Preparation method of titanium carbide TiC powder

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 Titanium Carbide TiC Powder,Overview of Titanium Carbide TiC Powder,Application of Titanium Carbide TiC Powder,Titanium carbide TiC powder price,Titanium Carbide TiC Powder Supplier are still very uncertain.

Overview of Titanium Carbide TiC Powder

The chemical formula of titanium carbide is TiC. It is a steel grey crystal with a metallic sheen. It is thermally and electrically conductive, and its electrical conductivity decreases with increasing temperature, thus taking on the properties of a medal. It is a hard, high-melting compound, second only to diamond in hardness, with a microhardness of 2850 kg/mm2. The lattice constant a=4.173×10-8cm. The melting point is 3150 ℃, the boiling point is 4820 ℃, and the relative density is 4.9. TiN and TiO have the same lattice and the same parameters, so a series of continuous solid solutions can be formed between them. Heating above 1500 °C in H2 gas, C removal occurs gradually. The mixture of Ti(C,N) carbon nitride reacts with N2 gas above 1200 ℃ to form a variable composition. The oxidation rate of TiC is slow at 800 °C, but TiC powder can be combusted in O2 at 600 °C to generate TiO2 and CO2. At 1200 °C, it reacts with O2 gas to generate TiO2 and CO. It does not interact with water, but can react with water vapor to generate TiO2, CO and H2 at temperatures above 700 °C. Does not react with CO, but reacts with CO2 at 1200 °C to generate TiO2 and CO. Insoluble in hydrochloric acid and lye, soluble in nitric acid and aqua regia.

Preparation method of titanium carbide TiC powder

1. Carbon black for carbothermic reduction at 1700-2100 ℃

To reduce TiO2, the chemical reaction formula is: TiO2(S)+3C(s)=TiC(S)+2CO(g).

  2. Direct carbonization method TiC is prepared by the reaction of Ti powder and carbon powder. Ti(s)+C(s)=TiC The application of this method is limited due to the difficulty in preparing submicron titanium powders. The above reaction takes 5-20 hours to complete, the reaction process is difficult to control, and the reactants are seriously agglomerated. It requires further grinding to prepare fine TiC powder. In order to obtain a purer product, the fine powder after ball milling needs to be purified by chemical methods.

3. Chemical vapor deposition

The synthesis method utilizes the reaction between TiCl4, H2 and C

. TiCl4(g)+2H2(g)+C(s)=TiC(g)+4HCl(l)

Reactants react with hot tungsten or carbon monofilament. TiC crystals are grown directly on the monofilament. The yield and sometimes even the quality of TiC powder synthesized by this method is severely limited.

4. Sol-gel method

The invention relates to a method for fully mixing and dispersing a material and a solution to prepare a small particle size product. It has the advantages of good chemical uniformity, small powder particle size, narrow distribution and low heat treatment temperature, but the synthesis process is complicated and the drying shrinkage rate is large.

5. Microwave method

Using nano-titanium dioxide and carbon black as raw materials, using the principle of carbothermal reduction reaction, the material is heated by microwave energy. In fact, the dielectric loss of the material in the high-frequency electric field is used to convert microwave energy into thermal energy, so that nano-TiO2 and carbon can synthesize TiC.

TiO2+3C=TiC+2CO(g)

Application of Titanium Carbide TiC Powder

1. Titanium carbide powder is used for high temperature thermal spraying materials, welding materials, hard coating materials, military aviation materials, carbides and cermets.

2. Titanium carbide powder is used as an additive in the production of thermistors to improve wear resistance.

3. Titanium carbide powder has a NaCl-type cubic crystal structure. Adding 6% to 30% of TiC to WC-Co cemented carbide forms a TiC-WC solid solution with WC, which can significantly improve red heat, wear resistance, oxidation resistance, Corrosion resistance and other properties, more suitable for processing steel than WC-Co cemented carbide. Alloys such as Ni-Mo can also be used as binders to form tungsten-free cemented carbides, which can improve the turning speed and the precision and finish of the workpiece.

4. Used as tool material and additive for metal bismuth, zinc, cadmium smelting crucible, preparation of semiconductor wear-resistant film, HDD large-capacity storage equipment, is an important part of cemented carbide, used as deoxidizer in steelmaking industry, also Used as cermet, it has the characteristics of high hardness, corrosion resistance and good thermal stability.

"Is there talk of solidarity with Sweden and Finland joining NATO? No." "So is the West united?" Zelensky said at this Ukraine-hosted breakfast in Davos. No." "Our strength is unity within the country," Zelensky said. "Now it depends on the Unity of the West to stand strong and firm behind Ukraine against Russia.

According to Zelensky, "When we are all really united, we will have an advantage over Russia."  

Ukrainian President Volodymyr Zelensky says he once again appreciates U.S. President Joe Biden's offer of $40 billion in new financial aid to Ukraine.  

"We need the support of a united Europe," Zelensky stressed. Zelensky criticized the position of Hungarian Prime Minister Viktor Orban, who is reluctant to impose an embargo on Russian oil at this stage. "Hungary has a problem!" Zelensky criticized.
