Sphalerite - zinc sulfide

Maminolo a sphalerite gem crystal.

Gulani zachilengedwe sphalerite mu sitolo yathu

Sphalerite ndiye mchere waukulu wa zinc. Amakhala makamaka zinc sulfide mu mawonekedwe a crystalline. Koma pafupifupi nthawi zonse imakhala ndi chitsulo chosinthika. chitsulo chikakhala chambiri, chimakhala chakuda chakuda, marmatite. Nthawi zambiri tinkapeza kuphatikiza ndi galena, komanso ndi pyrite ndi sulfides ena.

Pamodzi ndi calcite komanso dolomite ndi fluorite. Amadziwikanso kuti ochita migodi amatchula sphalerite ngati chisakanizo cha zinc, blackjack ndi ruby ​​​​jack.

Mchere umawonekera mu cubic crystal system. Mu mawonekedwe a kristalo, maatomu a zinki ndi sulfure ali ndi kulumikizana kwa tetrahedral. Kapangidwe kake kamagwirizana kwambiri ndi kapangidwe ka diamondi.

Analogi ya hexagonal ndi mawonekedwe a wurtzite. Kukhazikika kwa lattice kwa zinc sulfide mu zinc osakaniza makristalo kapangidwe ndi 0.541 nm, owerengedwa kuchokera geometry ndi ion matabwa a 0.074 nm zinki ndi 0.184 nm sulfide. Amapanga zigawo za ABCABC.

Zinthu

Miyala yonse yachilengedwe ya sphalerite imakhala ndi malire azinthu zosiyanasiyana zonyansa. Monga ulamuliro, iwo m'malo malo a nthaka mu maukonde. Cd ndi Mn ndizofala kwambiri, koma Ga, Ge ndi In zitha kupezekanso m'malo okwera kwambiri a 100 mpaka 1000 ppm.

Zomwe zili muzinthuzi zimatsimikiziridwa ndi zomwe zimapangidwira kupanga kristalo wa sphalerite. Izi ndizofunikira kwambiri pakuumba kutentha komanso kapangidwe kamadzimadzi.

Mtundu

Mtundu wake nthawi zambiri umakhala wachikasu, wofiirira, kapena imvi mpaka imvi-wakuda, ndipo ukhoza kukhala wonyezimira kapena wosawoneka bwino. Kuwala ndi kofanana ndi diamondi, kumakhala kosalala ku submetallic kwamitundu yokhala ndi chitsulo chochuluka. Ili ndi gulu lachikasu kapena lofiirira, kuuma kwa 3.5 mpaka 4, ndi mphamvu yokoka ya 3.9 mpaka 4.1. Zitsanzo zina zimakhala ndi zofiira zofiira mu makhiristo a imvi-wakuda.

Dzina lawo ndi Ruby Sphalerite. Mitundu yotuwa yachikasu ndi yofiira imakhala ndi chitsulo chochepa kwambiri ndipo ndi yomveka bwino. Mitundu yakuda komanso yosawoneka bwino imakhala ndi chitsulo chochulukirapo. Zitsanzo zina zimakhalanso fluoresce pansi pa kuwala kwa ultraviolet.

Refractive index yoyezedwa ndi kuwala kwa sodium, 589.3 nm, ndi 2.37. Imawala mu mawonekedwe a kristalo wa isometric ndipo imakhala ndi zida zabwino kwambiri za dodecahedral cleavage.

sphalerite katundu

Gawo lotsatirali ndi sayansi yabodza komanso yozikidwa pazikhulupiliro za chikhalidwe.

Krustalo yosangalatsayi idzakuthandizani kugwirizanitsa mawonekedwe anu achikazi ndi achimuna komanso kumasula luso lanu. Uwu ndi kristalo wamphamvu womwe ungakukhazikitseni uzimu, makamaka ngati musinkhasinkha ndi makhiristo ndi miyala yomwe imagwira ntchito ndi chakras apamwamba.

Ilinso kristalo yochiritsa yomwe ingapindulitse thupi lanu pamlingo wakuthupi, wamalingaliro, wamaganizidwe komanso wauzimu.

Kodi mungadziwe bwanji sphalerite?

Chimodzi mwazinthu zodziwika bwino za kristalo wa sphalerite ndiubwino wake waukulu kuposa wa diamondi. Ilinso ndi mizere isanu ndi umodzi yabwino kwambiri yokhala ndi nkhope kuyambira tarry mpaka diamondi sheen. Zitsanzo zosonyeza kugawanika kumeneku n'zosavuta kuzizindikira.

Kodi mineral sphalerite imapezeka bwanji?

Mwalawu umakumbidwa kuchokera pansi pa nthaka. Ndi miyala ya zinc yomwe imapanga m'mitsempha, yomwe imakhala ndi miyala yayitali ndi mchere womwe umapanga pansi pa nthaka. Pachifukwa ichi, migodi ya pansi pa nthaka ndiyo njira yabwino yopangira migodi. Njira zina zamigodi, monga kukumba dzenje lotseguka, zingakhale zodula komanso zovuta.

Natural sphalerite imagulitsidwa m'sitolo yathu yamtengo wapatali
