99.95% Pauka Metala Tungsten (W) CAS No. 7440-33-7
He pauka metala maikaʻi ka pauka tungsten i hana ʻia mai ka tungsten (W), i ʻike ʻia no kona mau waiwai kūikawā, me ke kiko heheʻe kiʻekiʻe loa o nā metala āpau, ka nui o ka mānoanoa, a me ka ikaika maikaʻi loa i nā mahana kiʻekiʻe.
Nā Waiwai Koʻikoʻi
Kiʻekiʻe o ka hoʻoheheʻe ʻana: 3422°C (6192°F)
Kiʻekiʻe ka nui: ~19.25 g/cm³ (like me ke gula)
Ikaika a me ka paʻakikī maikaʻi loa (ʻoiai i nā mahana kiʻekiʻe)
ʻO ka hoʻokele uila a me ka wela maikaʻi
Ke kūpaʻa ʻana i ka palaho (kū i nā waikawa a me nā alkalis)
Nā ʻAno Hana
1. Hoʻēmi ʻia ka Hydrogen: - Hoʻēmi ʻia ka tungsten oxide (WO₃ a i ʻole WO₂) i loko o ka lewa hydrogen.
- Pane: \[ WO_3 + 3H_2 \rightarrow W + 3H_2O \]
2. Ka Hoʻemi ʻana o ke Kalapona (ʻaʻole i maʻamau ma muli o ke kūkulu ʻia ʻana o ka carbide).
3. Mechanical Alloying (no nā pauka ultrafine a i ʻole nano-sized).
1. Nā Carbides Paʻa/Cemented (WC-Co no nā mea hana ʻoki, nā wili).
2. Nā mea uila (nā filaments, nā electrodes, nā semiconductors).
3. Koa & Aerospace (nā mea hoʻolele pale kaua, nā nozzles rocket).
4. Hana Hoʻohui (Paʻi 3D) no nā ʻāpana hana kiʻekiʻe.
5. Palekana Radiation (pale X-ray a me gamma-ray).
