Preparation of aluminum diboride powder

Using amorphous boron powder and aluminum powder as raw materials, powder metallurgy is used to prepare AlB12 powder. X-ray diffractometer and scanning electron microscope were used to determine the phase composition, relative content and micro morphology of the product, to study the influence of embedded powder on the phase composition of the product, and to determine the best process parameters for synthesis.

The structure of aluminum boride is similar to intermetallic compounds, and its structure mainly depends on the crystal structure of aluminum metal and boron rather than their valence relationship. The aluminum borides are AlB2, AlB4 and AlB12.

The two elements react above 600℃ to form aluminum diboride AlB2. It is a hierarchical structure. Al atoms directly overlap (A, A mode), and B atoms are filled in the triangular column formed by the direct overlap of Al atoms, that is, the boron layer is located between the two aluminum layers.

Aluminum diboride: It is a binary compound formed by aluminum and boron, and its chemical formula is AlB2. Aluminum diboride is a red solid under normal temperature and pressure.

Characteristics of aluminum diboride powder

Aluminum diboride loses its surface gloss after heating, is stable in cold dilute acid, and decomposes in hot hydrochloric acid and nitric acid. Aluminum diboride is obtained by mixing fine powders of aluminum and boron after heating.

Aluminum boride is one of two compounds of aluminum and boron, the other is AlB12, and they are commonly referred to as aluminum boride. AlB12 is a black shiny monoclinic crystal with a specific gravity of 2.55 (18°C). It is insoluble in water, acid and alkali, and decomposes in hot nitric acid. It is obtained by melting together boron trioxide, sulfur and aluminum.

In structure, B atoms form graphite-like flakes with Al atoms in between, which are very similar to the structure of magnesium diboride. The aluminum diboride single crystal exhibits metallic conductivity on an axis parallel to the hexagonal plane of the substrate.

Aluminum boride (AlB2) is a binary compound formed by aluminum and boron. It is a red solid under normal temperature and pressure. The surface gloss will be lost when heated. It is stable in cold dilute acid and decomposes in hot hydrochloric acid and nitric acid. It is obtained by mixing fine powders of aluminum and boron and heating them.

It is one of two compounds of aluminum and boron, the other is AlB12, commonly known as aluminum boride. AlB12 is a black shiny monoclinic crystal with a specific gravity of 2.55 (18°C). Insoluble in water, acid and alkali. It decomposes in hot nitric acid and is obtained by melting together boron trioxide, sulfur and aluminum. The single crystal of AlB2 is parallel to the hexagon of the matrix.

Aluminum boride is considered a hazardous substance because it reacts with acid and hydrogen to produce toxic gases. For example, it reacts with hydrochloric acid to release borane and aluminum chloride. The structure of aluminum diboride (AlB 2) is similar to graphite flakes. There is an Al atom between the B atom and the B atom, which is very similar to the structure of magnesium diboride. The AlB 2 single crystal exhibits metal conductivity along an axis parallel to the hexagonal plane of the substrate.

Aluminum boride is considered a hazardous substance because it reacts with acid and hydrogen to generate toxic gases. For example, it reacts with hydrochloric acid to release borane and aluminum chloride.

The crystal structure of AlB2 is often used to describe the prototype structure of intermetallic compounds. There are many structure types in the AlB2 structure family.

Aluminum boride is an ionic compound with a hexagonal crystal structure. Aluminum boride with an absolute temperature of 40K (equivalent to -233°C) will be transformed into a superconductor. Its actual working temperature is 20~30K. To reach this temperature, we can use liquid neon gas, liquid or closed-cycle refrigerators to complete the cooling. Compared with the current industry that uses liquid helium to cool niobium alloys (4K), these methods are simpler and more economical. Once carbon or other impurities, magnesium diboride, or energization are added to the magnetic field, the ability to maintain superconductivity is as much as that of niobium alloys, or even better.
