​Quantum dots (QDs) refer to semiconductor nanoparticles with a size smaller than the Bohr radius of the exciton and exhibiting quantum confinement effects. Due to the quantum confinement effect, the fluorescence emission of quantum dots is related to their diameter and chemical composition. By compounding with semiconductor surfaces, their optical and photochemical properties can be enhanced. Traditional quantum dots are mostly composed of heavy metal elements. Although their excellent performance has been widely used in fields such as biological imaging, electrochemistry, and energy conversion, heavy metal elements can cause environmental pollution and affect the health of organisms.

SAT NANO has recently completed an export order — shipping 2KG of high-purity Titanium Nitride (TiN) powder to a Japanese client. This marks another milestone in SAT NANO's continued expansion across the Asia-Pacific advanced materials market.

Q1: Do you accept sample order? A: Yes, we accept small order from 10g, 100g, and 1kg for your evaluation quality of our goods.

Spherical silica micro powder has excellent properties such as high transparency, high dielectric, high moisture resistance, high filling amount, low expansion, low stress, and low friction coefficient. It is widely used in many fields such as epoxy molding materials, catalysts, copper clad panels, adhesives, and aerospace.

At just a fraction of the size of traditional copper powders, our nano metal copper powder boasts an incredibly high surface area-to-volume ratio, which makes it an ideal choice for a variety of industrial and technological applications.

As one of the most important characterization parameters of nano powder, particle size directly affects the physical and chemical properties of the powder, and then affects the performance of the final product. Therefore, its detection technology is an important tool for industrial production and quality management, and plays an irreplaceable role in improving product quality, reducing production costs, and ensuring product safety and effectiveness. This article will start from the principle and compare three common methods for powder particle size detection: electron microscopy, laser particle size analysis, and X-ray diffraction line width method, and analyze the advantages, disadvantages, and applicability of different particle size testing methods.
