In terms of international pricing benchmarks, according to the CP data released by Saudi Aramco, the propane contract price (CP) in March was $895 / ton, up $120 / ton from the previous month, up 15.48% from the previous month and up 43.20% from the same period last year. Butane contract price (CP) in March was 920 US dollars/ton, up 145 US dollars/ton compared with last month, up 18.71% month-on-month, up 54.62% compared with the same period last year; In March, CP in Saudi Arabia rose sharply, giving a strong boost to the international and domestic LPG market. Benchmark LPG prices are higher than a year ago as the economy continues to recover and demand for crude oil continues to repair. According to this trend, the market price of Molybdenum Carbide Mo2C will also be affected to a certain extent.
Overview of molybdenum carbide Mo2C powder
Molybdenum carbide Mo2C, the molecular weight is 203.88, and the carbon content is 5.89%. It is a dark grey metallic powder with a tightly packed hexagonal lattice. The density is 9.18g/cm and the melting point is 2690℃. As a new functional material, it has high melting point and hardness, good thermal and mechanical stability, and good corrosion resistance. It has been widely used for high temperature resistance, wear resistance and chemical corrosion resistance. Place.
Molybdenum carbide has a hexagonal crystal structure with a = 0.30029 nm and c = 0.472895 nm. Micro Vickers hardness (50g load) is 1950kg/mm2 (compared to 2080kg for WC). / mm2 is softer) with a melting point of 2687°C.
How is molybdenum carbide Mo2C powder produced?
1. Generally, molybdenum carbide powder is first made (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 made into carbon in vacuum or reducing atmosphere. Sintering is carried out in tube furnace, molybdenum wire furnace and high frequency vacuum furnace (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 with a ball mill and pressed into shape. In a stream of hydrogen, the product is calcined at 1350-1500°C, then the calcined product is cooled, pulverized and ground. Or use molybdenum trioxide or molybdenum dioxide instead of molybdenum powder reduction method.
3. Auxiliary metal bath method. With cobalt as auxiliary metal, choose Mo:Co to 1:(1 ~1.5) to form a metal bath, heated to 1800°C in a pure graphite crucible with a Taman furnace in a hydrogen stream, cooled (heated to 1800°C within 1h)°C, kept at 1800°C for 2 to 3h, and cooled to room temperature for 2h) , pulverize the solidified product in a crucible, treat it with warm hydrochloric acid, dissolve and remove cobalt, and obtain powdery Mo2C with a particle size of 150-350 μm, and the purity is: containing bound carbon 5.82% ～ 5.85% (mass), free carbon 0.26% ～ 0.32% (mass), total carbon 6.08% to 6.17% (mass).
4. Made of metal molybdenum carbide.
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)] was dry-blended with a ball mill for about 10 hours, and formed under a pressure of about 1t/cm2. The pressurized block was placed Put it into a graphite plate or crucible, and use a Taman furnace or an induction heating furnace to heat it to 1400 ~ 1500 °C (see picture) in a hydrogen flow (using pure hydrogen with a dew point of about -35 °C), and keep it at this temperature for about 1h . Molybdenum carbide produces Mo2C.
5. Use synthetic methods.
First, the molybdenum powder was fully mixed with Mo93.4% (mass fraction) and carbon black [containing V6.6% (mass fraction)], then ground with a ball mill for 1 hour, pressure-molded, and placed in an induction furnace. In a hydrogen stream, calcined at 1350-1500 ° C for 1 h, and then the calcined product was cooled, pulverized and ground to obtain the product. Molybdenum trioxide or molybdenum dioxide can also be used instead of molybdenum powder for reduction to obtain molybdenum carbide.
Application of Molybdenum Carbide Mo2C Powder
Molybdenum carbide is a new functional material with high melting point, high hardness and excellent corrosion resistance. It has been widely used in various fields of high temperature, wear resistance and chemical corrosion. It has similar noble metal electronic structure and catalytic properties.
1. Because its electronic structure and catalytic properties are similar to those of noble metals, molybdenum carbide can be widely used as a catalyst for reactions involving hydrogen, such as alkane isomerization, unsaturated hydrocarbon hydrogenation, hydrodesulfurization, denitration, etc.;
2. Molybdenum carbide is an important part of molybdenum-molybdenum carbide hard coating and other cermet coatings, and can also be used as wear-resistant and wear-resistant coatings alone;
3. Molybdenum carbide can be used to produce chromium-free special alloys and engineering ceramics;
4. Molybdenum carbide is used as superhard tool material, wear-resistant material, heating element material, high temperature structural material;
5. Molybdenum carbide is used to produce wear-resistant films and semiconductor films;
6. Molybdenum carbide can be used to manufacture special alloys and engineering ceramics without chromium;

Since February, gold has enjoyed a smooth upward run on the back of surging US inflation and the brewing of war. While expectations of rate rises have also risen in tandem over this period, gold had been largely pre-priced and the underlying driver of tightening expectations had come from inflation continuing to rise to record highs. The risk aversion caused by the continued tension in the war also provided an important short-term support for gold. This will have a certain impact on the price of the Molybdenum Carbide Mo2C and the market of the Molybdenum Carbide Mo2C.
