ʻO ka pauka Tourmaline
ʻO ka pauka Tourmaline ka pauka i loaʻa ma ka ʻokiʻoki ʻana i ka ʻaila tourmaline mua ma hope o ka wehe ʻana i nā haumia.ʻO ka pauka tourmaline i hoʻomaʻemaʻe ʻia a hoʻomaʻemaʻe ʻia ʻoi aku ka kiʻekiʻe o ka anion generation a me ka emissivity infrared mamao.Ua kapa ʻia ʻo Tourmaline.NaR3Al6Si6O18BO33 (OH, F.).4, no ka kristal ka ʻohana trigonal system o cyclic structure silicate minerals ma ka laulā.Ma ke kumu hoʻohālike, hōʻike ʻo R i kahi cation metala.Inā ʻo R ka Fe2 +, hana ia i ka tourmaline aniani ʻeleʻele.ʻO nā kristal Tourmaline i ke ʻano o nā kolamu kokoke ʻekolu, me nā ʻano aniani like ʻole ma nā kihi ʻelua.Loaʻa i nā kolamu nā kaha lōʻihi, pinepine i ke ʻano o nā kolamu, nā nila, nā radials, a me nā hui nui.ʻAiani aniani, ʻōniʻoniʻo resin haʻihaʻi, translucent a ʻalohilohi.ʻAʻohe māhele.ʻO ka paʻakikī o Mohs 7-7.5, gravity kiko'ī 2.98-3.20.Aia ka piezoelectricity a me ka pyroelectricity.
