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.

In the future, with the upgrading of green manufacturing and the demand for functional glass, the application of magnesium oxide will develop towards refinement: on the one hand, the mechanical and optical properties of glass will be further improved by doping with nano MgO (particle size<50 nm); On the other hand, by combining AI driven component design, a new MgO based glass system (such as MgO Li ₂ O-ZrO ₂ low melting point glass) can be developed to adapt to flexible electronics and hydrogen energy storage and transportation applications. The value of magnesium oxide in glass composition is shifting from a "performance regulator" to a "functional enabler", driving the evolution of glass materials towards higher performance and wider scenarios.

During the transportation process of powder, it is necessary to avoid stacking, as stacking can affect the fluidity of the powder. Stacking can be avoided by installing slopes, increasing transportation pipelines, and other methods.

Alpha and Gamma alumina are two of the most widely used types of alumina in various industrial applications. Though both types are derived from the same raw material, they differ in terms of properties, structures, and behaviour, making them suitable for distinct applications. In this blog post, we will explore the differences between alpha and gamma alumina and how these differences impact their functionality.

Infrared spectroscopy: It looks at how much light has been consumed. When a molecule absorbs light of a specific wavelength, we know what functional groups are inside it. Raman spectroscopy: It looks at how much light has been deflected. A laser beam is applied to analyze how much the light bounced back has changed, in order to determine the molecular structure.

Nanoparticle transmission electron microscopy (TEM) is an important microscopy technique widely used to observe and characterize the structure and morphology of nanoscale particles and materials.
