​The surface modification of silicon nitride powder is mainly achieved through physical and chemical methods to improve the physical and chemical properties of silicon nitride particles.

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.

In our modern world, pollutant emission and contamination in the environment are rapidly increasing, which has led to a surge in the use of nanoporous adsorbent materials. These materials are essential in adsorbing gases, waste, metals, and organic compounds. In this article, we will explore the most commonly used nanoporous adsorbent materials.

The 16th China International Powder Metallurgy & Hard Alloy Exhibition, also known as PM CHINA, is the flagship event of the global powder metallurgy industry. Since its establishment in 2008, it has grown at an astonishing rate of 30% annually, from a few hundred square meters to a massive 40,000 square meters in 2023. With its extensive international reputation and global influence, PM CHINA has become a must-attend event for companies worldwide.

Nano-aluminum oxide is a widely used material, especially in the field of nanotechnology, due to its unique physicochemical properties such as high surface area, high thermal stability, and excellent catalytic activity. However, the surface properties of nano-aluminum oxide play an important role in its performance in many applications. Therefore, surface modification of nano-aluminum oxide is essential to improve its properties for specific applications. In this article, we discuss one of the effective surface modification methods of nano-aluminum oxide, which involves using a silane coupling agent (KH-560).

Let's use an example to illustrate how to dilute the nano silver dispersion: Assuming you have a sample containing a nano silver dispersion with a concentration of 100 mg/mL, you would like to dilute it to 10 mg/mL. You are preparing to use deionized water as a diluent solvent.
