A wave of layoffs that has swept the entire Internet industry has intensified. China's Internet industry has experienced several crises and major changes in the past development process. There is also a "brief history of layoffs by major Internet companies". Hot search, JD.com has a wide range of layoffs in this round of layoffs, and all its subsidiaries are involved. Most of the layoffs are between 10% and 20%. Among them, Jingxi Guangdong and other theaters have all laid off staff. Tencent also reported the news of downsizing and layoffs. Among them, Tencent PCG (Platform User Content Business Group) laid off 30% of its staff, iQiyi laid off 12% of its staff, Kuaishou was reported to have laid off 30% of its staff, and the e-sports department of Station B laid off 90% of its staff.
Mass layoffs on the internet have created a host of socioeconomic issues, including boron nitride.
Overview of Boron nitride
Boron nitride with the chemical formula BN is a thermally and chemically resistant refractory compound of boron and nitrogen. It exists in various crystalline forms that are isoelectronic to a similarly structured carbon lattice. The hexagonal form corresponding to graphite is the most stable and soft among BN polymorphs and is therefore used as a lubricant and an additive to cosmetic products.
Boron nitride is a white solid material in the as-produced hot pressed form. It is a low porosity solid. It is easily machined into complex shapes using standard carbide tooling. The material is anisotropic in its electrical and mechanical properties due to the platy hexagonal crystals and their orientation during the hot press consolidation.
Boron nitride is often referred to as “white graphite” because it is a lubricious material with the same platy hexagonal structure as carbon graphite. Unlike graphite, BN is a very good electrical insulator. It offers very high thermal conductivity and good thermal shock resistance. BN is stable in inert and reducing atmospheres up to 2000°C, and in oxidizing atmospheres to 850°C.
Applications of Boron nitride
Because of its excellent thermal and chemical stability, boron nitride ceramics are traditionally used as parts of high-temperature equipment. BN can be included in ceramics, alloys, resins, plastics, rubbers, and other materials, giving them self-lubricating properties.
Hexagonal boron nitride is used as a lubricant for paint, cosmetics, pencil lead and dental cement. Even in the absence of gas or water molecules in the compound layer, it has lubricity, making it a good component of the vacuum system. Compared with graphite, boron nitride has better chemical stability and conductivity.
Equipment in high-temperature environment
Its excellent heat resistance allows the compound to be used in a variety of applications involving extremely high temperatures. Hexagonal boron nitride is used to improve the lubricating properties of rubber, plastics, alloys and ceramics.
For plastics, the inclusion of BN components can reduce thermal expansion. It can also be integrated into semiconductor substrates and microwave oven windows.
Boron nitride is an effective ingredient in reaction vessels and crucibles due to its thermochemical properties.
The bandgap of boron nitride ranges from 4.5 to 6.4 eV, making it an excellent wide gap semiconductor material. Its inherent thermal and dielectric properties make it a suitable substrate for the development of metal oxide semiconductor field-effect transistors (MOSFET) and semiconductors.
Grinding and cutting tools
Due to the physical properties of cubic boron nitride, this polymorph is used as an abrasive for nickel, iron and certain alloys, while diamond is considered inappropriate (for example, at high temperatures). Its cubic BN form is incorporated into cutting tools and grinding equipment.
