pyrotechnics - Best ways to start a thermite reaction? - Chemistry ...
2015年2月5日 · My son did thermite reactions for a 3rd. grade science project. We were able to easily initiate the reactions by using commercially-available thermite "fuses" which appear to be regular fuse that is about 2 inches long which then has a small, shiny square of metal about 1/2" x 1/2" and fuse product at the bottom.
Maximum temperature attainable by thermite reaction
In the thermite reaction $$\ce{2Al(s) + Fe2O3(s) -> 2Fe(l) + Al2O3(s)}$$ what is the maximum temperature attainable by the products? Assume reactants at $25\ \mathrm{^\circ C}$ and $1\ \mathrm{atm}$ and that all heat capacities remain constant. I started by using Hess's law to find the enthalpy change of the reaction.
Iron and copper oxide for thermite - Chemistry Stack Exchange
2020年7月12日 · Here is a comment on the nature of the Al/CuO thermite: 3.2. Nano-Aluminum/CuO Thermite Reaction in TJump/TOMFS. A more vigorous reaction of nano-Al was probed with a thermite mixture using CuO as the oxidizer at a heating rate of ∼5 × 10^5 K/s. where the use of the adjective 'vigorous' does not reflect, in my opinion, the intensity of the ...
inorganic chemistry - How is traditional thermite powder stored …
2019年2月1日 · Thermite powder is a heterogeneous mix and consists of fuel and oxidant, in you case aluminium $\ce{Al}$ and rust $\ce{Fe3O4}$. Separately, those can be corroded over time all right: aluminium can be oxidized and form aluminium(III) oxide, hydroxides and even some salts depending on what atmosphere thermite has been kept in.
Can thermite be lit while mixed into butane? If not is there a ...
2017年6月15日 · In addition to the points Stian raised, it's important to realize that thermite is very difficult to ignite. The ignition temperature is very, very high, higher than you can easily get by burning ordinary fuels such as butane, which means that whatever ignition method you use, if it's hot enough to ignite the thermite, would most likely set off the butane first, rather than at the …
Is it possible to make thermite that detonates? [closed]
2024年2月22日 · However, thermite is a mixture, not crystalline, and phonons scatter, making heat travel far slower -- as in pitch. Convection, where there is movement of material. When a brisant explosive detonates , material is ejected faster than …
inorganic chemistry - Testing thermite for chemical properties ...
2019年6月14日 · Typical military-grade thermite mixtures (e.g. used in incendiary hand grenades) contain a large amount of barium nitrate (e.g. 29.0 % in Thermate-TH3, see Patent No. US 6766744). It should be possible to detect the barium oxide that is left over after the fire, maybe first with a simple flame test on site followed by AAS (atomic absorption ...
How to efficiently reduce of ilmenite to pure titanium?

Thermite reaction beween zinc and iron (II, III) oxide
2017年4月8日 · I have zinc metal and iron oxide in the form of magnetite which I would like to obtain iron metal from. I was wondering if I could use a thermite reaction to create iron and zinc oxide? I would like to know whether such a reaction would occur between these two substances, how violent it is and whether the reaction will sustain itself?
Can molten aluminium be used to reduce iron oxide (rust) into iron?
2016年3月6日 · EDIT: I'm hoping one could use the molten aluminium instead of aluminium dust to achieve the same reaction as occurs in the Thermite process. I know about Thermite steel rail and copper earth connection welding. My goal is to reduce rust to iron by sprinkling it (with attendant sparks) onto a molten aluminium surface.
