Boron nitride nanotubes (BNTS) are a new type of nanomaterial with excellent mechanical and electrical properties and have wide application prospects. Its synthesis technology is one of the key research directions, the main points of synthesis technology include material selection, synthesis method, control parameters and so on.

Firstly, the selection of suitable raw materials is the first step in the synthesis of boron nitride nanotubes. Boric acid, borane and nitrogen are usually used as raw materials to prepare boron nitride nanotubes by chemical vapor deposition or pyrolysis. Raw material selection factors such as the ratio of boron and nitrogen, the concentration of reaction gas and the flow rate play an important role in the synthesis of boron nitride nanotubes.

Secondly, the synthesis method is also an important factor affecting the quality of boron nitride nanotubes. At present, the common synthesis methods include chemical vapor deposition, pyrolysis, arc discharge and so on. Different synthesis methods have their own advantages and disadvantages, it is necessary to choose the appropriate method according to the specific requirements.

In addition, controlling the synthesis parameters is also the key to the synthesis of boron nitride nanotubes. Such as the adjustment of reaction temperature, pressure, time and other parameters have a great influence on the morphology, structure and properties of boron nitride nanotubes. Therefore, these parameters need to be precisely controlled during the synthesis process to achieve the desired boron nitride nanotube properties.

In general, the main points of the synthesis technology of boron nitride nanotubes include material selection, synthesis method and control parameters. By optimizing these points, the precise control of boron nitride nanotubes can be achieved, and its quality and performance can be improved, which lays a foundation for its application in electronic devices, catalysts, sensors and other fields. It is hoped that the synthesis technology of boron nitride nanotubes can be further studied in the future to promote its wide application in various fields.
