The crystal structure of nano iron oxide is hexagonal, and the lattice parameters change with the decrease of particle size. When the particle size is large (usually larger than tens of nanometers), iron oxide exhibits a typical α- The Fe2O3 structure, also known as hematite structure, is red in color. This is because typical α- The Fe2O3 structure has a high reflectivity for visible light, absorbing shorter wavelengths (blue-green) in visible light, leaving only longer red wavelengths observed.

50nm zirconium dioxide nanopowder is a high-purity, white crystalline powder composed of tiny zirconium dioxide particles, each measuring 50nm in diameter. During the production, we employ advanced technology to ensure that the particles are uniformly sized and dispersed, resulting in a stable and reliable nanopowder that has excellent performance and consistency.

Scanning Electron Microscope (SEM) is a high-resolution characterization and analysis technique that uses a focused electron beam to scan the surface of a sample point by point, excite secondary electron SE, backscattered electron BSE, characteristic X-rays and other signals, and image them, thereby achieving the microstructure, chemical composition and microstructure of the sample surface. This article will briefly introduce common problems in the SEM testing process, their causes, and corresponding solutions:

the development of Van der Waals welding for carbon nanotubes represents a significant advancement towards harnessing the exceptional mechanical properties of CNTs on a macroscopic scale. With further refinement and optimization, this innovative welding method has the potential to revolutionize the manufacturing of high-performance materials, driving progress in fields requiring lightweight, durable, and strong structural components. As researchers continue to push the boundaries of nanotechnology, the future looks promising for the widespread adoption of carbon nanotubes in industrial applications.

There are several techniques that can be used to test the purity of a powder. One common method is X-ray diffraction analysis (XRD), which can be used to identify and quantify the different crystalline phases in a powder.

Titanium dioxide is mainly divided into three types: plate titanium dioxide, anatase titanium dioxide, and rutile titanium dioxide. Rutile titanium dioxide and anatase titanium dioxide are two important types of titanium dioxide, which are currently the most widely used in the market. However, their properties differ greatly.
