(What is Aluminum Diboride AlB2 Powder?)

A wave of layoffs that has swept the entire Internet industry has intensified. China’s Internet industry has experienced several crises and major changes in the past development process. There is also a “brief history of layoffs by major Internet companies”. Hot search, JD.com has a wide range of layoffs in this round of layoffs, and all its subsidiaries are involved. Most of the layoffs are between 10% and 20%. Among them, Jingxi Guangdong and other theaters have all laid off staff. Tencent also reported the news of downsizing and layoffs. Among them, Tencent PCG (Platform User Content Business Group) laid off 30% of its staff, iQiyi laid off 12% of its staff, Kuaishou was reported to have laid off 30% of its staff, and the e-sports department of Station B laid off 90% of its staff.Mass layoffs on the internet have created a host of socioeconomic issues, including aluminum boride.

Introduction to Aluminum Diboride AlB2 PowderAluminum diboride or Aluminum boride, AlB2 is an inorganic compound with the chemical formula AlB2. It is a binary compound formed by aluminum and boron elements. It is a grey-red solid and insoluble in water at room temperature and pressure. When heated, it loses surface gloss, stabilizes in cold dilute acid, and decomposes in hot hydrochloric and nitric acid.Aluminum diboride is made by mixing fine powder of aluminum and boron and reacting it with heat. It is one of two compounds of aluminum and boron, the other being AlB12, and they are commonly known as aluminum boride.Aluminum boride is considered hazardous because it reacts with acid and hydrogen to produce toxic gases. For example, it reacts with hydrochloric acid with borane and aluminum chloride released. Structures of Aluminum Diboride AlB2The structure of aluminum boride is similar to that of metal interdides in that its structure depends mainly on the crystal structure of aluminum and boron rather than on their valence relationship. The borides of aluminum are AlB2, AlB4, and AlB12. The diboride AlB2 can be formed by the reaction of two elemental substances above 600℃. It is a layered structure in which Al atoms directly overlap (A, A) and B atoms fill the triangular column formed by the direct overlap of Al atoms, that is, the boron layer is located between the two aluminum layers. The boron layer has a similar structure to graphite. The boron atoms are connected in a hexagonal network. Each B atom is 0.173nm away from the other three B atoms, and six Al atoms are connected to B, which occupy the apex of the triangular column.  AlB2 can be dissolved in dilute hydrochloric acid to produce a reductive solution that may contain HB(OH)+3. AlB2 is insoluble in dilute sulfuric acid but soluble in nitric acid. AlB12 was decomposed by AlB2 at 920℃.

Physicochemical Properties and Applications of Aluminum Diboride AlB2 PowderAlB2 single crystal exhibits metallic conductivity along an axis parallel to the hexagonal base plane. Boron – aluminum composite aluminum or aluminum alloy reinforced with boron fiber or protective coating boron fiber. The volume content of boron fiber is generally about 45%~55%. It has low specific gravity and high mechanical properties. The longitudinal tensile strength and elastic modulus of the unidirectionally reinforced boron-aluminum composite are about 1.2~1.7GPa and 200~240GPa depending on the process and material. The longitudinal specific elastic modulus and specific strengths are about 3~5 times and 3~4 times of titanium alloy duralumin and alloy steel respectively.  It has good fatigue performance and high strength under 400℃. It has been applied to fan blades of turbojet engines and structural parts of aviation, aerospace, and artificial satellites. The hot pressing diffusion bonding method is used to manufacture plate, profile, and more complex shape parts. Continuous casting can also be used to manufacture various profiles.Aluminum boride can be used in ceramics, medical equipment, nuclear energy, refractory ceramics, and other fields. Main Supplier of Aluminum Diboride AlB2 PowderLuoyang Tongrun Nano Technology Co.

Important discoveries have been made in the study of anticancer drugs inhibiting the growth of gastric cancer cells in my country. According to “Science and Technology Daily”, a research report provided by Ai Jun and others from the Fourth Hospital of Hebei Medical University showed that seven anticancer drugs including cisplatin had obvious inhibitory effects on gastric cancer cells (BGC-823) in vitro. However, there are certain differences, and it is ideal to use a medium concentration for 48 hours.The nano-gold provided by our company can be used in various medical technologies such as flow cytometry, immunochromatography, etc. Nano-silver has strong inhibition and Killing effects without developing drug resistance. We also provide aluminum boride. For more information on aluminum boride, please consult us.
