Lub Cev Khoom Ntawm Quartz Pob Zeb

(1) Siab.
(2) Nws muaj cov khoom siv thermoelectric.
(3) Refractive index 1.533~1.541, birefringence sib txawv 0.009, dispersion 0.013.
(4) Quartz muaj zog piezoelectric khoom, uas txhais tau hais tias sparks yog generated thaum ntaus thiab rubbed nrog quab yuam, uas yog txoj kev siv flint rau ignite.
(5) Cov feem ntau suav nrog hauv quartz yog: Cov plaub hau siv lead ua - feem ntau yog rutile. Nyom nkag mus siv lead ua - feem ntau yog tourmaline; Dej gall siv lead ua - muaj cov kua hauv cov quartz; Blue quartz - muaj koob zoo li lub teeb xiav hematite; Mis quartz - turbidity tshwm sim los ntawm nplua dej pores; Ntsuab quartz - muaj xws li phaj zoo li los yog fragmented chlorite, qee zaum ntsuab koob zoo li actinolite; Aventurine - quartzite muaj cov xim ntsuab lossis xim av xim av mica flakes sab hauv, tseem hu ua ci ntsa iab quartz, feem ntau hu ua Dongling pob zeb. Feem ntau haus luam yeeb dub mus rau tsaus xim av smoky crystals yog vim lawv cov ntsiab lus siab ntawm radioactive uranium thiab thorium ntsiab.
