Qhov sib txawv tseem ceeb ntawm stilbite thiab heulandite yog tias stilbite tuaj yeem tshwm sim hauv monoclinic, triclinic, thiab orthorhombic crystal systems, whereas heulandite tshwm sim hauv monoclinic crystal system.
Ob leeg stilbite thiab heulandite yog cov tswv cuab ntawm pawg tectosilicate thiab poob rau hauv pawg zeolites. Cov no yog cov tshuaj ntxhia tshwm sim.
Stilbite yog dab tsi?
Stilbite yog cov ntxhia zeolite uas los ntawm cov khoom siv tectosilicate. Muaj ob hom stilbite-Ca thiab stilbite-Na, raws li cov tshuaj muaj pes tsawg leeg. Ntawm ob daim ntawv no, stilbite-Ca yog daim ntawv tshaj plaws. Stilbite-Ca yog hydrous calcium, sodium thiab aluminium silicate compound qhov twg calcium npaum li cas dominates ntau npaum li cas sodium. Ntawm qhov tod tes, hauv stilbite-Na, tus nqi ntawm sodium dominates tshaj cov calcium.
Daim duab 01: Qhov tshwm sim ntawm Stilbite
Stilbite los nyob rau hauv qeb ntawm tectosilicates thiab zeolites. Nws muaj monoclinic crystal system. Tab sis tuaj yeem muaj cov ntaub ntawv triclinic lossis orthorhombic ib yam nkaus. Cov chav kawm siv lead ua ntawm stilbite yog prismatic, thiab feem ntau, cov pob zeb no zoo li tsis muaj xim, dawb, lossis xim liab. Nws muaj ib tug brittle qhov thiab lub luster yog vitreous. Ntxiv mus, qhov tawg ntawm stilbite yog conchoidal los yog tsis sib xws thiab qhia tau hais tias cov pob zeb hauv av dawb. Txawm li cas los xij, stilbite yog pob tshab rau translucent hauv nws qhov diaphaneity. Stilbite tuaj yeem yaj thiab decomposed hauv hydrochloric acid.
Feem ntau, cov muaju ntawm stilbite yog nyias tabular, flattened parallel mus rau qhov tseem ceeb cleavage. Txawm li cas los xij, peb tuaj yeem pom tias cov sib sau ua ke ntawm stilbite yog sheaf-like lossis bow-ties, fibrous thiab globular.
Thaum xav txog kev siv cov stilbite, nws cov qauv tuaj yeem ua raws li cov khoom siv molecular sieve, uas ua rau nws cais cov hydrocarbons thaum lub sij hawm cov txheej txheem roj av refining.
Heulandite yog dab tsi?
Heulandite yog ib hom tectosilicate ntxhia ntawm pawg zeolite, thiab nws yog hydrous calcium thiab aluminium silicate. Muaj ntau hom heulandite, uas suav nrog heulandite-Ca, heulandite-Na, heulandite-K, heulandite-Sr, thiab heulandite-Ba. Ntawm cov ntawv no, heulandite-Ca yog daim ntawv ntau tshaj.
Daim duab 02: Qhov tshwm sim ntawm Heulandite
Cov khoom ntxhia no muaj cov kab ke monoclinic siv lead ua, thiab nws cov chav siv lead ua yog prismatic. Heulandite mineral tshwm nyob rau hauv cov xim tsis muaj xim, daj, ntsuab, dawb, los yog daj ntseg liab xim. Nws tshwm sim nyob rau hauv tabular, parallel aggregates, uas muaj ib tug zoo meej basal cleavage. Cov ntxhia pob zeb no muaj pearly, vitreous luster thiab cov ntxhia streak xim yog dawb. Nws tuaj yeem yog pob tshab lossis translucent.
Qhov txawv ntawm Stilbite thiab Heulandite yog dab tsi?
Ob leeg stilbite thiab heulandite yog cov tswv cuab ntawm pawg tectosilicate uas los ntawm pawg zeolites. Cov no yog ib txwm tshwm sim minerals. Qhov sib txawv tseem ceeb ntawm stilbite thiab heulandite yog tias stilbite tuaj yeem tshwm sim hauv monoclinic, triclinic, thiab orthorhombic crystal systems, whereas heulandite tshwm sim hauv monoclinic crystal system. Ntxiv mus, stilbite muaj xim tsis muaj xim, dawb, lossis liab dawb, qhov heulandite muaj xim tsis muaj xim, daj, ntsuab, dawb lossis daj ntseg liab. Yog li, qhov no yog qhov txawv ntawm stilbite thiab heulandite nyob rau hauv cov nqe lus ntawm tsos. Tsis tas li ntawd, stilbite-Ca thiab stilbite-Na yog variations ntawm stilbite thaum heulandite-Ca, heulandite-Na, heulandite-K, heulandite-Sr, thiab heulandite-Ba yog variations ntawm heulandite.
Cov hauv qab no infographic teev qhov sib txawv ntawm stilbite thiab heulandite hauv daim ntawv teev npe rau ib sab ntawm kev sib piv.
Summary – Stilbite vs Heulandite
Ob leeg stilbite thiab heulandite yog cov tswv cuab ntawm pawg tectosilicate thiab poob rau hauv pawg zeolites. Cov no yog ib txwm tshwm sim minerals. Qhov sib txawv tseem ceeb ntawm stilbite thiab heulandite yog tias stilbite tuaj yeem tshwm sim hauv monoclinic, triclinic thiab orthorhombic crystal systems, whereas heulandite tshwm sim hauv monoclinic crystal system.
