Aluminum carbide overview Aluminum carbide is one of the most abundant elements in the earth's crust. Aluminum carbide is used extensively in industry due to its good formability and lightweight. Aluminium and its alloys face the problems of weak strength, low wear resistance and poor performance at high temperatures. Aluminum carbide, also known as Al4C3, is an ionic chemical with a diamond hexahedral design. This structure makes it an excellent second-phase material to strengthen aluminum-based materials.

The hexagonal flake crystal of aluminum carbide-gold hexagonal isotope. This crystal had a relative density of 2.36. It is stable at 1400 but decomposed after 2200.
What happens when Aluminium carbidide reacts with liquid water? Aluminum carbide (Al4C3) reacts with water and forms methane (CH4). You can write the chemical reaction as Al4 C3 +12H2 OH-4Al(OH),3 +3CH4 If water is being decomposed to make methane, store it in dry shade. This is done by heating aluminum powder and pure carbon. Presently, aluminum carbide can be prepared using a variety of methods, including direct metal carbonization and carbon thermal reduction.


Aluminium carbide preparation method

These are two of the oldest synthetic methods. In fact, some of them have been used in industrial production. The disadvantages to these methods include high synthesis temperature and long reaction times as well as large particle sizes. In the well-known high-energy grinding method, however, the emphasis is on the in situ synthesis and enhancement of small amounts of Al4C3 in order to increase the quality of aluminum-based products, not the high-purity Al4C3 synthesiztion. The disadvantages of the high energy ballmill include a long ball grinding process, large energy consumption and uneven particle size.

These steps are used to make aluminum carbide powder through plasma ball grinding.

(1) The mixture of graphite and aluminum powder was easily mixed and then the powder was refined and activated by a plasma ball mill, protected with argon. It is possible to start and stop alternately every 30 minutes.

(2) Once the ball mill has mixed powder, cover it with alumina crucible. Next, the tube furnace vacuum is turned on. Argon gas is piped into the tube furnace at 100 ml/min. After four hours, the temperature will reach 1000. Finally, the air cooling tube furnace cools to room temperature in 100 minutes. This is an SEM Diagram of Aluminum Carbide Powder.

Use of aluminum carbide

Where is aluminum carbide used? Aluminum carbide is used often to improve the strength and stability of three-component aluminum materials (al si-Al4C3, al alti-Al4C3). Al4C3 can also be used as an additive in three-component aluminum-based materials (al-siAl4C3, al–altiAl4C3). This compound is important in the technical area of the aluminium metal industry. Al4C3 is an ionic compound. Carbon atoms can exist separately as C atoms. The strong alkalinity of C is evident. C+4HCH produces methane, and Al4C3 also serves as a dehydrator and methanogen. These unique structures make Al4C3 Nanowires, which are one-dimensional Al4C3, a possibility cold electron emitter.

1) Preparation of aluminum nitride based on aluminum carbide, including (b). Aluminum carbide is heated in ammonia gas or flowing water to reach a temperature that can be measured and then kept at room temperature for some time. To make aluminum nitride, aluminum carbide reacts in high temperatures with ammonia and nitrogen gas. With the invention aluminum nitride is possible to be produced at relatively low temperatures. It has high purity, small particles size, uniform particle distribution and high thermal conductivity. These properties can be used extensively in integrated circuit substrate materials.

2) Preparation of an aluminum carbide-nanoribbon. Once the al-si alloy crucible was in place, the door was shut and it was heated up to 50Pa10-3pa. After that, the temperature was increased to 7001600. Next, the temperature was lowered to 1-20 degrees. Finally it was naturally cool to room temperature. The invention yields a thinner aluminum carbide macroribbon and contains less impurities.

Aluminium carbide storage conditions

When aluminum carbide is in contact with water, it will release methane. Heat or fire may cause the gas to ignite and can result in a rapid reaction. You can see it reacting with acids. You should store it in a well-ventilated, cool warehouse. You should keep it away from heat and flames. Relative humidity should not exceed 75% Seal the packaging. The packaging should be kept away from acids. To prevent spills, the storage space should be fitted with appropriate materials.
