It is a 1:3 ratio of aluminum oxide and black iron oxide (respectively, and is the best mix)
Yes, aluminum oxide can be used as a substitute for iron oxide in thermite reactions. However, it is less commonly used because it requires a higher temperature to initiate the reaction compared to iron oxide.
Thermite is easy to make, just mix fine powdered aluminum powder (400 mesh) with fine powdered iron oxide, the ratio is 1:2. Its better to light it with a magnesuim strip. The ingredients can be bought on eBay.
It is called the thermite reaction, and it's expressed this way: Fe2O3 + 2Al -> 2Fe + Al2O3 + Heat A link can be found below. It's to the Wikipedia post, and you'll get more information there.
Thermite is a pyrotechnic composition of a metal powder and a metal oxide, which produces an aluminothermic reaction known as a thermite reaction. It is not explosive, but can create short bursts of extremely high temperatures focused on a very small area for a short period of time.

Copper thermite is a type of thermite where instead of the iron oxide, copper oxide is used instead. The reaction produces pure copper metal, but this thermite gets a little more splattery than the iron thermite.
Thermite is manufactured from pure metals and avoiding the use of carbon in the process of it. Thermite was originally discovered by a German chemist named Hans Goldschmidt.
Thermite itself is not illegal, but it is highly regulated because of its potential for misuse. Special permits or licenses may be required to possess, use, or transport thermite. It is important to check and comply with local laws and regulations before obtaining or using thermite.
Thermite reaction is used in industry for welding steel together in-place
Thermite is a mixture of 1 part aluminum oxide for every 3 parts iron oxide
For the classical iron oxide and aluminum thermite, the products of the reaction are aluminum oxide (Al2O3) and iron (Fe). However, there are many kinds of thermite, but they always produce the pure metal from the oxide.
Thermite has its own oxygen source so it can burn without an outer source of oxygen, including underwater and in the vacuum of space. However, I do doubt that thermite can burn in space, since space is quite cold. It would just depend in how far away from the Sun you are when you light the thermite.
It is ilegal
Thermite is not specifically illegal in Kansas, but it is classified as an incendiary device and its use is regulated by federal and state laws. Using thermite inappropriately or causing harm or damage with it can lead to legal consequences in Kansas.
Thermite is not an explosive. However, most types of thermite, especially copper, burns very hot and fast, and can splatter molten metal all over the place. It doesn't go boom like a pack of TNT, but it is still pretty dangerous.
Attempting to put out thermite with water is dangerous since it can create an explosive reaction due to its extreme heat. The safest way to handle a thermite reaction is by letting it burn out on its own in a controlled environment. Using a Class D fire extinguisher specifically designed for metal fires could also be effective in extinguishing thermite.
