an identical pyrophoric material that is not so encapsulated.
