In addition to thermite, thermate sometimes contains sulfur and sometimes barium nitrate, both of which increase its thermal effect, create flame in burning, and significantly reduce the ignition temperature.
[1] Various mixtures of these compounds can be called thermate, but to avoid confusion with thermate-TH3, one can refer to them as thermite variants or analogs.
The composition by weight of Thermate-TH3 (in military use) is 68.7% thermite, 29.0% barium nitrate, 2.0% sulfur and 0.3% binder (such as polybutadiene acrylonitrile (PBAN)).
As both thermite and thermate are notoriously difficult to ignite, initiating the reaction normally requires supervision and sometimes persistent effort.
As with thermite, thermate's ability to burn without an external supply of oxygen renders it useful for underwater incendiary devices.
