Introduction to amorphous boron powder
Amorphous boron powder is a kind of material with irregular crystal form composed of boron element. Compared with the traditional crystalline boron, amorphous boron powder has higher chemical activity and wider application. The preparation and application of amorphous boron powder is an important research direction in the field of chemistry and materials science in recent years.
Preparation method of amorphous boron powder
The amorphous boron powder is prepared by chemical vapor deposition (CVD), sputtering, laser pulse, plasma and other special processes. These methods need to be carried out under high temperature and pressure, and the reaction parameters need to be precisely controlled to obtain highly active amorphous boron powder.
Among them, chemical vapor deposition and sputtering are the most commonly used preparation methods. In these processes, boron sources (such as boron trichloride, silicon tetrachloride, etc.) and hydrogen gas react at high temperatures to produce amorphous boron powder. The particle size, morphology and chemical activity of amorphous boron powder can be controlled by the precise control of reaction temperature, pressure and flow rate.
