Global boron nitride market trend 2025-2028 Hexagonal Boron Nitride is 10 Times Stronger Than Graphene by Newsbinaa-syria

Recently, on Sinopec's annual results teleconference, the company representative answered questions about the oil prices, and said that the future trend of oil prices is still very uncertain, and it is expected to be around $100 this year and $85 next year respectively.

Sinopec, "There are many factors affecting oil prices at the moment, including geopolitics, macroeconomic trends, the implementation of the policy of OPEC+, the strength of the US DOLLAR and so on. We see a lot of uncertainty in the future oil prices. It is impossible to predict the accurate price, but a general trend could be estimated."

According to Sinopec, international institutions generally have a forecast of around $100 this year and around $85 next year in the oil prices. As geopolitical problems and other issues ease next year, oil prices will be lower than this year.

The volatile oil prices in the international market will continue to affect lots of industries and the supply of many boron nitride.

Hexagonal boron nitride (H-BN) is a two-dimensional layered broadband-gap insulating material with good heat resistance, chemical stability, and dielectric properties. It is widely used in electronic devices.

Hexagonal boron nitride is structurally similar to graphene, consisting of a planar lattice of atoms arranged in interconnected hexagons. The only difference is that in graphene, all atoms are carbon, whereas, in H-BN, each hexagon contains three nitrogen atoms and three boron atoms.

Carbon-carbon bonds are among the strongest, so graphene is theoretically much stronger than H-BN. The strength and elastic modulus of the two materials are similar, and h-BN is slightly lower in comparison: graphene has a strength of about 130GPa and young's modulus of about 1.0TPa; The strength and modulus of H-BN are 100GPa and 0.8 TPA, respectively.
Despite its excellent mechanical properties, graphene has low crack resistance, which means graphene is brittle.
In 1921, British engineer Griffiths published a theoretical study of fracture mechanics, describing the failure of brittle materials and the relationship between the size of cracks in materials and the force required to make them grow. For hundreds of years, scientists and engineers have used this theory to predict and define the toughness of materials.
In 2014, a study by Professor Jun Lou and his team at Rice University showed that graphene's fracture toughness is consistent with Griffith's theory of fracture mechanics: when the stress applied to graphene is greater than the force holding it together, the cracks propagate, And the energy difference is released during crack propagation. 
H-bn is also thought to be vulnerable, given its structural similarity to graphene. However, this is not the case.
The scientists found that H-BN is 10 times more ductile than graphene. 
A team led by Prof. Jun Lou of Rice University and Prof. Hua Jian Gao of Nanyang Technological University in Singapore has found that the brittle H-BN is 10 times stronger than graphene in cracking resistance.  This finding runs counter to Griffith's fracture theory, and such anomalies have never been observed before in two-dimensional materials.  The related research results were published in Nature with the title "Intrinsic Toughening and stable crack propagation in Hexagonal Boron nitride". 
Mechanism Behind H-BN's Extraordinary Toughness 
To find out why, the team applied stress to the H-BN sample, using scanning electron microscopes and transmission electron microscopes to see as much as possible how the cracks occurred. After more than 1,000 hours of experiments and subsequent theoretical analysis, they discovered the mystery. 

Although graphene and H-Bn may be structurally similar, boron and nitrogen atoms are not the same, so there is an asymmetric arrangement of hexagonal lattice intrinsic in H-BN, unlike the carbon hexagon in graphene. That is, in graphene, the cracks tend to go straight through the symmetrical hexagonal structure from top to bottom, opening the bond like a zipper. The hexagonal structure of H-BN is slightly asymmetric due to the stress contrast between boron and nitrogen, and this inherent asymmetry of the lattice causes cracks to bifurcate, forming branches. 
And if the crack bifurcates, that means it's rotating. The existence of this steering crack requires additional energy to further promote the crack propagation, which makes the crack more difficult to propagate and effectively enhances the toughness of the material. That's why H-Bn shows more elasticity than graphene.
Due to its excellent heat resistance, chemical stability, and dielectric properties, H-BN has become an extremely important material for two-dimensional electronic and other 2-bit devices, not only as a support base but also as an insulating layer between electronic components. Today, h-BN's toughness makes it an ideal choice for flexible electronics and is important for the development of flexible 2D materials for applications such as two-dimensional electronics.
In the future, as well as being used in flexible electronic textiles, h-BN could also be used as flexible electronic skin and implantable electronics that can be connected directly to the brain.

Chile's government has decided to create a state-owned lithium enterprise and hopes to establish a model for the company by the end of the year, Mining Minister Marcela Hernando said in an interview.  

Chile is the world's second largest lithium producer and has the largest reserves of lithium in the world. The domestic lithium industry is currently dominated by two private companies, Albemarle and SQM.  

Chile wants to participate more closely in the booming lithium market after leftist President Gabriel Boric took office in March. The accelerating electrification of the global auto industry has helped push prices of lithium, a key raw material for electric car batteries, to record highs over the past year, lapping up more players, including Mexico and Argentina, who want a piece of the market.  

According to Hernando, the government is setting up a task force to determine the best way to run state-owned lithium enterprises. She said the government hopes to establish plans by the end of the year for how the company will develop and what business model it will operate under. 

Hernando stressed that while the state would be a major shareholder in the proposed company, it was open to private investment.
