Nyob hauv peb lub ntiaj teb no muaj ntau lub pob zeb muaj nuj nqis thiab ib nrab muaj nuj nqis, kev siv uas tsis txwv rau "bruliks" ib leeg.

Txawm li cas los xij, cov lus nug ntawm dab tsi tourmaline qee zaum tshwm sim tom qab mus xyuas ntau yam ntawm cov khw muag khoom kim heev, yog li lawv ua lub luag haujlwm tseem ceeb hauv kev kawm. Los ntawm txoj kev, cia peb saib ze dua ntawm keeb kwm thiab cov yam ntxwv ntawm cov khoom no.

Kev piav qhia

Yog li, dab tsi yog tourmaline? Nws yog ib qho ntxhia los ntawm chav kawm ntawm lub nplhaib silicates. Ntau precisely, ib pab pawg neeg ntawm minerals, txij li thaum ntawm lawv muaj ntau yam uas yuav luag opposite nyob rau hauv lawv cov khoom. Kev hais lus ntau dua, cov tshuaj no tshwm sim hauv qhov xwm txheej ntawm ntau lub isomorphic series.

Ntawm lub plawv ntawm kev zoo nkauj zoo nkauj ntawm tourmaline crystals yog silicon oxide, uas crystallizes nyob rau hauv ib tug trigonal syngony. Lawv cov xim tuaj yeem sib txawv ntawm cov xim dub mus rau cov pob tshab kiag li.

Qhov saum npoo feem ntau zoo li iav (vim cov yam ntxwv ci ntsa iab), tab sis nws zoo nkauj dua rau qhov kov, vim nws muaj cov qauv "silky". Vim li no, cov lus nug ntawm dab tsi tourmaline yog feem ntau teb tias nws yog ib daim ntawm cov hniav nyiaj hniav kub. Lawv yog cov tawv nqaij tawv heev, ua los ntawm cov ntxhia no.

Jewellers tshwj xeeb tshaj yog txaus siab rau ntau yam polychrome. Qhov no yog lub npe ntawm tourmaline specimens, nyob rau hauv ib tug siv lead ua ntawm uas ob peb xim zones tau ua ke ib zaug. Tsis tas li ntawd, nws qhov txawv txav yog hemimorphism, thaum lub ntsej muag sib txawv ntawm cov siv lead ua raug txiav nyob rau hauv ib txoj kev sib txawv kiag li.

Daim ntawv thov

Tus nqi ntawm tourmalines yog tias lawv muaj pyro- thiab piezoelectric zoo, uas yog vim li cas lawv tau siv dav hauv ntau yam lag luam. Rau lub hom phiaj no, cov xim tsis muaj xim zoo nkauj feem ntau siv, uas tsis muaj qhov tsis xws luag.

Txawm li cas los xij, qhov no ntau dua rau cov khoom pheej yig, txij li opaque tourmaline ntau dua nyob rau hauv qhov xwm txheej, thiab yog li muab tus nqi qis rau cov khoom siv uas nws siv.

Lub piezoelectric zog ntawm lub pob zeb muaj feem xyuam rau qhov tseeb tias nws lub ntsej muag rov qab tuaj yeem khaws cov nqi ntawm cov polarities opposite. Qhov no yog vim qhov hemimorphism tau piav qhia saum toj no (uas tsis tshua muaj nyob hauv lwm cov ntaub ntawv crystalline). Nws tau nquag siv hauv hluav taws xob, thiab cov khoom siv lead ua loj tshaj plaws tshwj xeeb tshaj yog hais.

Yuav luag txhua hom tourmaline tuaj yeem siv txawm tias siv cov cuab yeej kho mob nyuaj. Ua ke nrog nws cov nqi qis, qhov no qhib qhov kev cia siab dav heev. Thiab cov kws kho mob tau tshawb pom ntev nws lub peev xwm hauv huab cua ionization, uas yog vim tib lub piezoelectricpeev xwm.

Los ntawm txoj kev, hais txog nws cov khoom muaj nqis ib nrab. Raws li cov pob zeb diamond, kev faib cov pob zeb rau hauv "lub pov haum" thiab "tshwj xeeb" feem ntau yog nyob ntawm lawv qhov pom tseeb thiab pom.

Polychrome ntau yam yog qhov xav tau rau cov hniav nyiaj hniav kub, thaum cov pob tshab zoo meej tau hais los ntawm cov kws tshaj lij.

Tam sim no koj paub tseeb tias tourmaline yog dab tsi.
