hao sulfur hao ii sulfide

Iron Sulfur: He Luʻu hohonu i loko o ka hao(II) SulfideIron(II) sulfide, ʻike ʻia hoʻi ʻo ferrous sulfide, he mea hoihoi ia me nā noi like ʻole a me nā waiwai kemika hoihoi. Nānā kēia ʻatikala i kona hoʻokumu ʻana, waiwai, hoʻohana, a me nā manaʻo pili e like me nā pūʻulu sulfur hao.

Hoʻokumu ʻia o Hao Sulfur Hao(II) Sulfida

Hao Sulfur Hao(II) Sulfida hana ʻia ma o nā ʻano hopena like ʻole, pili pinepine i ka hui ʻana o ka hao a me ka sulfur ma lalo o nā kūlana kikoʻī. ʻO kekahi ala maʻamau ka pane pololei ma waena o ka hao elemental a me ka sulfur ma nā wela kiʻekiʻe. He exothermic kēia hopena a hoʻopuka i ka nui o ka wela. ʻO ka hoohalike no kēia pane ʻana:Fe(s) + S(s) → FeS(s)Aʻe, Hao Sulfur Hao(II) Sulfida hiki ke hoʻoheheʻe ʻia mai nā hāʻina wai i loaʻa nā ion hao(II) (Fe²⁺) a me nā iona sulfide (S^2-). Ka hikiwawe o Hao Sulfur Hao(II) Sulfida he haʻahaʻa haʻahaʻa, e alakaʻi ana i kona ua ma nā haʻahaʻa haʻahaʻa o nā reactants. ʻO nā kūlana kikoʻī (pH, ka mahana, ka ʻike) e hoʻoikaika nui i ke ʻano a me ka crystallinity o ka hopena FeS.

Nā ʻano like ʻole a me nā ʻano Crystal

He mea nui e hoʻomaopopo i hiki ke noho ʻo FeS i nā ʻano crystalline like ʻole, kēlā me kēia me nā waiwai kūʻokoʻa. ʻO Mackinawite (tetragonal FeS), he ʻano metastable, ʻo ia ka hua mua o ka hopena o ka ua. I ka lōʻihi o ka manawa, hiki ke hoʻololi ʻia i nā pae paʻa e like me ka pyrrhotite a i ʻole troilite, e pili ana i ka mahana a me nā kūlana kaiapuni. ʻO ke aʻo ʻana i kēia mau hoʻololi ʻana he wahi ia o ka noiʻi mau.

Na waiwai o Hao Sulfur Hao(II) Sulfida

Hao Sulfur Hao(II) Sulfida he paʻa ʻeleʻele, ʻeleʻele me ka ʻulaʻula metala. Hiki ke ʻokoʻa kona hiʻohiʻona ma muli o ka maʻemaʻe a me ke ʻano crystalline. Loaʻa nā waiwai nui:

Waiwai	Waiwai	Nā memo
Lae hehee	1193 °C (Troilite)	Hiki ke ʻokoʻa iki ma muli o ke ʻano aniani
ʻO ka mānoanoa	4.7-4.8 g/cm3	Kokoke waiwai; pili i ke ʻano
Ka hoʻoheheʻe	Haʻahaʻa i ka wai	Hoʻopili me nā ʻakika

Hoʻopili ʻia ka ʻikepili ma muli o nā kumu like ʻole.

Nā noi o Hao Sulfur Hao(II) Sulfida

Hao Sulfur Hao(II) Sulfida loaʻa nā noi ma nā ʻoihana he nui, me:

Metallurgy

He mea ia i loko o kekahi mau mea hao a hoʻokani i nā hana hoʻoheheʻe hao.

Hoʻohui Kimia

He mea hoʻomaka a reagent i ka synthesis o nā pūhui sulfur ʻē aʻe.

ʻEpekema Kaiapuni

He mea koʻikoʻi ka hoʻomaopopo ʻana i kona hoʻokumu ʻana a me kāna ʻano i ke aʻo ʻana i nā pōʻai biogeochemical a me nā hana hoʻoponopono kaiapuni. Ka noho ana o Hao Sulfur Hao(II) Sulfida he mea hōʻike i nā kūlana kaiapuni kūikawā, e like me nā kaiapuni anaerobic i loko o ka sediment a i ʻole ka lepo. ʻO kāna hana ʻana me ka oxygen a me ka wai e kōkua i ke kaʻa ʻana o ka hao a me ka sulfur i kēia mau kaiapuni.

Nā Hui Hao-Sulfur: He Manaʻo Pili

ʻO nā puʻupuʻu hao-sulfur he mea koʻikoʻi koʻikoʻi i loko o nā enzymes he nui, e pāʻani ana i kahi hana koʻikoʻi i nā kaʻina olaola e like me ka hoʻoili electron a me ka catalysis. ʻO kēia mau pūʻulu, i loaʻa pinepine i ka hao a me ka sulfide i loko o nā hoʻonohonoho like ʻole (e laʻa, [2Fe-2S], [4Fe-4S]), aia i loko o kahi ākea o nā mea ola. ʻO ka hoʻomaopopo ʻana i ka kemika bioinorganic o kēia mau pūʻulu e hāʻawi i nā ʻike i nā ʻano hana olaola kumu. ʻO ka noiʻi hou aku e pili ana i ka synthesis a me ke ʻano o ia mau puʻupuʻu he mea nui ka ʻepekema.

No nā mea kiʻilika kiʻekiʻe, e noʻonoʻo e hoʻopili Inner Mongolia Xinxin Silicon Industry Co., Ltd no kou pono ʻoihana.

Nānā: ʻO ka ʻike i hāʻawi ʻia ma kēia ʻatikala no nā kumu hoʻonaʻauao wale nō. E ʻimi mau i nā pepa ʻikepili palekana kūpono (SDS) a e hahai i nā hana hoʻokolohua palekana i ka wā e lawelawe ai i nā kemika.
