Enthusiasm for research on new aerogels increases, and the development and application process of nitride aerogels will be accelerated

Aerogel is a nano-scale porous solid material. Depending on the matrix, aerogel can be divided into inorganic aerogel, organic aerogel, mixed aerogel and composite aerogel. Inorganic aerogel is further divided into Oxide aerogel, nitride aerogel, fluoride aerogel, etc. Nitride aerogel is a new type of inorganic aerogel, and its subdivided products include Si3N4 aerogel, boron nitride (BN) aerogel, C3N4 aerogel, vanadium nitride aerogel, etc.

As a porous material, aerogel has excellent properties and is one of the current hot spots in materials science research. There are many types of aerogels. In recent years, with the continuous deepening of research and the vigorous development of materials science, nitride aerogels, clay aerogels, metal nanowire aerogels, graphene aerogels, etc. have special structures and properties. New types of aerogels are emerging one after another. While the types of aerogels are abundant, their performance has also been greatly improved.

Nitride aerogel has the dual characteristics of aerogel and nitride. Compared with ordinary aerogel, nitride aerogel has a wider application space. However, as a new aerogel material, the research, application and promotion of nitride aerogels at home and abroad are still in the basic stage. According to the “2022-2026 China Nitride Airgel Industry Market Monitoring and Future Development Prospects Research Report released by the Industrial Research Center ” shows that the current research on nitride aerogels is mainly focused on Si3N4 aerogels and BN aerogels. In China, nitride aerogel-related R&D institutions or enterprises include Xi’an Jiaotong University, Inner Mongolia Haite Huacai Technology, and National Nano Center, Chinese Academy of Sciences, etc.

Compared with the European and American markets, my country’s aerogel market started late, and there are still certain gaps in material research and development, production, application and market development. In order to promote the localization, high-end, and new development of aerogels, our government has issued a number of favorable policies in recent years, including the “Announcement of the Central Committee of the Communist Party of China and the State Council on Completely, Accurately and Comprehensively Implementing the New Development Concept and Doing a Good Job in Carbon Neutralization at the Peak.” The Opinions clearly mentioned that it is necessary to accelerate the research and development and application of new materials such as aerogels. Under the guidance of policies, the research and development and application process of nitride aerogels in my country will be accelerated.

Nitride aerogels have excellent properties and broad application prospects. For example, Si3N4 aerogel has the dual characteristics of Si3N4 ceramic and aerogel, and has broad application prospects in thermal insulation and thermal insulation function integration; BN aerogel has high thermal conductivity and electrical insulation, and is widely used in lubricants, refractory materials, and heat dissipation components. , huge application potential in insulation materials.

Industry analysts said that at present, the research and application of nitride aerogels at home and abroad are still in the basic stage. However, in the new era, the market is paying more and more attention to the application of new materials, new technologies, and new concepts. The enthusiasm and depth of research on new aerogels at home and abroad will continue to rise. Nitride aerogels are a new type of inorganic aerogels. One of the glues will also receive wider attention.
