Yuav ua li cas yog tourmaline, thiab qhov twg yog nws siv?

Nyob rau hauv lub depths ntawm lub ntiaj teb no muaj ib tug lossis loj npaum li ntawm ob qho tib si muaj nuj nqis heev thiab semi-precious pob zeb, siv cov uas yog tsis tas rau xwb "bryulikami".

Txawm li cas los, cov lus nug ntawm yog dab tsi tourmaline, tej zaum nws tshwm sim tom qab mus xyuas txhua hom hniav nyiaj hniav kub khw muag khoom noj, yog li ntawd lawv ua si ib tug tseem ceeb luag hauj lwm nyob rau hauv cov kev kawm ua si. Los ntawm txoj kev, saib lub hauv paus pib thiab cov yam ntxwv ntawm cov khoom no rau hauv kom meej.

piav qhia

Yog li ntawd, yog dab tsi tourmaline? Nws yog ib tug mineral los ntawm cov chav kawm ntawv nplhaib silicates. Dua, cov pab pawg neeg ntawm cov zaub mov, vim hais tias nyob rau hauv lawv muaj cov hom yuav luag rov qab nyob rau hauv nws cov khoom. Hais lus ntau technically, ib yam khoom uas pom lawm nyob rau hauv daim ntawv ntawm ob peb isomorphic series.

Lwm amazing tourmaline muaju kev zoo nkauj dag silicon oxide crystallizes nyob rau hauv lub trigonal system. Lawv xim yuav sib txawv ntawm dub mus lig tshab ntau ntau yam.

Lub nto ntawm cov iav ntau ntaqwm (vim yam ntxwv gloss), tab sis ntau nicer mus kov nws, vim hais tias nws muaj ib yam ntawm cov "ntaug" kev ntxhib los mos. Vim li no, cov nqe lus nug ntawm yog dab tsi tourmaline, feem ntau tau teb hais tias nws yog ib daim ntawm hniav nyiaj hniav kub. Lawv tabtom ua los ntawm cov mineral, nws yog tsis tshua muaj ua rau ntawm daim tawv nqaij.

Jewelers tshwj xeeb kev txaus siab rau cov polychromatic ntau yam. Yog li ntawd hu ua tourmaline nrws nyob rau hauv ib nti uas combines ntau xim aav. Nyob rau hauv tas li ntawd, nws txawv feature yog gemimorfizm thaum bounding lub opposite ntsej muag ntawm tus siv lead ua txawv heev.

daim ntawv thov

Tus nqi tourmaline yog hais tias lawv muaj ib tug pyroelectric thiab piezoelectric zog, vim uas yog lug siv nyob rau hauv ntau yam industries. Rau lub hom phiaj no, high-zoo tsis muaj kob muaju yog feem ntau siv, uas yog free uas tsis xws luag.

Txawm li cas los, nws yog ntau npaum li cas feem ntau los txog rau pheej yig khoom, raws li opaque tourmaline yog ntau npaum li cas ntau nyob rau hauv, thiab yog li muaj ib tug uas tsis muaj nqi ntawm cov khoom nyob rau hauv uas nws yog thov.

Lub piezoelectric thaj chaw ntawm lub pob zeb yog txuam nrog rau qhov tseeb hais tias nws cov lus rov ntsej muag heteropolar nqi yuav noog. Qhov no yog vim gemimorfizma (uas nyob rau hauv lwm yam crystalline ntaub ntawv yog tsawg) tau piav saum toj no. Nws yog kev koom siv nyob rau hauv electronics, nrog cov coob muaju tshwj xeeb uas muaj npe.

Zoo ib yam ntawm cov tourmaline yuav siv tau txawm nyob rau hauv lub complex kho mob cov khoom. Coupled nrog nws me me nqi nws muab ib tug sab heev zeem muag. Thiab cov kws kho mob tau ntev sab nws tej zaum nyob rau hauv lub ionization ntawm huab cua, uas yog tshwm sim los ntawm tib lub piezoelectric zog.

Incidentally, kev xav txog nws semi-precious zog. Raws li nyob rau hauv cov ntaub ntawv ntawm cov pob zeb diamond, lub tsev ntawm pob zeb nyob rau hauv lub "hniav nyiaj hniav kub" thiab "kev" yog lom zem ntau raws li nyob rau hauv ob qho tib si lawv transparency thiab tsos.

Polychrome hom yog nyob rau hauv siab thov rau hniav nyiaj hniav kub, thaum txig pob tshab muaju teev tseg hom kev kawm.

Tam sim no koj paub raws nraim li cas yog tourmaline.
