sulfur maʻemaʻe kiʻekiʻe

I kēia lā, e kūkākūkā mākou i ka sulfur maʻemaʻe kiʻekiʻe.
He mea maʻamau ka Sulfur me nā hoʻohana like ʻole. Loaʻa ia i loko o ka pauda (kekahi o nā "Four Great Inventions"), hoʻohana ʻia i ka lāʻau lapaʻau Kina kuʻuna no kāna mau waiwai antimicrobial, a hoʻohana ʻia i ka vulcanization rubber e hoʻomaikaʻi i ka hana waiwai. ʻO ka sulfur maʻemaʻe kiʻekiʻe, akā naʻe, ʻoi aku ka nui o nā noi:
Nā mea nui o ka Sulfur Ma'ema'e Ki'eki'e
1. ʻOihana Uila
o Mea Semiconductor: Hoʻohana ʻia e hoʻomākaukau i nā semiconductors sulfide (e laʻa, cadmium sulfide, zinc sulfide) a i ʻole he dopant e hoʻomaikaʻi ai i nā waiwai waiwai.
o Lithium Batteries: ʻO ka sulfur maʻemaʻe kiʻekiʻe he mea koʻikoʻi o nā cathodes pākahi lithium-sulfur; ʻO kona maʻemaʻe e pili pono ana i ka ikehu a me ke ola pōʻai.
2. Hoʻohui Kimia
ʻO ka hana ʻana o ka ʻakika sulfuric maʻemaʻe kiʻekiʻe, ka sulfur dioxide, a me nā mea kemika ʻē aʻe, a i ʻole ma ke ʻano he kumu sulfur i loko o ka synthesis organik (e laʻa, nā mea waena lāʻau lapaʻau).
3. Nā Mea Hana Optical
o Ka hana ʻana i nā lens infrared a me nā mea puka makani (e laʻa, nā aniani chalcogenide) ma muli o ke kiʻekiʻe o ka hoʻouna ʻana i nā pae hawewe kikoʻī.
4. ʻO nā lāʻau lapaʻau
o Mea maka no nā lāʻau lapaʻau (e laʻa, nā ʻaila sulfur) a i ʻole nā ​​​​mea lawe no ka lepili radioisotope.
5. ʻImi ʻepekema
o Ka hoʻohuihui ʻana o nā mea hana superconducting, quantum dots, a i ʻole nano-sulfur particles, e koi ana i ka maʻemaʻe kiʻekiʻe loa.

Nā Hana Hoʻomaʻemaʻe Sulfur Maʻemaʻe Kiʻekiʻe e Sichuan Jingding Technology
Hoʻokumu ka hui i ka 6N (99.9999%) uila-maʻemaʻe kiʻekiʻe sulfur me ka hoʻohana ʻana i kēia mau ʻenehana:
1. Hoʻomāmā
o Ke Kumu: Hoʻokaʻawale i ka sulfur (kahi hoʻolapalapa: 444.6°C) mai nā mea haumia ma o ka momi a i ʻole ka distillation ea.
o Nā mea maikaʻi: Hana ʻia ma ka ʻoihana.
o Cons: Hiki ke hoʻopaʻa i nā haumia me nā wahi paila like.
2. Hoomaemae Wahi
o Kumu: Hoʻoneʻe i kahi wahi hoʻoheheʻe e hoʻohana i ka hoʻokaʻawale haumia ma waena o nā pae paʻa a me ka wai.
o Pono: Loaʻa i ka maʻemaʻe kiʻekiʻe loa (>99.999%).
o Cons: Haʻahaʻa kūpono, kiʻekiʻe ke kumu kūʻai; kūpono no ka lab a i ʻole ka hana liʻiliʻi.
3. Hoʻomoe ʻana i ka mahu (CVD)
o Kumu: Hoʻoheheʻe i nā sulfides kinoea (e laʻa, H₂S) e waiho i ka sulfur maʻemaʻe kiʻekiʻe ma luna o nā pani.
o Nā mea maikaʻi: He kūpono no nā mea kiʻiʻoniʻoni lahilahi me ka maʻemaʻe loa.
o Cons: ʻO nā lako paʻakikī.
4. Ka hoʻoheheʻe ʻia ʻana
o Kumu: Hoʻokala hou i ka sulfur me ka hoʻohana ʻana i nā mea hoʻoheheʻe (e laʻa, CS₂, toluene) e wehe i nā haumia.
ʻO nā mea maikaʻi: kūpono no nā haumia organik.
o Cons: Pono ka lawelawe ʻana i nā mea hoʻoheheʻe ʻawaʻawa.

ʻO ka hoʻoponopono ʻana i ke kaʻina hana no ka papa uila/optical (99.9999%+)
Hoʻohana ʻia nā hui e like me ka hoʻomaʻemaʻe ʻāina + CVD a i ʻole CVD + solvent crystallization. Hoʻopili ʻia ka hoʻolālā hoʻomaʻemaʻe i nā ʻano haumia a me nā koi maʻemaʻe, e hōʻoia ana i ka pono a me ka pololei.
Hoʻohālikelike ka approach i ke ʻano o nā ʻano hybrid e hiki ai i ka hoʻomaʻemaʻe maʻalahi a me ka hana kiʻekiʻe no nā noi ʻokiʻoki i ka uila, mālama ikehu, a me nā mea holomua.
