The difference in cohesive force between different powders is due to the type and strength of interparticle forces (van der Waals forces, capillary forces, electrostatic forces, etc.), and its core influencing factors include particle size, surface roughness, moisture content, and material properties, resulting in cohesive force that can span multiple orders of magnitude (from 10 ⁻⁶ N to 10 ⁻¹ N). This difference can be quantitatively described through the aggregation feature index, surface tension, and roughness correction model.
Ceramic particles have a wide range of applications in materials science, electronics, chemical engineering, medical and other fields, but due to their high surface energy and easy aggregation characteristics, dispersion has always been a key challenge in preparing high-performance ceramic materials. This article will introduce common types of ceramic particles and recommend suitable dispersants for different ceramic materials to improve dispersion stability and processing performance.
ATO Dispersion plays a critical role in modern transparent conductive materials, thermal insulation coatings, and antistatic applications. In this in-depth guide, SAT NANO explains what ATO Dispersion is, how it works, where it is used, and why it has become an indispensable material for high-performance industrial formulations.
A particle refers to the smallest independent and discrete unit formed by the nucleation and growth of substances in a specific reaction system (such as combustion, precipitation, gas-phase synthesis, etc.), with regular or irregular geometric shapes. It can be understood as the most fundamental individual that is "innate" in the process of material formation.
As someone deeply involved in materials science, I’ve seen firsthand how the right components can transform performance. One of the most exciting advancements we’ve integrated at SAT NANO involves Tin Dioxide Nanoparticles.
Hydroxyl groups (- OH) can exhibit acidity or alkalinity on the surface of metal oxides in the form of proton reception or supply. By adjusting the quantity and distribution of hydroxyl groups, precise control of surface acidity and alkalinity can be achieved, thereby affecting the activation pathway and selectivity of catalytic reactions.
