What are the Key Technological Challenges of Ultrafine Powders?
Ultrafine powders refer to materials with particle sizes ranging from the micron to the nanometer scale. According to the consensus in mineral processing industry, ultrafine powders are defined as powders with 100% particle size less than 30 μm. Nanomaterials have unique properties that traditional materials do not possess, such as size effects, macroscopic quantum tunneling […]
