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 Nitride powder are still very uncertain.
Introduction to Titanium Nitride TiN Powder
Titanium nitride or TiN is a golden cubic crystal. The molecular weight is 61.89. The melting point is 2950℃. The density is 5.43g/cm3.
Physicochemical Properties of Titanium Nitride TiN Powder
Titanium nitride is slightly soluble in hydrofluoric acid, aqua regia, and nitric acid, but insoluble in water. It has a high melting point and properties of high strength, high hardness, acid, alkali corrosion resistance, wear resistance, high-temperature chemical stability, and excellent electrical and thermal conductivity.
HSS cutting tools covered with titanium nitride film can reduce tool wear, increase chip speed, and extend service life. Titanium nitride is also widely used as watchcase, watchband, and other imitation gold alloy coatings. Titanium nitride whiskers are used to strengthen the metal and ceramic matrix composites. It is prepared by reaction of titanium and nitrogen at 1200℃.

Applications of Titanium Nitride Ceramic Materials
Titanium nitride is a new kind of multifunctional cermet material, which has excellent properties such as high melting point, high hardness, wear resistance, good chemical stability, good electrical and thermal conductivity, and light properties. Its melting point is 2930~2950℃, is a good conductor of heat and electricity, and has superconductivity at low temperatures. It is used to manufacture jet engines. Because of its unique golden metallic luster, titanium nitride is also used in the field of gold decoration.
1. Used for tool manufacturing
Titanium nitride ceramic coating has a golden yellow finish that looks nice on the cutting tool. However, its main function is not for decoration, it has a Vickers hardness (HV) of more than 2500, and the thickness of the coating on the tool is usually 3 to 5 microns. Higher wear resistance and heat resistance and longer service life than uncoated tools. Applying this technology to machinery in industrial production, such as coating the gear hob with titanium nitride, can extend the service life by 3 to 4 times, while cutting the gear can increase the cutting speed or feed or more, thus reducing the machining time of the material.
2. Used in biomedicine
The occluder used for the treatment of atrial septal defect, ventricular septal defect, and patent ductus arteriosus in congenital heart disease has been widely used in clinical medicine as an interventional implant. But the ordinary heart stoppers are mainly made from the nickel-titanium alloy material, nickel is as high as 55%. Excessive nickel can cause allergies to the human body, poisoning, and even cause cancer for long-term effects. And the Nitinol surface purification film of the common Nitinol occluders will be destroyed, releasing nickel ions in the complex human body environment.
Because titanium nitride is a biocompatible material (previously used in coronary stents), it is much less thrombogenic than nitride itself.
3. Used for the car front baffle film
Based on nano titanium nitride, the nano-ceramic film produced by magnetron sputtering technology and metal nitride technology is not easy to be corroded, is durable, does not shield mobile phone signals, good heat dissipation.
The difference between nano-ceramic insulation film and metal insulation film is as follows:
1. Different sunscreen and heat insulation effect
Metal film heat dissipation is worse than ceramic film, heat insulation effect is general, high reflective rate. Ceramic film through solar spectrum selective filtering function to achieve the purpose of heat insulation, heat insulation is far more than metal, lower reflective rate, excellent stability.
2. Different signal passing rates
Metal film and a key difference between ceramic membrane, cut off the signal rate, metal film have disruptive to import GPS, the ETC (no stop electronic toll collection system) is also, easy to affect all kinds of signals through the metal film is generally divided into single metal film and multilayer metal film, although multilayer metal film on the thermal insulation is better than that of the single-layer metal film. But because of its thickness, the signal is even more seriously blocked. The ceramic film, stripped of its metallic properties, does not shield the signal.
3. Different oxidation shelf life
The metal film is easy to oxidize, and the shelf life is slightly short, while the chemical properties of the ceramic film are more stable, not easy to oxidize, and can resist acid and alkali, and organic solvents, so as to have a long service life. The shelf life of general ceramic heat insulation film is 10 years, while the metal heat insulation film is generally 5 years.

Because of the conflict between Russia and Ukraine, there is a shortage of natural gas supply. At the same time, other renewable energy sources cannot produce enough electricity, so electricity prices have soared in many countries of the world. For this reason, I assume the supply and prices of the Titanium Nitride powder would keep being influenced by the high energy prices.
