Powder Metallurgy
Industrial powder-processing methods that make metal objects by producing metal powders, compacting or shaping them, and sintering or heating them below full melting.

| Prerequisite | Type | Confidence | Evidence level | Note | Sources |
|---|---|---|---|---|---|
| Advanced Metallurgy (Medieval) (advanced_metallurgy_medieval) | enabling | 72% | textbook | Powder metallurgy builds on prior metallurgical knowledge of metal ores, powders, heating, and working, but the scoped 1801 platinum-powder consolidation is a distinct later industrial process. |
|
| Precision Machine Tools (precision_machine_tools) | commercial_or_scaling_dependency | 58% | expert_inference | Precision dies, presses, and tooling matter for reproducible industrial powder-metallurgy parts, but they are not required for Wollaston's first platinum-powder consolidation. |
