Qhov sib txawv tseem ceeb ntawm pyrolusite thiab psilomelane yog pyrolusite muaj tetragonal siv lead ua kab ke, qhov psilomelane muaj monoclinic siv lead ua system.
Pyrolusite thiab psilomelane yog ob yam khoom siv sib txawv uas muaj manganese atoms. Txawm hais tias ob qho tib si yog cov ntxhia oxide, peb tuaj yeem txheeb xyuas qhov sib txawv ntawm pyrolusite thiab psilomelane los ntawm lawv cov tsos.
YPyrolusite yog dab tsi?
Pyrolusite yog cov ntxhia oxide feem ntau muaj manganese dioxide. Nws yog ib qho tseem ceeb ore rau manganese hlau. Cov ntxhia pob zeb no tshwm nyob rau hauv tsaus dub mus rau lub teeb grey, qee zaum bluish, nyob ntawm cov impurities tam sim no hauv cov ntxhia. Cov txheej txheem siv lead ua ntawm cov pob zeb no yog tetragonal, thiab cov tshuaj formula tuaj yeem muab tau ua MnO2. Cov ntxhia no feem ntau muaj amorphous, granular, fibrous lossis columnar qauv uas qee zaum tsim cov crusts. Tsis tas li ntawd, cov ntxhia no muaj cov xim hlau nplaum. Cov xim streak ntawm cov pob zeb no yog xiav-dub, thiab nws xau cov ntiv tes. Tsis tas li ntawd, cov ntxhia yog opaque.

Pyrolusite ntxhia tshwm sim nrog manganite, hematite, hausmannite, braunite, thiab hollandite. Cov tshuaj no kuj tshwm sim hauv bogs thiab feem ntau tshwm sim los ntawm kev hloov pauv ntawm manganite. Qhov tseem ceeb tshaj, pyrolusite yog ib qho manganese minerals ntau tshaj plaws.
Muaj ntau yam kev siv pyrolusite, suav nrog kev rho tawm ntawm cov hlau manganese los ntawm kev txo cov ntxhia nrog sodium, magnesium, lossis txhuas, lossis ntawm electrolysis. Cov ntxhia no feem ntau yog siv rau kev tsim khoom ntawm spiegeleisen thiab ferromanganese thiab rau kev tsim ntau cov alloys xws li manganese-bronze alloy. Nws kuj tseem siv tau los ua tus neeg sawv cev oxidizing hauv kev npaj cov roj chlorine.
Psilomelane yog dab tsi?
Psilomelane yog cov ntxhia oxide feem ntau suav nrog barium, potassium thiab manganese oxide tebchaw. Nws tshwm nyob rau hauv cov xim dub thiab muaj grey pyrolusite bands. Cov tshuaj no muaj ib tug monoclinic crystal system thiab conchoidal puas. Tsis tas li ntawd, cov ntxhia no muaj cov xim hlau me me uas muaj qhov pom tsis zoo, thiab cov ntxhia streak xim yog xim av-dub. Cov tshuaj formula rau cov ntxhia no tuaj yeem muab tau raws li Ba(Mn2+)(Mn+4)8 O16(OH)4 Txawm li cas los xij, peb tsis tuaj yeem muab cov tshuaj muaj pes tsawg leeg rau cov khoom no.
Daim duab 02: Psilomelane Mineral
Thaum xav txog qhov tshwm sim ntawm psilomelane, nws yog ib qho tseem ceeb thiab tseem ceeb ore ntawm manganese uas tshwm sim nyob rau hauv tib yam kev mob thiab muaj tib yam kev lag luam daim ntawv thov thiab.
Qhov txawv ntawm Pyrolusite thiab Psilomelane yog dab tsi?
Ob leeg pyrolusite thiab psilomelane yog oxide minerals. Qhov sib txawv tseem ceeb ntawm pyrolusite thiab psilomelane yog tias pyrolusite muaj tetragonal siv lead ua, qhov psilomelane muaj monoclinic siv lead ua kab ke. Tsis tas li ntawd, pyrolusite muaj xim hlau luster, thaum lub luster ntawm psilomelane yog sub-metallic. Lawv muaj cov xim sib txawv thiab; e.g. streak xim ntawm pyrolusite yog xim dub rau xiav-dub xim, thaum lub streak xim ntawm psilomelane yog xim av xim av. Ob qho tib si cov zaub mov no yog opaque hauv lawv cov yam ntxwv kho qhov muag.
Ntxiv mus, pyrolusite yog siv rau kev rho tawm ntawm cov hlau manganese, tsim cov spiegeleisen thiab ferromanganese thiab tsim ntau cov hlau xws li manganese-bronze alloy, thaum psilomelane tsuas yog siv rau kev rho tawm ntawm manganese hlau.
Cov hauv qab no infographic tabulates qhov sib txawv ntawm pyrolusite thiab psilomelane.
Summary – Pyrolusite vs Psilomelane
Pyrolusite thiab psilomelane yog cov ntxhia tseem ceeb ntawm manganese hlau. Txawm li cas los xij, muaj pes tsawg leeg thiab cov qauv ntawm manganese oxide hauv cov tshuaj no txawv ntawm ib leeg. Qhov sib txawv tseem ceeb ntawm pyrolusite thiab psilomelane yog tias pyrolusite muaj tetragonal siv lead ua, qhov psilomelane muaj monoclinic siv lead ua kab ke.
