Gazprom recently said it had completely suspended gas supplies to Bulgarian Gas company and Polish Oil and Gas Company (PGNiG) because it was not being paid in rubles. Russia said it would resume gas supplies after it agreed to pay for them in rubles.
Bulgaria and Poland announced Monday that they have received a notice from Russia to suspend natural gas supplies from Monday.
Russian President Vladimir Putin on March 31 signed a presidential decree to settle gas trade with "unfriendly" countries and regions in rubles. When the new rules took effect on April 1, Presidential press secretary Dmitry Peskov said Russia would not immediately "cut off gas" to Europe, as the cost of gas supplies starting April 1 should be settled in the second half of April or May.
Because of the ever-changing international situation, the supply and prices of international bulk 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
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.
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.

With Russia taking the lead on Poland and Bulgaria at the end of last month, there appears to be a growing sense of compromise within the EU over whether to accept Moscow's proposed rouble settlement order.
Italy's prime minister said recently that European companies would be able to buy gas in roubles without violating sanctions. This apparently ignores the guidance of hardliners in the EU to "fight to the end".
For weeks, European companies have been trying to find ways to meet Russia's payment demands for the rouble while maintaining vital gas supplies without violating sanctions against Moscow.
Late last month, European Commission President Von der Leyen said operating under the mechanism would violate sanctions and asked European companies not to bow to Russian demands. However, the EU has yet to issue more rigorous written guidelines on how companies should pay Gazprom.
The Italian prime minister said recently, "There is no official announcement from the European Union about what ruble settlement means for sanctions violations, and no one has said whether ruble payments violate sanctions or not. It's a grey area."
"In fact, most gas importers are already opening rouble accounts for deals with Gazprom,"
He also used German companies as a shield. He said Germany's largest gas importer had already paid in rubles. "In fact, we saw evidence yesterday that the largest gas importer in Germany has already paid in rubles."
