Among the numerous ingredients in sunscreen cosmetics, nano zinc oxide stands out as the core component of physical sunscreen, which is not accidental. Nano zinc oxide, in simple terms, refers to zinc oxide with a particle size in the nanometer range, typically between 1-100 nanometers. This tiny particle size endows it with many unique properties, making it outstanding in the field of sun protection.
In the current era of miniaturization of electronic devices, rapid development of the new energy industry, and continuous improvement of LED lighting power, "heat dissipation" has become a core bottleneck restricting product performance upgrades and lifespan extensions. Traditional thermal conductive materials either have insufficient thermal conductivity efficiency, poor compatibility, and are prone to settling, making it difficult to meet the needs of high demand scenarios. Nano aluminum oxide, with its unique nanoscale structure and excellent thermal conductivity, is becoming a "performance breakthrough" in the field of thermal conductivity, providing efficient heat dissipation solutions for multiple industries such as electronics, new energy, and lighting.
The reason why nano copper oxide can excel in many fields is due to its unique properties. It has a small particle size and high activity, and exhibits excellent performance in magnetism, light absorption, thermal resistance, catalysts, and other aspects, laying a solid foundation for its application in multiple fields. Now, let's delve into its outstanding performance in different fields!

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.
