    Two major surface modification technologies and research progress of spherical silica micro powder

    Although spherical silicon micro powder is spherical and has good fluidity, there are still problems of poor compatibility and difficult dispersion when used as an inorganic filler mixed with organic matrix materials. Therefore, surface modification is necessary to solve these problems. Surface modification of spherical silicon micro powder involves introducing specific functional groups or coatin...

    Plasma spheroidization method: preparation of spherical powders focusing on ceramic materials and refractory metals

    With the rapid development of modern industry and technology, different industries have increasingly high performance requirements for powder materials. In addition to having extremely low impurity content, fine particle size, and narrow particle size distribution, powder materials also need to have a certain particle morphology. Spherical powders have been widely used in high-end industries such ...

    Transmission Electron Microscopy (TEM): Sample Requirements and Preparation Methods

    In transmission electron microscopy (TEM) analysis, the primary and crucial step in obtaining a high-quality image that can be interpreted reasonably is sample preparation. Inappropriate sample thickness, poor conductivity, or damage introduced during sample preparation can directly lead to abnormal electron beam penetration, image distortion, and even sample scrapping. TEM sample requirements ① T...

    What is the aggregation and dispersion of nanoparticles

    What are nanoparticles? Nanoparticles (NPs) are typically defined as granular materials with at least one dimension at the nanoscale (1-100 nm) in three-dimensional space. From the dimensions of structure and morphology, nanoparticles can be classified into zero dimensional nanomaterials (0D nanomaterials), corresponding to one-dimensional (1D) and two-dimensional (2D) nanomaterials. 0D nanopartic...

    How to characterize nanoparticle aggregation and dispersion?

    1.Characterization of particle size and distribution Dynamic Light Scattering (DLS): DLS is one of the most commonly used techniques for measuring the particle size and distribution of nanoparticles in suspensions. It calculates the hydrodynamic diameter of particles by measuring the time-dependent light scattering intensity fluctuations caused by Brownian motion of particles. DLS can also provide...

    Why is it difficult to detect phases below 5wt% using XRD

    XRD is an important means of characterizing phases. Strictly speaking, it can determine the existence of a certain phase, but cannot determine the absence of a certain phase, making it easier to distinguish between truth and falsehood. So, what is its detection limit? Firstly, we must emphasize that XRD analysis of elemental content is very inaccurate. If we have to say what the detection limit is...
