The Biden administration plans to ease sanctions on Venezuelan oil to allow more of the country's crude to reach Europe.
The U.S. will allow European companies still operating in Venezuela to immediately transfer more oil to the continent, while allowing Chevron to negotiate a resumption of operations in Venezuela, according to people familiar with the matter. Venezuela's OPPOSITION, which is backed by the United States, is understood to favor the move. Tight global oil supplies have sent crude and fuel costs soaring, threatening to add to already high inflation. Increasing Venezuelan crude exports would help ease supply constraints while also helping to reduce Europe's dependence on Russian energy.
The US has sought to encourage talks between the Venezuelan government and the US-backed opposition to open the way to free and fair elections by extending a limited license held by Chevron to allow the oil company to maintain its operations in Venezuela and negotiate future operations.
The United States reportedly did not extend a permit to Allow Chevron to drill and sell Venezuelan crude, as the company had hoped.
The license extension will allow Chevron to negotiate with State-run Petroleos de Venezuela SA, with which it has a joint venture. Previously, the company could not directly negotiate with any officials sanctioned by the United States. Chevron has been lobbying the United States to allow it to drill for Venezuelan crude and sell it on world markets to help lower energy prices amid the Russia-Ukraine war.
Affected by the ever-changing international situation, the supply and prices of many commodities like the Silicon Boride SiB6 Powder,Silicon Boride SiB6 Powder Overview,Silicon Boride SiB6 Powder Applications,Silicon Boride SiB6 Powder Price,Silicon Boride SiB6 Powder Supplier are still very uncertain.
Silicon Boride SiB6 Powder Overview
Silicon boride (also known as borosilicide) is a lightweight ceramic compound composed of silicon and boron. There are silicon triboride, silicon tetraboride, silicon hexaboride and so on.
Silicon hexaboride or hexaborosilicide is a glossy black-grey powder. The chemical formula is SiB6. The molecular weight is 92.95. The relative density is 2.47 g/cm3 and the melting point is 2200℃. The hardness is between diamond and ruby. Silicon hexaboride can conduct electricity. It is insoluble in water. Surfaces are oxidized when heated in chlorine and water vapor.
The SiB6 crystal structure consists of interconnected icosahedrons (polyhedra with 20 faces), icosahedrons (polyhedra with 26 faces), and isolated silicon and boron atoms.
It is insoluble in water and resists oxidation, thermal shock and chemical attack. Especially under thermal shock, it has high strength and stability. The grinding efficiency is higher than that of boron carbide.
Surface oxidation occurs when SiB6 is heated in air or oxygen and attacked at high temperatures by boiling sulfuric acid and fluorine, chlorine and bromine. Borides are conductive. Hexaborides have low thermal expansion coefficients and high thermal neutron cross sections.
Silicon Boride SiB6 Powder Applications
Silicon boride SiB6 powder can be used as a variety of standard abrasives for grinding carbide. It is also used as engineering ceramic materials, sandblasting nozzles, manufacturing gas engine blades and other special-shaped sintered parts and seals. Used as an antioxidant for refractory materials.
