Compared with ordinary graphite powder, ultrafine graphite powder materials have the characteristics of low melting point, high chemical activity, strong magnetism, good thermal conductivity, and abnormal absorption of electromagnetic waves due to the "volume effect" and "surface effect". In recent years, ultrafine graphite powder has become a cutting-edge research field in interdisciplinary fields such as polymer chemistry, physical chemistry, inorganic chemistry, and materials science.
The smaller the particle size of ultrafine graphite powder, the more significant the physical and chemical properties change, and ultrafine graphite powder does not require additives. This opens up broader avenues for the application of high-performance inorganic structural materials. The smaller the diameter of ultrafine graphite powder particles, the larger their total specific surface area, and the corresponding increase in surface energy, resulting in higher chemical activity. This can be used as an efficient chemical catalyst in the reaction and as a combustion additive for solid rocket fuels. Our Qingdao Huatai graphite practice has shown that when ultrafine graphite particles are used as the main component to make catalysts, the efficiency is 10 times higher than that of traditional catalysts in the hydrogenation of organic matter; Adding about 1% mass of ultrafine particles to solid rocket fuel can increase the utilization rate of combustion heat per gram of fuel by about double.
The ultrafine graphite powder and asphalt can be used for the production of ultrafine graphite products through the process of mixing, rolling, grinding, cold forming, roasting, impregnation, and graphitization
