Guotai Junan released a research report saying that under the background of carbon neutrality, the scarcity of coal mines is prominent, and the value of assets will continue to increase. The high point of capital expenditure in the coal industry appeared in 2012. Under the general direction of carbon neutrality, the overall investment in the industry has slowed down, and capital expenditure has gradually declined. From 2021 to now, the Energy Bureau of the National Development and Reform Commission has only newly approved 17.4 million tons of Mo2C Powder.

How is Molybdenum Carbide Mo2C Powder produced?
1. Generally, molybdenum carbide powder is made first (using molybdenum and carbon direct chemical method, metal oxide and carbon reduction-chemical method, vapor deposition method and self-propagating high-temperature synthesis method), and then in a vacuum or reducing atmosphere in the carbon tube Furnace, molybdenum wire furnace, high-frequency vacuum furnace for sintering (reaction sintering, hot pressing sintering and hot isostatic pressing sintering are mostly used).
2. After the molybdenum powder and carbon black are fully mixed, they are ground by a ball mill and pressed into shape. In a hydrogen gas stream, the product is calcined at 1350-1500°C, and then the calcined product is cooled, crushed, and ground. Or use molybdenum trioxide or molybdenum dioxide instead of molybdenum powder reduction method.
3. Auxiliary metal bath method.
Using cobalt as the auxiliary metal, select Mo: Co to form a metal bath at a ratio of 1:(1～1.5), heat it in a pure graphite crucible with a Taman furnace in a hydrogen stream to 1800°C, and cool it (heating to 1800°C within 1h) ℃, keep at 1800℃ for 2～3h, cooling to room temperature takes 2h), crush the solidified product in the crucible, treat it with warm hydrochloric acid, and dissolve and remove the cobalt, and then obtain powdered Mo2C with a particle size of 150～350μm, the purity is: Containing 5.82%～5.85% (mass) of bound carbon, 0.26%～0.32% (mass) of free carbon, 6.08%～6.17% (mass) of total carbon.
4. Manufactured by the carbonization of metallic molybdenum.
Molybdenum trioxide MoO3 is hydrogenated and reduced to obtain molybdenum powder. Then the mixture of molybdenum powder and carbon black [Mo934% (mass) C6.6% (mass)] is dry-mixed with a ball mill for about 10 hours, and molded under pressure at a pressure of about 1t/cm2. Put the pressurized material block into a graphite pan or crucible, and heat it to 1400～1500 in a hydrogen stream (using pure hydrogen with a dew point of about -35℃) with a Taman furnace or an induction heating furnace (see picture) ℃, keep at this temperature for about 1h. Carbonize molybdenum to generate Mo2C.
5. Using synthetic methods.
First, the molybdenum powder is thoroughly mixed with carbon black [containing V6.6% (mass fraction)] according to Mo93.4% (mass fraction), then ground by a ball mill for 1 hour, pressurized to form, and put into an induction furnace. In hydrogen gas flow, calcining at 1350-1500°C for 1h, and then cooling, pulverizing and grinding the calcined product to obtain the product. Molybdenum trioxide or molybdenum dioxide can also be used instead of molybdenum powder for reduction to obtain molybdenum carbide.
Applications of Molybdenum Carbide Mo2C Powder:
Molybdenum carbide is a new functional material with a high melting point, high hardness and excellent anti-corrosion properties. It has been widely used in various high temperature, abrasion and chemical corrosion fields. It has a similar noble metal electronic structure and catalytic performance.
1. Due to its electronic structure and catalytic performance similar to noble metals, molybdenum carbide can be widely used as a catalyst for reactions involving hydrogens, such as the isomerization of alkanes, the hydrogenation of unsaturated hydrocarbons, hydrodesulfurization and denitrification;
2. Molybdenum carbide is an important component of molybdenum-molybdenum carbide hard coatings and other cermet coatings, and can also be used alone as a wear-resistant and wear-resistant coating;
2. Molybdenum carbide is widely used in hydrogen-related reactions such as alkanes;
3. Molybdenum carbide can be used to produce chromium-free special alloys and engineering ceramics;
4. Molybdenum carbide is used as super-hard tool material, wear-resistant material, heating element material and high-temperature structural material;
5. Molybdenum carbide is used to produce wear-resistant films and semiconductor films;
6. Molybdenum carbide can be used to make chromium-free special alloys and engineering ceramics.

Molybdenum Carbide Health & Safety Information
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 Mo2C Powder are estimated to be influenced by international political situation changes.
