Budada Tourmaline
Budada Tourmaline waa budada lagu helo si farsamaysan oo loo burburiyo macdanta tourmaline ee asalka ah ka dib markii laga saaro wasakhda.Budada tourmaline ee la warshadeeyay oo la sifeeyay waxay leedahay jiilka anion sare iyo qiiqa infrared fog.Tourmaline waxa kale oo loo yaqaan Tourmaline.Caanaha kiimikada guud ee Tourmaline waa NaR3Al6Si6O18BO33 (OH, F.).4, crystal waxaa iska leh nidaamka trigonal qoyska of qaab-dhismeedka meerto macdanta silicate guud ahaan.Qaaciddada, R waxay u taagan tahay cation bir ah.Marka R uu yahay Fe2 +, waxay samaysaa tourmaline crystal madow.Kiristaalo Tourmaline waa qaab ku dhow tiirar saddex xagal ah, oo leh qaabab crystals oo kala duwan labada daraf.Tiiraryadu waxay leeyihiin xariijimo dhaadheer, oo badanaa ah qaab tiirar, irbado, radial, iyo wadaryo waaweyn.Dhaldhalaalka galaas, dhalaalka resin jabay, si hufan u muuqda.Wax dillaac ah ma jiro.Mohs engegnaanta 7-7.5, cuf-jiid gaar ah 2.98-3.20.Waxaa jira piezoelectricity iyo pyroelectricity.
