Background Technology

Aluminium diboride, also known as AlB2, is characterized with high theoretical burning heat, 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 or borofluoride, or through aluminum heat reactions of aluminum and boron or borofluoride powder. AlB2 Powder prepared by either of these methods suffers from uneven particle size and form, resulting to a reduction in the performance of AlB2 Powder. 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 aims to solve these problems by providing an aluminum diboride and its preparation method that can control particle size and shape and ensure good performance. To solve the problems above, the invention discloses an aluminum diboride preparation method, including: adding boron powder into the solvent phase of the liquid phase; getting the evenly mixed powder through ultrasonic mixing. The precursor reaction ingredients include aluminum and boron powder. The uniformly blended suspension is then frozen to set. The solvent is then removed by vacuum freezing-drying technique to obtain treated precursor raw materials.
