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 HfB2 Powder.
Introduction to Hafnium Diboride HfB2 Powder
Hafnium diboride or HfB2 belongs to ultra-high temperature ceramics and is a ceramic composed of hafnium and boron.
Physicochemical Properties of Hafnium Diboride HfB2 Powder
HfB2 has a melting temperature of about 3,250 °C. It is an unusual ceramic with relatively high thermal and electrical conductivity, sharing the same properties as titanium and zirconium diboride of the same structure. It is a gray metal appearance material. Hafnium diboride has a hexagonal crystal structure with a molar mass of 200.11g/mol and a density of about 10.5g/cm3.
Hafnium diboride is usually combined with carbon, boron, silicon, silicon carbide, and nickel to improve the consolidation (sintering) of hafnium diboride powders. It usually forms a solid through a process called hot pressing, in which heat and pressure are used to press the powder together.

|Other Names||hafnium boride, HfB2 powder|
|Melting Point||3250 °C|
|Solubility in H2O||N/A|
Applications of Hafnium Diboride HfB2 Powder
Due to its strength and thermal properties, hafnium diboride has potential for use in ultra-high-speed reentry aircraft, such as heat shields for intercontinental ballistic missiles or aerodynamic fronts. Unlike polymers and composites, HfB2 forms aerodynamic shapes and does not melt during reentry.
Hafnium diboride is also being studied as a possible new material for nuclear reactor control rods. It is also being studied as a diffusion barrier for microchips. If the synthesis is correct, the barrier thickness can be less than 7 nm.
Boron (atomic symbol: B, atomic number: 5) is a p-block element of group 13 of Period 2, with an atomic weight of 10.81. Each boron layer has 2,3 electrons, and its electron configuration is [He] 2s2, 2p1. The boron atom has a radius of 90pm, and the van der Waals radius is 192pm.
Boron is classified as a metal-like substance that does not naturally occur on Earth. The element boron, along with carbon and nitrogen, is one of the few elements in the periodic table known to form stable triple bond compounds. The bandgap of boron ranges from 1.50 to 1.56 eV, which is higher than that of silicon and germanium.
Hafnium (atomic symbol Hf, atomic number 72) is an element of unit D, group 4, of Period 6, with an atomic weight of 178.49. Bohr model of hafnium the number of electrons in each layer of hafnium is 2,8,18,32,10,2 and the electron configuration is [Xe] 4f14 5d2 6s2. The hafnium atom has a radius of 159pm and the van der Waals radius is 212pm.
Hafnium was predicted by Dmitri Mendeleev in 1869, but was not isolated for the first time until 1922. In its elemental form, hafnium has a lustrous silver-gray appearance. The element hafnium does not exist in nature as a free element. It is found in zirconium compounds such as zircon. Hafnium is commonly a component of superalloys and circuits used in semiconductor device manufacturing.

As the duration of the conflict between Russia and Ukraine grows, its impact on commodities is widening amid the tug-of-war. Recently, European and American sanctions against Russia have been issued one after another. In response, Russia has taken advantage of its role as an important supplier of many energy and commodities, requiring exports of commodities, including energy, grain, metal, and wood, to "unfriendly" countries to be settled in robles. Therefore, it is expected that the price of the HfB2 Powder will continue to increase.
