​Metal nanopowder is an innovative material with a wide range of applications in various industries. As one of the leading manufacturers of high-quality metal nanopowders, SAT NANO is committed to providing the best products to our customers. In this article, we will explore the question of why metal nanopowder appears black.

The principle of thermochromism mainly adjusts the input of solar radiation (wavelength concentrated in 190-3000nm) energy and the output of blackbody energy through windows based on the ambient temperature. Thermochromic materials will change their transparency, absorbance, and color when the temperature changes. Thermochromic can be used as a passive design strategy to adjust near-infrared transmittance while maintaining visible light transmittance, without the need for external energy or manual operation. Therefore, thermochromic smart windows have become a hot research topic in building energy-saving windows due to their simple structure and broad application prospects.

Silver copper alloy powder is an alloy composed of two metals, silver and copper. The powder is usually gray white, with higher hardness and strength, as well as excellent conductivity and thermal conductivity, as well as good chemical stability.

The gold price has hit a high of 720 RMB per gram, as international gold prices continue to rise. This surge in gold price has led to increased demand for high-quality gold products, such as nanoscale gold powder. SAT NANO, a leading provider of nanomaterial products, offers the perfect solution with its nanoscale gold powder, which is 20-30 nanometers in size and has a purity of 99.99%.

​Copper nanoparticles have attracted a lot of interest in recent years due to their interesting properties, low-cost preparation, and many potential applications in catalysis, cooling fluids, or conductive inks. In this study, copper nanoparticles were synthesized by chemical reduction of copper sulfate CuSO4 and sodium borohydride NaBH ₄ in water without inert gas protection.

Fisher's particle size is a method used to measure the particle size of granular materials, usually determined by measuring the settling velocity of particles in air or liquid. The principle of Fisher's particle size measurement is based on Stokes' law, which means that the force exerted on small particles in the medium is proportional to their diameter. The average diameter or particle size distribution of granular materials can be obtained using the Fisher particle size test.
