How is aluminum diboride AlB2 powder produced?
Aluminium buyers in the US physical metal market have held off on new orders amid fears of a recession triggered by rising inflation and supply chain crises.
Spot aluminium trading on the market has been suspended in recent weeks, according to industry sources, as uncertainty has increased following the outbreak of the conflict between Russia and Ukraine. Even before the war, the aluminium market was suffering from long waiting times and weak demand.
For aluminium buyers, recent poor US economic data have been a big factor in delaying purchases. Data released last month showed that the ISM manufacturing PMI came in at 57.1 in March, below expectations of 59 and down from 58.6 in February, unexpectedly hitting the lowest reading since September 2020. This was mainly due to a slowdown in new orders and Aluminum Diboride AlB2 Powder,Overview of Aluminum Diboride AlB2 Powder,Application of Aluminum Diboride AlB2 Powder,Aluminum boride AlB2 powder supplier,Aluminum boride AlB2 powder price are expected to increase in the future.
Overview of Aluminum Diboride AlB2 Powder
Aluminum boride (AlB2) is a binary compound formed by aluminum and boron. It is a red solid under normal temperature and pressure. It loses surface gloss when heated. Stable in cold dilute acid, decomposed in hot hydrochloric acid and nitric acid.
Aluminum boride (AlB2) is one of two compounds of aluminum and boron, the other being AlB12, which are commonly referred to as aluminum boride. AlB12 is a black glossy monoclinic crystal with a specific gravity of 2.55 (18°C). It does not dissolve water. The AlB2 single crystal is parallel to the hexagon of the substrate.
The structure of aluminum diboride (AlB2) is similar to that of 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. AlB2 single crystals exhibit metallic conductivity along an axis parallel to the hexagonal plane of the substrate.
Aluminum boride is considered a hazardous substance because it reacts with acids and hydrogen to produce toxic gases. For example, it reacts with hydrochloric acid to liberate borane and aluminum chloride.
The crystal structure of AlB2 is often used to describe the prototype structure of intermetallic compounds. There are various structural types in the AlB2 structural family.
A reducing solution is formed, soluble in dilute hydrochloric acid, the solution may contain HB(OH), insoluble in sulfuric acid but soluble in nitric acid. Above 920 degrees AlB2 is decomposed into AlB12.
Product Properties of Aluminum Diboride AlB2 Powder
Aluminum boride is an ionic compound with a hexagonal crystal structure. Aluminum boride with an absolute temperature of slightly 40K (equivalent to -233°C) turns into a superconductor. Its actual working temperature is 20 ~ 30K. To achieve this temperature, we can use liquid neon, liquid or closed cycle refrigerators to accomplish cooling. These methods are simpler and more economical than the current industrial use of liquid helium to cool niobium alloys (4K). Once doped with carbon or other impurities, magnesium diboride in a magnetic field, or with an electric current flowing through it, retains superconductivity as much as, or even better than, niobium alloys.
How is aluminum diboride AlB2 powder produced?
Using amorphous boron powder and aluminum powder as raw materials, aluminum boride powder is prepared by powder metallurgy method.
The phase composition, relative content and microscopic morphology of the product were determined by X-ray diffractometer and scanning electron microscope. The influence of buried powder on the phase composition of the product was studied, and the optimal process parameters of the synthesis process were determined. Decide.
The structure of aluminum boride is similar to that of intermetallic compounds, and its structure mainly depends on the crystal structure of aluminum metal and boron, rather than their valence relationship.
Diborosilane AlB2 shows that these two elements are formed by the reaction above 600℃. It is a layered structure in which Al atoms are directly overlapped (A, A-mode), and B atoms are filled in the triangular pillars formed by the direct overlap of Al atoms, that is, the boron layer is located between two aluminum layers.
The boron layer resembles a graphite structure. The boron atoms are connected in a hexagonal network. The distance between each B atom and the other three B atoms is 0.173 nm. There are six Al atoms attached to B, which are wrapped on top of the triangular pillars. AlB2 is soluble in dilute hydrochloric acid to produce a reducing solution, which may contain HB(OH)+3. AlB2 does not decompose dilute sulfuric acid, but decomposes in nitric acid. AlB2 decomposes to AlB12 above 920℃.

Recently, the first press conference of the Boao Forum For Asia Annual Conference 2022 was held. Two flagship reports were released at the conference: "Asia's Economic Prospects and Integration Process 2022" and "Sustainable Asia and the World 2022-Green Transformation in Action in Asia".
The flagship report points out that the global economy will recover in 2021, and the pace of economic integration in the Asia-Pacific has not stopped even in the face of the impact of COVID-19. The Asia-Pacific region has provided new impetus for the world's economic recovery and institutional building.
The report gives an outlook on the Asian economy, noting that a number of factors will affect Asian economic growth. For example, mutated strains such as Delta and Omicron have become more transmissible, and many economies are experiencing epidemic peaks again. The Ukraine crisis has triggered geopolitical changes in Asia and Europe, leading to higher commodity prices, which may affect the global energy supply and energy transformation.
The report pointed out that the Asian economy will still be in the process of recovery in 2022, but the growth rate may moderate. According to the report, Asia's economic growth in 2022 is likely to be lower than the current IMF forecast, which is projected at 4.8%.
Affected by several factors, the supply of the Aluminum Diboride AlB2 Powder,Overview of Aluminum Diboride AlB2 Powder,Application of Aluminum Diboride AlB2 Powder,Aluminum boride AlB2 powder supplier,Aluminum boride AlB2 powder price is erratic and thus its prices are expected to go higher in the future.
