VI. Frequently Asked Questions (FAQ)

Q1: What is the primary difference in powder quality between Water and Gas Atomization?

A: Water atomization produces irregular, dendritic particles, which is ideal for traditional Powder Metallurgy where mechanical interlocking is desired. Gas atomization yields highly spherical particles with low oxygen content, which is necessary for Additive Manufacturing (3D Printing) where good flowability is critical.

Q2: Are laboratory-scale atomizers suitable for making commercial powders?

A: Lab-scale atomizers are designed for R&D, alloy development, and small-batch production (typically $\text{< } 50 \text{ kg}$). While they provide commercial-grade powder quality, they are not economically viable for industrial tonnage production. They are perfectly suited for sampling and qualification runs.

Q3: How do I ensure safety when dealing with active metals like Titanium?

A: Active metals require strict adherence to protocols. They must be melted and atomized under a high vacuum or inert gas atmosphere (like in a Vacuum Melting/Atomization System). Powder handling must occur in an inert glove box to prevent spontaneous combustion.
