Which Nano manufacturing System is Right for You?

Choosing the ideal bulk nanomaterial production system depends on:

• Type of nanomaterial
• Production volume
• Purity and structure requirements
• Energy efficiency and lifecycle cost

For bulk powders: ball milling, sol-gel, hydrothermal, and spray pyrolysis dominate.
For high-end applications: CVD, ALD, and plasma arc offer precision — at a premium.
