Tourmaline yog lub npe dav dav ntawm tourmaline pawg minerals.Nws cov tshuaj muaj pes tsawg leeg yog qhov nyuaj.Nws yog ib lub nplhaib qauv silicate ntxhia cim los ntawm boron uas muaj txhuas, sodium, hlau, magnesium thiab lithium.[1] Lub hardness ntawm tourmaline feem ntau yog 7-7.5, thiab nws qhov ntom yog me ntsis txawv nrog ntau hom.Saib cov lus hauv qab no kom paub meej.Tourmaline tseem hu ua tourmaline, tourmaline, thiab lwm yam.
Tourmaline muaj cov khoom tshwj xeeb xws li piezoelectricity, pyroelectricity, far-infrared tawg thiab tsis zoo ion tso tawm.Nws tuaj yeem sib xyaw nrog lwm cov ntaub ntawv los ntawm kev siv lub cev lossis tshuaj lom neeg los tsim ntau yam khoom siv, uas yog siv rau hauv kev tiv thaiv ib puag ncig, hluav taws xob, tshuaj, tshuaj lom neeg kev lag luam, kev lag luam teeb, khoom siv hauv tsev thiab lwm yam.
