Global h-BN powder market trend 2022-2028 How Do You Make a Hexagonal Boron Nitride? by Newsb-house

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, 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 h-BN powder.

Boron nitride is a crystal composed of nitrogen atoms and boron atoms, with a chemical composition of 43.6% boron and 56.4% nitrogen.


It has four different variants:

hexagonal boron nitride (HBN),

rhombohedral boron nitride (RBN),

cubic boron nitride (CBN),

wurtzite boron nitride (WBN).


How Do You Make a Hexagonal Boron Nitride?

Hexagonal boron nitride is obtained by the reaction of boron trioxide (B2O3) or boric acid (H3BO3) with ammonia (NH3) or urea (CO (NH2) 2) in nitrogen atmosphere:

B2O3 + 2NH3 2BN + 3H2O (T = 900C).

B (OH) 3 + NH3 BN + 3H2O (T = 900C).

B2O3 + CO (NH2) 2 "2BN + CO2 + 2H2O (T > 1000 °C).

B2O3 + 3CaB6 + 10N2 20BN + 3CaO (T > 1500 °C).

The resulting disordered (amorphous) boron nitride contains 92-95% BN and 5-8% B2O3. The remaining B2O3 can be evaporated at a temperature of > 1500 °C in the second step to achieve a BN concentration of > 98%. This kind of annealing also makes BN crystallize, and the size of microcrystals increases with the increase of annealing temperature.


What is Wurtzite Boron Nitride Used For?

Wurtzite boron nitride has two different particle shapes: plate crystal type and regular crystal type.

Using wurtzite boron nitride with flake particles as raw material, coarse-grained polycrystalline powder was sintered, which was used to make traditional cutting tools and grinding tools. The cutting teeth made of wurtzite boron nitride material have excellent impact resistance, which is better than that of conventional polycrystal CBN.

Wurtzite boron nitride with regular crystal shape particles is an ideal material for steel polishing, such as moulds, moulds and so on.


Why is Hexagonal Boron Nitride an Insulator?

Hexagonal boron nitride has good electrical insulation, thermal conductivity, chemical corrosion resistance and lubricity, and has a strong neutron absorption capacity, which is relatively stable for almost all organic solvents and corrosive chemicals. It is chemically inert to almost all molten metals. Below 1000 in the air, all kinds of physical and chemical properties remain basically unchanged. The temperature used in nitrogen or argon is still stable at 3000 .


How Hard is Wurtzite Boron Nitride?

A certain amount of information has been reported about cBN, especially its hardness, about 45-50GPa. However, almost nothing is known about the mechanical properties of wBN.

WBN is also a kind of superhard material whose hardness is close to diamond, and its hardness varies greatly from 24GPa to 54GPa. However, wurtzite boron nitride is a high-pressure metastable phase, which can be easily converted to hexagonal boron nitride (with a structure similar to graphite) at atmospheric pressure, and micron wurtzite boron nitride can only be prepared by shock wave compression. It is important to know that wurtzite boron nitride can be converted into cubic boron nitride under the conditions of ultra-high temperature and high pressure exceeding 6gpa and 1400 °C.


How Much does Boron Nitride Cost?

The price is influenced by many factors including the supply and demand in the market, industry trends, economic activity, market sentiment, and unexpected events.

Gas supplies have been in short supply because of the conflict between Russia and Ukraine.  Combined with the situation that other renewable sources cannot produce enough electricity, electricity prices have soared in many parts all over the world. For this reason, I assume the supply and prices of the h-BN powder would keep being influenced by the high energy prices.
