Abstract

In one embodiment, thermite matches are provided. For instance, thermite matches as described herein may be constructed as a multi-staged formulation comprising an outer ignition tip, an optional inner transition tip, and a bulk fuel thermite stage. The outer ignition tip may comprise an ignition compound that can be struck/scraped against an abrasive counter-chemical surface (e.g., red phosphorous) to initiate the reaction. The outer ignition tip can reach a first burn temperature that can further ignite the inner transition tip stage, which can in turn burn at a temperature that reaches the ignition temperature of the bulk fuel thermite. The high burn temperature of the thermite match may then be used to ignite other materials, such as hard-to-ignite materials, such as a thermite rod for cutting or welding. Other embodiments provide for thermite match handles and a two-piece ignition thermite matches.

Dependent claims

A thermite match, comprising:

a handle having a first end and a second end;
a thermite material affixed to the second end of the handle, the thermite material having a thermite ignition temperature and a thermite burn temperature;
an intermediate transition material disposed at a distal end of the thermite material away from the handle, the intermediate transition material having an intermediate ignition temperature and a burn temperature at least equal to the thermite ignition temperature;
and
an outer ignition tip disposed at a distal end of the intermediate transition material away from the handle, the outer ignition tip having an ignition property that is more ignitable than both the intermediate transition material and the thermite material, the outer ignition tip further having a burn temperature at least equal to the intermediate transition material, wherein ignition of the outer ignition tip causes ignition of the intermediate transition material which further causes ignition of the thermite material.
