Aluminum Carbide

Aluminum carburide also known by the name three-carbon-four-aluminum has a molecular form of AL4C3, a type aluminum carbide. It is a yellow-brown transparent, hard, rhombohedral, crystal. It is a rhombohedral ionic crystalline material that does not conduct electrical current at room temperature.

Aluminum Carbide:

Calcium carbide contains a small amount aluminum carbide. Aluminum carbide is often produced by corroding graphite electrodes when metal aluminum is melted using electrolysis. Aluminum carbide can be an unwanted component of metal matrix composites, or carbon fibres, that use aluminum to create the matrix. Carbon fiber and aluminum composites are examples of materials that can react when the temperature is above 500. It can be prevented from reacting chemically if it is coated with titanium boride. In the silicon carbid reinforced aluminum-based material, the chemical reactions between silicon and aluminum melt produce a layer or aluminum carbide that covers the surface the silicon particles. This can be prevented by coating the silicon particles with a suitable oxide, nitride or other material.

Synthesis of Aluminum Carbon

Aluminum carbide Al4C3 may be produced by direct reaction of two elements at high temperature. Mix 1 part heavy black smoke and 6 parts aluminum powder. Moisten the mixture with pine oil. Spread a thin layer of carbon on top. The crucible is covered with a cover and all gaps are smeared in refractory dirt mixed with asbestos fibres. After pre-drying the crucible, the mixture must be heated to a temperature no lower than 1200°C for 30 min. Higher temperatures can improve the reaction. After cooling, the product will be treated with diluted alkaline or hydrochloric acids (or dilute hydrochloric solution) to remove any excess aluminum. After obtaining the aluminum carbide as a fine powder, it is washed to remove aluminum chloride with water. Alcohol is then used to quickly wash away the water. The product is then dried in a box set at a temperature between 80 and 90 degrees. The product contains an excessive amount of aluminum chloride.


Aluminum carbide itself is colorless. However, the products that are made using the above method can have different colors because of impurities. Calculated amounts of the mixtures of aluminum and soot can be calcined using hydrogen to produce a pure aluminum carbide without aluminum nitride. This calcination must be performed at a temperature between 1800-1900 for 23 hours. The ground product is calcined once again at the same temperature.

What happens when aluminum carbide reacts with other material?

What is Aluminium Carbide? Aluminum carbide is an organic compound. The molecular formula for aluminum carbide is Al4C3. It is yellow or green-gray crystal blocks or powder and has a molecular mass of 143.96. Hydrolysis in cold water to methane, decomposition at high temperatures and aluminum hydroxide.
What happens when aluminum carbonide reacts with water
Aluminum carbide has four carbon atoms in each aluminum atom, which gives it a tetrahedral structure. It is stable to 1400°C. It can be broken down in water, and it produces methane. From the above reactions, it is clear that aluminum carbide can be broken down in the water and formed methane.
What happens when aluminum reacts to carbon?
Aluminum can combine with carbon, nitrogen and sulfur at high temperatures to make the appropriate aluminum compounds. Aluminum carbide (Al4C3) is a form of pale yellow crystals. It can be heated by heating a mixture from these elements at higher temperatures than 1000°C.
Aluminum carbide preparation
Coke and alumina in electric furnace heating.
Aluminum carbide Al4C3 comes from a combination of two elements at high temperature.
Mixture of one part heavy smoking black and six parts aluminum powder was prepared. It was moistened by pine essential oil and placed in a tight layer inside a clay crucible. Finally, it was sealed with toner. All gaps should be filled with refractory earth mixed with asbestos fibers. The mixture was placed into a crucible and pre-dried. For 30 minutes, the mixture was heated to 1200 F. A higher temperature is better for the reaction. After cooling, the product can be treated with dilute chloric acid (or an Alkaline solution) to remove excess aluminium. Aluminum carbide is prepared as fine crystal powder. It is then washed with water to remove any aluminum chloride. Finally, the product is quickly washed and placed in a drying oven at 90 80 degrees for drying. It contains a lot of aluminum nitride.
Pure aluminum carbide is inert, but the products that are made using this process can have different colors from those produced by other impurities.
Pure products without aluminum nitride are possible when they are calcined with hydrogen. This takes about 2 to 3 hours and is done at 1800 1900. The prepared product can be ground again and calcined at above temperatures.
What’s the difference in Al4C3 and CaC2?
Answer: Most likely beryllium carbonide [Be2C]. And aluminum carbide[Al4c3]. Beryllium oxide (Be0) reacts with carbon at 2000degC [3600degF] in order to form brick-like Beryllium carbide. While the pale yellow aluminum caride is made from aluminum and carbon in an oven,

About Titanium Aluminum Carbide Ti2AlC Powder:
Titanium aluminum carbide powder, also known as titanium aluminum carbon, is a kind of better grain refiner for aluminum developed in the recent 20 years. Titanium carbide is a member of the Max phase ceramics family. In the oxidation process of titanium aluminum carbide (Ti3AlC2), the selective oxidation of Al can generate continuous Al2O3 protective film. The experimental results also show that the titanium aluminum carbide (Ti3AlC2) has excellent thermal cycling resistance, and the oxide film generated is compact, well combined with the matrix, and does not peel off. The oxide film of titanium silicon carbide (Ti3SiC2) at high temperature is divided into two layers, the outer layer is TiO2, the inner layer is a mixture of TiO2 and SiO2, the density of the oxide film and the adhesion with the matrix are good.

The Al in the MAX phase of the Ti-Al-C system can rapidly diffuse and selectively oxidize to form a dense Al2O3 film in the oxidation process, which prevents the matrix material from further oxidation. The microstructure of the interface between Ti3AlC2 and Ti2AlC and the generated Al2O3 makes the system material possess high-temperature self-healing ability. In the high-temperature environment, the cracks or marks on the surface of the material are filled with this oxide, so that the material can restore the original properties, especially the mechanical properties. This characteristic is of great significance for maintaining the mechanical properties of materials and improving the stability and reliability of materials, which makes them more likely to be applied in a high-temperature environment.

The rapid Al diffusion and selective oxidation properties of titanium aluminum carbide (Ti3AlC2 and Ti2AlC) at high temperatures realize the welding of the material itself and the welding between layers, respectively. Compared with single-phase materials, the fracture toughness of laminated Ti3AlC2 and Ti2AlC materials obtained by self-welding is greatly improved.

Applications of Titanium Aluminum Carbide Ti2AlC Powder:
Similarly, using the weak bond between Al lamellas and TiC lamellas in the Max phase of titanium aluminum carbide (Ti3AlC2), the use of hydrofluoric acid (HF) can be used to denude Al in titanium aluminum carbide (Ti3AlC2) to produce a new two-dimensional carbide, called “MXENE”, whose morphology is similar to that of graphene. Maxine’s excellent conductivity makes it possible to be used as a lithium-ion battery material.

Max phase products, especially titanium silicon carbide (Ti3SiC2) have a series of characteristics such as high damage tolerance, good mechanical and thermal properties, which make it possible to be used in the fourth-generation nuclear reactor as the nuclear fuel cladding material in a gas-cooled fast reactor. In recent years, more and more attention has been paid to the anti-radiation damage ability of titanium silicon carbide (Ti3SiC2).
