Qhov sib txawv tseem ceeb ntawm malachite thiab azurite yog malachite muaj xim ntsuab kaj thiab azurite muaj xim xiav azure.
Malachite yog cov ntxhia uas muaj tooj liab carbonate hydroxide muaj cov tshuaj formula Cu2CO3 (OH)2. Azurite yog ib hom carbonate ntxhia uas muaj cov tshuaj formula Cu3(CO3)2(OH)2.
Malachite yog dab tsi?
Malachite yog cov ntxhia uas muaj tooj liab carbonate hydroxide thiab muaj cov tshuaj formula Cu2CO3 (OH)2. Nws zoo nkaus li opaque, ntsuab-banded ntxhia siv lead ua. Cov txheej txheem siv lead ua ntawm cov tshuaj no yog monoclinic, thiab feem ntau, nws tuaj yeem tsim botryoidal, fibrous, lossis stalagmitic masses. Lawv tuaj yeem tsim nyob rau hauv qhov chaw xws li pob txha thiab qhov sib sib zog nqus, qhov chaw hauv av, thiab lwm yam, qhov twg cov kua dej qab zib thiab cov rooj dej tuaj yeem muab cov xwm txheej rau cov nag lossis daus. Nrhiav ib tus neeg muaju ntawm malachite yog qhov nyuaj vim tias nws tshwm sim rau acicular prisms.
Daim duab 01: Malachite Mineral
Malachite los nyob rau hauv qeb ntawm carbonate minerals. Cov tshuaj formula loj ntawm cov ntxhia no yog 221.1 g / mol. Cov cwj pwm siv lead ua feem ntau loj heev, thiab cov muaju yuav tshwm sim li acicular lossis tabular prismatic crystals. Lub cleavage ntawm cov ntxhia yog zoo meej, thiab cov pob txha yog subconchoidal los yog tsis sib xws. Lub hardness ntawm Mohs nplai yog nyob ib ncig ntawm 3.5 - 4.0. Lub luster ntawm malachite tuaj yeem piav qhia tias yog adamantine rau vitreous. Cov ntxhia streak xim ntawm malachite feem ntau yog lub teeb ntsuab. Thaum xav txog cov khoom siv kho qhov muag, cov pob zeb no yog translucent lossis opaque. Nws lub ntiajteb txawj nqus tshwj xeeb yuav nyob ntawm 3.6 txog 4.
Yav dhau los, malachite tau siv los ua cov xim ntxhia hauv cov xim ntsuab. Cov xim no yog me ntsis lightfast thiab rhiab rau acids. Txawm li cas los xij, cov xim ntuj no tau hloov pauv ntau los ntawm cov hluavtaws "verditer" ntsuab pigment. Tsis tas li ntawd, malachite muaj txiaj ntsig zoo rau kev kho kom zoo nkauj hauv tsev cia puav pheej. Tsis tas li ntawd, peb tuaj yeem siv malachite ore los rho tooj liab.
Azurite yog dab tsi?
Azurite yog cov ntxhia uas tshwm hauv cov xim azure-xiav. Nws yog ib hom carbonate ntxhia uas yog mos, sib sib zog nqus-xiav, thiab ua los ntawm tooj liab. Cov tshuaj formula ntawm cov ntxhia no tuaj yeem muab tau raws li Cu3 (CO3) 2 (OH) 2. Crystal system ntawm azurite yog monoclinic, thiab siv lead ua cwj pwm tuaj yeem piav qhia tias loj heev, prismatic stalactitic, thiab tabular. Lub ntxaib ntawm cov ntxhia no tsis tshua muaj, thiab qhov sib cais yog qhov zoo meej. Qhov tawg ntawm cov pob zeb no yog conchoidal, thiab nws yog nkig. Nws hardness tuaj yeem nyob ntawm 3.5 txog 4 ntawm Mohs nplai. Lub luster ntawm azurite tuaj yeem piav qhia tias yog vitreous, thiab cov ntxhia streak xim yog lub teeb xiav. Thaum xav txog cov khoom kho qhov muag ntawm azurite, nws tuaj yeem ua pob tshab lossis translucent.
Daim duab 02: Azurite Mineral
Azurite ntxhia yog siv los ua cov xim xiav nyob rau hauv ancient sij hawm, raws li cov hlaws dai thiab cov hniav nyiaj hniav kub, ua cov pob zeb ornamental, raws li cov pob zeb sau, raws li qhov taw qhia ntawm lub xub ntiag ntawm weathered tooj liab sulfide ores, thiab lwm yam.
Zoo sib xws ntawm Malachite thiab Azurite

Qhov txawv ntawm Malachite thiab Azurite yog dab tsi?
Malachite yog cov khoom siv ntxhia uas muaj tooj liab carbonate hydroxide muaj cov tshuaj formula Cu2CO3 (OH) 2, thaum azurite yog hom carbonate mineral muaj cov tshuaj formula Cu3 (CO3) 2 (OH) 2. Qhov sib txawv tseem ceeb ntawm malachite thiab azurite yog malachite muaj xim ntsuab kaj thiab azurite muaj xim xiav azure.
Cov hauv qab no infographic nthuav tawm qhov sib txawv ntawm malachite thiab azurite hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Malachite vs Azurite
Malachite yog cov khoom siv ntxhia uas muaj tooj liab carbonate hydroxide muaj cov tshuaj formula Cu2CO3(OH)2 thaum azurite yog hom carbonate mineral muaj cov tshuaj formula Cu3(CO3)2(OH)2.
