I-Tourmaline yigama elijwayelekile lamaminerali eqembu le-tourmaline. Ukwakheka kwayo kwamakhemikhali kuyinkimbinkimbi kakhulu. Iyiminerali yesakhiwo sendandatho esinobucwebe ebonakala nge-boron equkethe i-aluminium, i-sodium, i-iron, i-magnesium kanye ne-lithium. [1] Ubulukhuni be-tourmaline buvame ukuba ngu-7-7.5, futhi ubuningi bayo buhlukile kancane ngezinhlobo ezahlukene. Bheka ithebula elingezansi ukuthola imininingwane. I-Tourmaline yaziwa nangokuthi i-tourmaline, i-tourmaline, njll.

I-Tourmaline inezakhiwo ezihlukile njenge-piezoelectricity, i-pyroelectricity, imisebe ye-infrared ekude kanye nokukhululwa kwe-ion engemihle. Ingahlanganiswa nezinye izinto ngezindlela zomzimba noma zamakhemikhali ukukhiqiza izinto ezahlukahlukene ezisebenzayo, ezisetshenziswa ekuvikelweni kwemvelo, kuma-elekthronikhi, kwezokwelapha, embonini yamakhemikhali, embonini yokukhanya, ezintweni zokwakha nakwezinye izinkambu.

I-Tourmaline ebukhali
Ikristalu elilodwa noma ikristalu elincane elimbiwa ngqo kuma-agglomerate emayini libe yivolumu ethile ye-tourmaline enkulu.
