Production Method of Molybdenum Disulfide MoS2 Powder

Direct Synthesis

Mix molybdenum oxide (MoO₃) with sulfur powder. Heat the mixture to 800–1000°C in a furnace under inert gas. They react to form MoS₂. Cool and grind the product into powder.

Wet Chemical Process

Dissolve ammonium molybdate [(NH₄)₆Mo₇O₂₄] in water. Add hydrogen sulfide (H₂S) gas or sodium sulfide (Na₂S) solution. A MoS₂ precipitate forms. Filter, wash, and dry it at 100–150°C.

Hydrothermal Synthesis

Combine molybdenum chloride (MoCl₅), sulfur source (like thiourea), and water in a sealed container. Heat to 180–220°C under pressure. Tiny MoS₂ crystals grow. Collect and dry them.

Mechanical Exfoliation

Grind natural molybdenite ore (MoS₂) into fine powder. Use ball mills or ultrasonic treatment to break down large flakes into smaller particles.

Chemical Vapor Deposition (CVD)

Heat molybdenum trioxide (MoO₃) and sulfur powder in a furnace. Their vapors react on a substrate (like silicon) to form MoS₂ films. Scrape off the movie to get powder.
