The World Bank expects global economic growth to slow significantly, from 5.5% in 2021 to 4.1% in 2022 and further to 3.2% in 2023. Growth in East Asia and the Pacific is expected to slow to 5.1 percent in 2022, reflecting the impact of China's economic slowdown, the report said. China's economic growth is expected to fall to 5.1% in 2022, close to potential growth, due to the ongoing impact of the COVID-19 pandemic and the Chinese government's tightening of regulations in certain sectors of the economy. The report said that the rapid spread of the Omicron variant means that the new crown epidemic is likely to continue to disrupt economic activity in the near future. In addition, decelerating growth in major economies, including the United States and China, will depress external demand in emerging markets and developing economies.
Slow economic growth has a huge impact on Molybdenum Carbide powder.
Introduction to Molybdenum Carbide Mo2C Powder
The molecular formula of molybdenum carbide is Mo2C, the molecular weight is 203.88, and the carbon content is 5.89%. It is a dark gray metallic powder, which crystallizes into a dense hexagonal lattice. The density is 9.18g/cm3, and the melting point is 2690℃.
As a kind of new functional material with high melting point and hardness, good thermal and mechanical stability, and good corrosion resistance, it has been widely used in various fields of high-temperature resistance, friction resistance, and chemical corrosion resistance.
With similar electronic structure and catalytic properties to noble metals, it can be widely used as catalysts for reactions involving hydrogens, such as isomerization of alkanes, hydrogenation of unsaturated hydrocarbons, hydrodesulfurization, and denitrification. High hardness, wear resistance, abrasion resistance. It is an important component of molybdenum-molybdenum carbide hard coating and other cermet coatings, and can also be used as wear-resistance and scratch resistance coating.
Structure of Molybdenum Carbide Mo2C
Metallic carbides are generally considered to have an interstitial alloy structure. In normal gap alloys, metal atoms are arranged in forms such as face-centered cubic (FCC), hexagonal dense stack (HCP), and simple hexagonal (HEX), with nonmetallic atoms entering the Spaces between the metal atoms. The most common types of gaps between metal atoms are octahedral and triangular prism. The crystal structure of metallic carbides depends on both geometrical and electronic factors. The geometrical factors can be described by Hagg's empirical rule: when the atomic ratio of nonmetal to metal is lower than 0.59, a simple crystal structure is formed. Interestingly, although metallic carbides have simple crystal structures, few of these compounds have the same crystal structure as their parent metals. For example, molybdenum metal has a body-centered cube structure, while its stable carbides have a hexagonal compact pile structure, and carbon oxides have a face-centered cube structure. Another factor that determines the crystal structure of gap alloys is the electron factor. Bonding in these compounds results from the cooperation between the s-P orbital of the nonmetallic and the S-P-D orbital of the metal atom.

Applications of Molybdenum Carbide Mo2C Powder
1. Nano molybdenum carbide is used as a coating material and can also be used as an additive material. In addition, it is usually used for particle reinforced alloys.
2. Molybdenum carbide has a similar electronic structure and catalytic properties to precious metals, with the catalytic activity of hydrogen denitrification, hydrolysis, and isomerization reaction.
Molybdenum carbide is in phase with platinum-group noble metals in many ways. In particular, its hydrogenation activity is comparable to that of Pt, Pd, and other precious metals, and it is expected to be a substitute for precious metals.
4, can manufacture chromium-free special alloy and engineering ceramics, etc. Used as hard tool material, wear-resistant material, heating material, and high-temperature structure material.
5, used for the production of wear-resistant film and the semiconductor film. It can also be used as raw material to produce molybdenum carbide. It can be used to manufacture special alloys and engineering ceramics without chromium.
