In the new energy vehicle industry, the application of various advanced materials is the foundation that supports the entire industry. In this article, we will explore the increasingly important role of ceramics in the intelligentization process of new energy vehicles.

Ceramic metallization refers to firmly adhering a thin layer of metal film to the ceramic surface to achieve welding between ceramic and metal. There are various ceramic metallization processes, including molybdenum-manganese method, gold plating method, copper plating method, tin plating method, nickel plating method, and LAP method (laser-assisted plating).

There are many types of ceramic bearings available that offer numerous advantages over traditional bearing components. Two common ceramic materials used for bearing applications are silicon nitride (Si3N4) and zirconia (ZrO2).

Hexagonal boron nitride (h-BN) is a crystalline structure composed of nitrogen and boron atoms arranged in a hexagonal lattice. It is the only phase of boron nitride that exists naturally in the environment. It appears as a soft, loose, smooth, and moisture-absorbing white powder, and it shares similar layered structure characteristics with graphene, earning it the nickname "white graphite."

Direct Bond Copper (DBC) ceramic substrate has become an important electronic packaging material due to its excellent thermal conductivity and electrical conductivity, especially in power modules (IGBT) and integrated power electronic modules.

Alumina ceramic is the most commonly used ceramic substrate material, favored for its overall good performance. The advantages of alumina ceramic substrates include excellent insulation performance, exceptional high-temperature resistance, high strength and hardness, outstanding chemical stability, and good processability.

The application of boron nitride ceramic in horizontal continuous casting is mainly for the use of break rings and crystallizers.

Precision ceramics find applications in various processes in semiconductor manufacturing, including lithography, etching, deposition, chemical mechanical polishing (CMP), ion implantation, and wire bonding. Through their exceptional performance and properties, precision ceramic components ensure stability, high precision, and reliability in semiconductor manufacturing processes.

The two main application directions of silicon nitride ceramics in the field of new energy vehicles are silicon nitride bearings and high thermal conductivity silicon nitride substrates.

Powder metallurgy and 3D printing are rapidly advancing fields, and boron nitride ceramic nozzles are emerging as noteworthy applications in these domains.
