Why is AlMgB14 powder so rare?

What is AlMgB14 powder?
AlMgB14 powder has been found to have extremely high hardness (32-35GPa), low density 2.66g/cm3, good wear resistance, low friction coefficient, electrical conductivity, and high-temperature oxidation resistance since the first synthesis of aluminum, magnesium, and boron; there have been many relatively mature synthesis methods. However, aluminum, magnesium, and boron materials still need to be widely used in real life, mainly because of the hardness and fracture toughness of AlMgB14 powder and their instability. Therefore, improving the hardness and fracture toughness of AlMgB14 materials is urgent. AlMgB14 powder material has excellent comprehensive properties such as high hardness, low density, high-temperature oxidation resistance, and low friction coefficient. It has significant application value in tools, dies, micromachine manufacturing, and critical aerospace components.

Method of preparing AlMgB14 powder
Mechanical alloying hot pressing sintering method, plasma discharge sintering method, high temperature, and atmospheric pressure synthesis (HTS) method are used to prepare single-crystal AlMgB14 powder: metal salt preparation method, crystallization deposition method, mechanical alloying hot pressing sintering method is to put the element powder into a high-energy ball mill for ball milling, and then hot pressing sintering under inert atmosphere protection to prepare densified bulk AlMgB14 powder Cook, a researcher at Amos Laboratory under the US Department of Energy, and others were the first to prepare AlMgB14 powder by this method The disadvantages of mechanical alloying hot pressing sintering method are high energy consumption, high cost, considerable iron pollution caused by quenched steel balls during ball milling, many influencing factors, complex process, and challenging to control. The advantage is that it can obtain ultra-fine powder mixed materials with a phase particle size of about 100 nm. It is very suitable for pressure-assisted sintering and can almost achieve complete densification.
AlMgB14 powder stone:
AlMgB14 powder has been regarded as brown olivine for a long time. In 1952, X-ray analysis confirmed that it was new mineral and renamed bauxite. The molecular formula is MgAl [BO4], a borate mineral. Columnar crystal Mohs hardness is 6.5 to 7. Density 3.47 to 3.50g/cm. Refractive index 1.67 to 1.71. Glass luster Very light yellow to brown, light maroon and light brown green, rarely colorless, with obvious polychrome. The colors are golden brown, green-brown, and dark brown.
Price of AlMgB14 powder
AlMgB14 powder particle size and purity will affect the product's Price, and the purchase volume can also affect the cost of AlMgB14 powder. A large amount of large amount will be lower. The Price of AlMgB14 powder can be found on our company's official website.
