  • Heat Treatment for Termites – Everything You Need

    Various insects have different thermal kill points. This is the minimum temperature that can kill an insect upon exposure within a specific amount of time. For example, Drywood termites will die in a 125F environment for at least 10 minutes. If the temperature is a notch higher at 130F, the termites will be eradicated for at least 6 minutes.

    OverviewTypesChemical reactionsHistoryIgnitionCivilian usesMilitary usesHazards

    Red iron(III) oxide (Fe2O3, commonly known as rust) is the most common iron oxide used in thermite. Magnetite also works. Other oxides are occasionally used, such as MnO2 in manganese thermite, Cr2O3 in chromium thermite, quartz in silicon thermite, or copper(II) oxide in copper thermite, but only for specialized purposes. All of these examples use aluminium as the reactive metal. Fluoropolymers can be used in special formulations, Teflon with magnesium or aluminium being a relatively common example.

  • How to make and deploy thermite for explosives, in

    Chemically, thermite requires two components with specific characteristics. One component, a metal such as aluminum, must have a chemical makeup with stable bonds. The second component, a metal oxide such as iron oxide (rust), must have less stable bonds. The metal (e.g. aluminum) acts as a reducing agent to extract metal (iron in this example) from the metal oxide (e.g. iron oxide). During ...
