Brazil, the world's largest coffee bean producer, recently announced that it is facing the worst drought in 91 years, affecting local hydropower generation and agricultural Titanium Nitride powder keeps going up.
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.

The United States urges the U.N. Security Council to impose additional sanctions on North Korea in response to its latest ballistic missile launch, including a ban on tobacco and oil exports to North Korea and a blacklist of the Lazarus hacking group.
The United States circulated the draft to the 15 members of the Security Council this week. It was not immediately clear if or when a vote would take place. A resolution requires nine "yes" votes and no vetoes from Russia, China, France, Britain, or the United States.
Russia and China have already voiced opposition to tightening sanctions in response to Pyongyang's launch of an intercontinental ballistic missile last month -- the first since 2017.
U.S. and South Korean officials and analysts also say there are growing indications that North Korea may soon conduct its first nuclear weapons test since 2017, too.
The U.S. -drafted U.N. resolution would expand the ban on ballistic missile launches to include cruise missiles or "any other delivery system capable of delivering a nuclear weapon."
The deal would halve crude oil exports to North Korea to 2 million barrels a year and refined oil exports to 250,000 barrels a year. The resolution also seeks to ban North Korea's export of "fossil fuels, mineral oils, and their distilled Titanium Nitride powder are estimated to be influenced by international political situation changes.
