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 Zirconium Carbide ZrC, Zirconium Carbide ZrC Overview, Zirconium Carbide ZrC Application, Zirconium Carbide ZrC Suppliers, Zirconium Carbide ZrC Price are still very uncertain.
Zirconium carbide ZrC powder overview
Zirconium carbide (ZrC) ceramic material has high melting point, high hardness, excellent mechanical properties, high electrical conductivity (heat) rate and excellent anti-oxidative ablation performance. As one of the ultra-high temperature ceramic material systems, it can be used as heating material ZrC ceramics The lattice structure of the material is a tight cubic lattice composed of Zr atoms, and C atoms are located on the leading edge of the space shuttle's wing, supersonic scramjet, etc. lattice. Therefore, the crystal structure of ZrC ceramic material belongs to the typical NaCl face-centered cubic structure. The lattice constant of ZrC is A=0.46930nm, and the atomic radius ratio of C to Zr is 0.481.
Is zirconium carbide ZrC a ceramic?
Zirconium carbide is a very hard refractory ceramic material.
It has high corrosion resistance. Such IV-interstitial transition metal carbides are also members of ultra-high temperature ceramics or UHTCs. Strong covalent Zr-C bonds give the material a very high melting point (~3530°C), high modulus (~440GPa) and hardness (25GPa).
Zirconium Carbide ZrC Melting Point
Zirconium carbide has a melting point of 3532 °C (6390 °F).
Zirconium carbide ZrC thermal conductivity.
The thermal conductivity of ZrC is 20.5 W/m K, the electrical conductivity (resistivity ~ 43 μΩcm)
Application of zirconium carbide ZrC powder
Zirconium carbide ZrC powder particles have the characteristics of high strength, high hardness, high temperature oxidation resistance, excellent toughness and thermal conductivity. They also have optical properties such as infrared reflectivity, high visible light absorption, and the ability to store large amounts of energy. Non-hafnium zirconium carbide and niobium carbide can be used as refractory coatings for nuclear reactors. Due to the small absorption cross section of muons and weak sensitivity to radiation damage, it can be used as a coating for uranium dioxide and thorium dioxide particles in nuclear fuel. Carbide is characterized by hardness; therefore, they can be used as drills and other wear-resistant tools. Nano-zirconium carbide ZrC powder can be used in nano-structure fields such as metallurgy, chemical industry, and aviation. Used in the textile industry to manufacture nylon, fiber and carbide thermostatic textiles. Zirconium carbide is also used in ceramic and metal matrix composites, which are also made from these nanoparticles.
Non-hafnium zirconium carbide (ZrC) and niobium carbide can be used as refractory coatings for nuclear reactors. Due to the small neutron absorption cross section and weak sensitivity to radiation damage, it can be used as a coating for uranium dioxide and thorium dioxide particles. Coatings are typically deposited in fluidized bed reactors by superheated chemical vapor deposition. It also exhibits high emissivity and high current capacity at high temperatures, making it a promising material for thermophotovoltaic radiators and field emitter tips and arrays.
Because of their hardness, cemented carbide compounds can be used as drills and other tools that require wear resistance. Zirconium carbide (ZrC) is an important high temperature structural material with high melting point, high strength and corrosion resistance. The application of cemented carbide can improve the strength and corrosion resistance of the material.
Nano zirconium carbide ZrC powder can be used in metallurgy, chemical industry, aviation and other nanostructure fields. It has been used in the textile industry to make thermostatic fabrics of nylon, fibers and carbide. Composites for ceramic and metal substrates are also made from these nanoparticles.

The EU’s draft REPowerEU plan calls for an increase of 15TWh of rooftop PV capacity by 2022. The draft also calls for EU and national governments to take action this year to reduce the time required to obtain permits for rooftop PV installations to three months, and proposes that "all new buildings and existing buildings with an energy grade OF D or above should have rooftop PV installations by 2025".
In addition, the European Commission is likely to set a target for installed PV capacity of 300GW by 2025 and 500GW by 2030. Some members are more aggressive, with Austria, Belgium, Lithuania, Luxembourg, and Spain demanding a 1TW target for 2030.
The REPowerEU initiative, worth 195 billion euros, was proposed by the EU on March 8 to phase out member states' dependence on Russian fossil fuels by 2030. In a few days, the European Commission will present a package to implement the RePowerEU strategy.
As an important application scenario of distributed PV, rooftop PV is not limited to land, and the development conditions are relatively convenient.
Since the end of 2021, Spain, France, the Netherlands, and other countries have introduced policies and measures such as government subsidies, tax cuts, fee reductions, and accelerated grid-connection approval to encourage the development of distributed PV. Europe's potential for rooftop PV is huge and will continue to be an important growth pole for the industry, according to Wood Mackenzie.
