Silicon nitride nanowires have broad application prospects, and silicon nitride nanowire aerogels are their end products.

Silicon nitride nanowires are one-dimensional nanostructures of silicon nitride materials. Compared with other forms of silicon nitride products such as silicon nitride powder and silicon nitride bulk, silicon nitride nanowires have good chemical stability, good high temperature resistance, good flexibility, corrosion resistance, and good optoelectronic properties. Advantages, widely used in optical nanodevices, solar energy conversion devices, electronic and electrical fields, etc.

Preparation methods of silicon nitride nanowires include precursor cracking method, direct nitridation method, template method, carbothermal reduction method, etc. The precursor cracking method is derived from the precursor conversion method. It uses polycarbosilane as the precursor, and then undergoes high-temperature cracking, nitrogen synthesis and other processes to produce silicon nitride nanowires. This method is expected to become the mainstream of silicon nitride nanowires in the future. Preparation method; direct nitridation method is a traditional preparation method of silicon nitride nanowires. This method uses silicon dioxide or silicon powder as the core raw material, and then introduces nitrogen or ammonia gas to synthesize silicon nitride nanowires after full reaction. This method It has the advantages of simple production process and low operating cost.

Silicon nitride nanowire aerogel, silicon nitride nanowire refractory paper, etc. are silicon nitride nanowire end products.
