Aluminium diboride, also known as AlB2, is a compound that has a high theoretical burning heat, possesses a high melting temperature, has exemplary chemical stability, and exhibits remarkably good refinement of aluminum grains. This makes it suited for countless 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 boron dioxide or borofluoride, or through aluminum heat reaction. AlB2 Powder prepared by either of these two methods suffers from uneven particle size and form, which results in a reduction of 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 reaction materials to the liquid phase, and obtaining a uniformly mixed suspension by ultrasonic mixing. In order to resolve the problems above, the invention discloses an aluminum diboride preparation method, including: adding boron powder into the liquid phase through ultrasonic mixing, and getting a uniformly blended suspension; Wherein the precursor reactant raw materials include aluminum powder and boron powder; The uniformly-mixed suspension is then frozen to set. The solvent is then removed using vacuum freeze drying technology to get the treated precursor raw materials.
