Het verschil tussen aluminium, primair aluminium, elektrolytisch aluminium, aluminium blokken, en aluminiumoxide

Electrolytic aluminum is a method of smelting metal aluminum. Gebruikelijk, aluminum oxide is decomposed into metal aluminum by a large current in an electrolytic cell.

Aluminium blokken kunnen worden onderverdeeld in drie soorten:: high-purity aluminum ingots, aluminum alloy ingots, and aluminum ingots for remelting according to their composition;

Aluminium is a silver-white metal, 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, automobiles, airplanes, ships, 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. Primair aluminium is de vloeibare aluminiumoplossing die wordt geproduceerd tijdens het elektrolyseproces zonder neerslag en andere behandelingen. Het primaire aluminium kan een aluminium staaf worden door het modellichaam van het gegoten aluminium staafmodel binnen te gaan voor koelbehandeling. Daarom, aluminiumoxide is de grondstof van Yichu aluminiumvloeistof, elektrolytisch aluminium is het proces, primair aluminium is de aluminiumvloeistof in het elektrolyseproces, en aluminiumstaaf is een aluminiumproduct dat uiteindelijk op de markt wordt verkocht.

Electrolytic aluminum is aluminum obtained by electrolysis. The modern electrolytic aluminum industry uses cryolite-alumina molten salt electrolysis. The molten cryolite is the solvent, the alumina is the solute, the carbonaceous body is the anode, and the aluminum liquid is the cathode. After a strong direct current is applied, 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
De grondstof in onze dagelijkse industrie wordt aluminiumstaaf genoemd, die moet worden genoemd “aluminium staaf om opnieuw te smelten” volgens de landelijke norm (GB/T 1196-2008), maar iedereen is gewend om het te noemen “aluminium staaf”. Het wordt geproduceerd door elektrolyse met alumina-kryoliet. Nadat aluminium blokken industriële toepassingen hebben bereikt, er zijn twee categorieën: gegoten aluminiumlegeringen en vervormde aluminiumlegeringen. Gegoten aluminium en aluminiumlegeringen zijn aluminium gietstukken die worden geproduceerd door middel van gietmethoden; wrought aluminum and aluminum alloys are aluminum processed products produced by pressure processing methods: plates, strips, foils, tubes, rods, 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” (Note: 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, it is generally prepared by chemical methods.
