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.

Small particle alumina powder has a wide range of applications in ceramics, chemical engineering, electronics and other fields due to its unique physical and chemical properties. However, in practical applications, small-sized alumina powder is prone to agglomeration, which refers to the phenomenon of powder particles adhering to each other and forming larger aggregates during storage, transportation, or use due to various factors. Causing its performance to be affected. The agglomeration phenomenon can lead to poor flowability and reduced dispersibility of the powder, affecting product quality.

As the demand for high-quality materials in various industries continues to grow, the need for effective powder dispersion techniques and methods is becoming increasingly crucial. Powder dispersion refers to the process of mixing dry particles with a liquid medium to form a homogeneous solution or suspension. In this article, we will explore the powder dispersion techniques and methods used by SAT NANO to produce high-quality ultrafine powders

Surface hydroxyl engineering refers to the targeted regulation of the number, distribution, and chemical activity of hydroxyl (- OH) groups on the surface of materials through physical, chemical, or plasmonic means, in order to achieve precise adjustment of surface properties. Hydroxyl groups are the most common polar functional groups that can form hydrogen bonds, coordination bonds, or covalent bonds with water, metal ions, polymer chains, or biomolecules, significantly altering the hydrophilicity, surface energy, adsorption/catalytic activity, and biocompatibility of materials.

In conclusion, ultrafine powders offer an array of benefits, but their processing can be challenging. Surface coating is an effective solution for enhancing the properties of these powders, improving their performance, and extending their applicable scope. The methods discussed in this blog post- PVD, CVD, sol-gel, and polymer coatings- are just a few examples of the many surface coating options that are available for ultrafine powders. Whether you are in the pharmaceuticals, cosmetic, or electronic industry, surface coating could make the difference in the success of your product.
