Investigation Of Preparing Bi Nanoparticles By

When the size of semiconductor materials is reduced to nanoscale, their physical and chemical properties change drastically, resulting in unique properties due to their large surface area or quantum size effect.Currently, semiconductor nanomaterials and devices are still in the research stage, but they are promising for applications in many fields, such as solar cells, nanoscale electronic.

We are a mining equipment production and sales company, with three production bases and four research institutes, more than 600 production equipment, precision production, and service globally.
