Since 2022, Russia-Ukraine geopolitical conflicts have intensified, and global energy prices have risen sharply, with international natural gas prices hitting historic highs. As the most important transitional energy source in the transition from fossil energy to non-fossil energy, the share of natural gas in primary energy has increased from 14.6% in 1965 to 24.7% in 2020. The global gas price indices showed a unilateral downward trend from 2018, bottomed out in 2020, and remained low for a long time. However, since July 2020, the global gas prices have gradually fluctuated upward, and the impact of geopolitical events made the Dutch TTF gas price even hit record highs repeatedly.
An analyst of a securities company believes that the core catalyst of this round of global gas market lies in the lack of investment in upstream oil and gas resources caused by long-term low prices. Since 2020, although the epidemic has led to a decline in demand, the decline in supply has been faster, resulting in a large inventory consumption. In 2021, demand will recover faster than supply (the supply-side is less sensitive to prices, which will be reflected in investment).
As the world's two largest gas h-BN powder are also expected to change significantly.
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.

New Delhi: India is seeking to increase its purchases of crude oil from Brazil, the country's oil minister said recently after meeting his Brazilian counterpart.
India is the world's third-largest importer and consumer of crude oil. Brazil currently supplies only a fraction of India's crude oil imports.
India's state-owned companies Bharat Petroleum Corp and Oil and Natural Gas Corp have invested in oil and gas exploration in Brazil.
India, which imports about 84% of its crude oil needs, is reducing its import bill by increasing biofuel use, among other things.
India's state-owned fuel retailers are increasing ethanol storage capacity by 51 percent and the country plans to double the biofuel blend in petrol to 20 percent by 2025.
India and Brazil are currently cooperating on biofuels and ethanol.
The prices of many commodities like the h-BN powder are expected to increase in the future.
