超微粉末粉砕プロセスと装置の選び方
Ultrafine powder milling technology is called a cross-century high-tech by scientists worldwide. After refinement, material properties change significantly. Optical, electrical, magnetic, and mechanical properties are affected. Thermal, surface, and interface characteristics also change. Extraordinary effects are often achieved in use. Ultrafine powder milling is usually divided into micron-grade, submicron-grade and nano-grade powders. The international scientific community usually calls ultrafine powders with a particle size greater than 1μm micron-grade powders. Powders with a particle size of 0.1-1μm (i.e. 100nm-1000nm) are called submicron-grade powders. Powders with a particle size of 0.001-0.1μm (i.e. 1nm-100nm) are called nano-grade powders (also known as nanomaterials). In a broad sense, nanomaterials refer to materials with at least […]
