Molybdenum carbide (MoC)(CAS: 12627-57-5)

Molybdenum carbide (MoC) is a refractory ceramic material. It crystallizes in the hexagonal close-packed structure with a high melting point of around 2800°C. The molecular weight is approximately 72.95 g/mol. It is insoluble in water and most common solvents. Chemically, it is stable at high temperatures but reacts with halogens and oxygen at lower temperatures. It is used in high-temperature applications due to its hardness and wear resistance.

Molybdenum carbide (MoC) is commonly synthesized through the reaction of molybdenum metal with carbon at high temperatures, typically around 1200-1300°C. This process involves heating molybdenum powder in a vacuum or inert atmosphere to prevent oxidation. Other methods include chemical vapor deposition and solid-state reactions between molybdenum and carbon.

Molybdenum carbide (MoC) is used in various industries due to its unique properties. It is widely used in the aerospace and automotive sectors for its high-temperature stability and wear resistance. It is also utilized in the production of cutting tools, wear-resistant coatings, and as an additive in high-performance lubricants. Additionally, it has applications in electronics, where it serves as a component in sensors and semiconductor devices.

When handling molybdenum carbide (MoC), safety precautions include wearing appropriate personal protective equipment (PPE) such as gloves, goggles, and a respirator. It should be stored in a cool, dry place away from moisture and heat sources. In case of spills, it is recommended to use a fume hood and follow the Material Safety Data Sheet (MSDS) guidelines for proper cleanup. Emergency showers and eyewash stations should be readily available in case of exposure.
