With the adoption of silicon carbide (SiC) by Tesla in 2018 and gallium nitride by Xiaomi in 2020, the third-generation semiconductor has finally gained market recognition and ushered in development opportunities after 30 or 40 years of development.

Graphite can be divided into two categories: natural graphite and artificial graphite.

Flake graphite is a natural crystalline graphite, which is shaped like fish phosphorus, belongs to the hexagonal crystal system, and has a layered structure.

Zirconium boride includes zirconium monobboride, zirconium diboride, and zirconium lauraboride.

Zirconium nitride (ZrN) is an inorganic compound. Golden crystal powder. The density is 7.09. Insoluble in water, slightly soluble in inorganic acids, soluble in concentrated sulfuric acid, hydrofluoric acid, and aqua regia.

When it comes to display technology, in addition to the traditional LCD and LED liquid crystal display screen, OLED (organic light emitting diode) display technology has become a new mainstream.

Tantalum has excellent chemical properties and high corrosion resistance, and does not react to hydrochloric acid, concentrated nitric acid and "aqua regia", whether under hot or cold conditions.

Carbon nanotubes can be regarded as rolled graphene sheets, so according to the number of graphene sheets, they can be divided into: single-walled carbon nanotubes (or single-walled carbon nanotubes, Single-walled Carbon nanotubes, SWCNTs) and Multi-walled carbon nanotubes (or multi-walled carbon nanotubes, MWCNTs)
