In many fields of industrial production, powder materials are indispensable 'basic building blocks'. They are not simply 'powders' but a special material form composed of a large number of solid particles with particle sizes ranging from 0.1 nanometers to 1 millimeter. From metal powders commonly used in machine shops to ceramic powders in the new materials field, these materials play a core role in numerous industries due to their unique structural properties, serving as a crucial link between basic raw materials and end products.

The core advantages of powder materials stem from their 'granular' structure—extremely large specific surface area endows them with excellent reactivity, adsorption capacity, and forming performance, while good flowability makes them suitable for continuous production lines. Compared to bulk materials, they can easily achieve uniform component mixing; for example, alloy powders in mechanical manufacturing allow precise control of element ratios. In sintering processes, powder particles can bond tightly to form high-density finished products, reducing material waste.

Their applications have long permeated core areas such as machinery, electronics, and building materials: powder metallurgy parts in machine shops (such as gears and bearings) are made by pressing and sintering iron powder and copper powder, combining high strength with low cost. Ceramic powders are the core raw material for producing insulating devices and wear-resistant parts. In the new energy sector, ternary powders used as positive electrode materials in lithium-ion batteries directly determine the battery's
