Der Unterschied zwischen Aluminium, Primäraluminium, Elektrolytisches Aluminium, Aluminiumbarren, und Aluminiumoxid

Elektrolytisches Aluminium ist ein Verfahren zum Schmelzen von metallischem Aluminium. In der Regel, Aluminiumoxid wird durch einen großen Strom in einer Elektrolysezelle zu metallischem Aluminium zersetzt.

Aluminiumbarren können in drei Typen unterteilt werden: Barren aus hochreinem Aluminium, Barren aus Aluminiumlegierungen, und Aluminiumbarren zum Umschmelzen entsprechend ihrer Zusammensetzung;

Aluminium ist ein silberweißes Metall, and its content in the earth’s crust ranks third after oxygen and silicon. Aluminum has a low density, so it is called a light metal. Aluminum is a non-ferrous metal with high output and usage, second only to steel in the world. The density of aluminum is about 1/3 of that of steel and copper. Due to the light material of aluminum, it is often used in land, sea and air transportation such as trains, subways, Autos, airplanes, Schiffe, and rockets to reduce its own weight and increase its loading capacity. Similarly, aluminum also plays a significant role in military products.

Alumina, also known as aluminum oxide, is in the form of white powder. Primary aluminum is the liquid aluminum solution produced during the electrolysis process without precipitation and other treatments. The primary aluminum can become an aluminum ingot by entering the casting aluminum ingot model body for cooling treatment. Deswegen, alumina is the raw material of Yichu aluminum liquid, electrolytic aluminum is the process, Primäraluminium ist die Aluminiumflüssigkeit im Elektrolyseprozess, und Aluminiumbarren ist ein Aluminiumprodukt, das schließlich auf dem Markt verkauft wird.

Elektrolytaluminium ist durch Elektrolyse gewonnenes Aluminium. Die moderne elektrolytische Aluminiumindustrie verwendet Kryolith-Aluminiumoxid-Salzschmelzelektrolyse. Der geschmolzene Kryolith ist das Lösungsmittel, das Aluminiumoxid ist der gelöste Stoff, der kohlenstoffhaltige Körper ist die Anode, und die Aluminiumflüssigkeit ist die Kathode. Nachdem ein starker Gleichstrom angelegt wurde, the electrochemical reaction is carried out on the two electrodes in the electrolytic cell at 950°C-970°C. Both electrolysis.

Aluminum ingots for industrial use
The raw material in our daily industry is called aluminum ingot, which should be calledaluminum ingot for remeltingaccording to the national standard (GB/T 1196-2008), but everyone is used to calling italuminum ingot”. It is produced by electrolysis using alumina-cryolite. After aluminum ingots enter industrial applications, there are two categories: cast aluminum alloys and deformed aluminum alloys. Cast aluminum and aluminum alloys are aluminum castings produced by casting methods; wrought aluminum and aluminum alloys are aluminum processed products produced by pressure processing methods: plates, strips, foils, tubes, Stangen, shapes, wires and forgings. According to the national standardAluminum ingots for remelting are divided into 8 grades according to their chemical composition, namely Al99.90, Al99.85, Al99.70, Al99.60, Al99.50, Al99.00, Al99.7E, Al99. 6E” (Notiz: The number after Al is the aluminum content). Some people callA00” Aluminium, which is actually aluminum with a purity of 99.7%, which is calledstandard aluminumin the London market.

Alumina is a high-hardness compound with a melting point of 2054°C and a boiling point of 2980°C. It is an ionic crystal that can be ionized at high temperatures and is often used in the manufacture of refractory materials. Industrial Al2O3 is prepared from bauxite (Al2O3?3H2O) and diaspore. For Al2O3 with high purity requirements, es wird im Allgemeinen durch chemische Verfahren hergestellt.
