Pulvis Metalli Wolframii 99.95% (W) CAS No. 7440-33-7
Pulvis tungsteni est pulvis metallicus subtilis e tungsteni (W) factus, notus ob proprietates suas eximias, inter quas altissimum punctum liquefactionis omnium metallorum, densitatem magnam, et firmitatem excellentem ad temperaturas elevatas.
Proprietates Claves
Punctum liquefactionis altum: 3422°C (6192°F)
Alta densitas: ~19.25 g/cm³ (auro simile)
Robur et duritia excellentes (etiam ad altas temperaturas)
Bona conductivitas electrica et thermalis
Resistentia corrosionis (resistens acidis et alcalibus)
Methodi Productionis
1. Reductio Hydrogenii: - Oxidum tungsteni (WO₃ vel WO₂) in atmosphaera hydrogenii reducitur.
- Reactio: \[WO_3 + 3H_2 \rightarrow W + 3H_2O \]
2. Reductio Carbonis (minus communis propter formationem carburi).
3. Mixtio mechanica (pro pulveribus tenuissimis vel nano-magnitudinis).
1. Metalla dura/Carbida cementata (WC-Co pro instrumentis secandis, terebris).
2. Electronica (filamenta, electroda, semiconductoria).
3. Res militares et aërospatiales (proiectiles perforantes arma, fistulae missilium).
4. Fabricatio Additiva (Impressio Tridimensionalis) pro partibus summae efficacitatis.
5. Praesidium contra Radiationem (praesidia contra radios X et radios gamma).
