Background Technology

Aluminium diboride, also known as AlB2, is characterized with high theoretical burning heat, a high melting temperature, good chemical stabilities, and a good refining of aluminum grains. This makes it an excellent material for many different applications. AlB2 has many applications, including particle enhancers to improve wear resistance, hydrogen storage materials, solid propellants, etc. AlB2 is currently prepared in two ways: by direct solid phase sintering between boron powder, aluminum powder, and boronoxide, or by aluminum-heat reaction with aluminum powder, borofluoride, and boronoxide. AlB2 Powder prepared using either of these two methods can have uneven particle shape and size, which will reduce the performance. There is a need for a method that can prepare AlB2 Powder with uniform size. This will allow the powder to be controlled in particle size and shape and provide good performance.

Technical Implementation Element

The invention discloses an aluminum diboride preparation method that includes the following steps: adding the precursor reactions raw materials to the liquid phase, and getting a uniformly mixed suspension by ultrasonic mixing. The invention discloses an aluminum diboride preparation method that includes the following steps to solve the problems above: adding the boron powder into the solvent phase of the liquid phase; getting the evenly mixed powder through ultrasonic mixer; the uniformly blended suspension is then frozen to set; and the solvent is then removed by vacuum freezing-drying technique to obtain treated precursor raw materials.
