Nano-indium powder is produced by a variable current laser ion beam gas phase method. It has high purity, uniform particle size, easy dispersion, and high surface activity. It can be used for semiconductors, high-purity alloys and back-field aluminum pastes of silicon solar cells (silver paste, aluminum paste, etc.) , Antistatic materials, etc.; nano indium powder can be used as an additive for antistatic transparent coatings and surface materials; nano indium powder has antistatic, transparent and resistance to friction and scratches. It is a new generation of electronic packaging materials and flat panel displays. Ideal additive materials for platforms and clean room surface materials; nano-indium materials also have electrical conductivity, which also makes them the raw materials for future photovoltaic cells (solar cells), medical devices, and biotechnology imaging products.
