Background Technology
Aluminium diboride, also known as AlB2, is a compound that has high theoretical burning heat, a melting point of 900°C, and possesses good chemical stability. This material can be used in many different fields due to its high application potential. 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 borofluoride, or through aluminum heat reaction. AlB2 Powder prepared by either of these two methods suffers from uneven particle size and form, resulting 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 reactions raw 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, which includes adding the precursor reactant raw materials in the solvent phase of the liquid phase to get the evenly mixed powder through ultrasonic mixer; Wherein the precursor reactant raw materials include aluminum and boron powder; The uniformly blended suspension is frozen until it sets, then the solvent is removed using vacuum freeze-drying technique to obtain treated precursor raw materials;
