Nano materials can be roughly divided into four categories: nano powder, nano fiber, nano film and nano block. Among them, nano powder has a long development time and mature technology, which is the basis for the production of other three types of products.

1. Nano powder

Also known as ultra-fine powder or ultra-fine powder, it generally refers to powder or particles with a particle size of less than 100 nm. It is a solid particle material in an intermediate state between atoms, molecules and macro objects. Can be used for: high density magnetic recording materials; Absorbing stealth material; Magnetic fluid materials; Radiation protection materials; Polishing materials for monocrystalline silicon and precision optical devices; Microchip thermal conductive substrate and wiring material; Microelectronic packaging materials; Optoelectronic materials; Advanced battery electrode materials; Solar cell materials; High efficiency catalyst; High efficiency combustion supporting agent; Sensitive element; High toughness ceramic materials (unbreakable ceramics, used for ceramic engines, etc.); Human body repair materials; Preparations, etc.

2. Nanofibers

It refers to linear materials with nanometer diameter and large length. It can be used in: micro wire and micro optical fiber (important components of future quantum computer and photonic computer); New laser or light emitting diode materials, etc.

3. Nano film

Nanofilms can be divided into granular films and dense films. Granular film is a film in which nano material particles stick together with a very small gap in the middle. Dense film refers to the film with dense film layer but nano grain size. Can be used in: gas catalysis (such as automobile exhaust treatment) materials; Filter material; High density magnetic recording material; Photosensitive materials; Flat panel display materials; Superconducting materials, etc.

4. Nano block

It is a nano grain material obtained by high-pressure forming of nano powder or controlling metal liquid crystallization. Main uses: ultra high strength materials; Intelligent metal materials, etc.
