ʻO Tourmaline ka inoa maʻamau o nā minelala hui tourmaline. He paʻakikī kona ʻano kemika. He ʻano apo ia o ka minelala silicate i hōʻailona ʻia e ka boron e loaʻa ana ka alumini, sodium, hao, magnesium a me ka lithium. [1] ʻO ka paʻakikī o ka tourmaline he 7-7.5 maʻamau, a he ʻokoʻa iki kona density me nā ʻano like ʻole. E nānā i ka papa ma lalo no nā kikoʻī. Ua ʻike ʻia ʻo Tourmaline ʻo tourmaline, tourmaline, etc.

Loaʻa i ka Tourmaline nā waiwai kūikawā e like me ka piezoelectricity, pyroelectricity, ka radiation infrared mamao a me ka hoʻokuʻu ʻana o ka ion maikaʻi ʻole. Hiki ke hoʻohui ʻia me nā mea ʻē aʻe ma o nā ʻano kino a kemika paha e hana i nā ʻano mea hana like ʻole, i hoʻohana ʻia i ka palekana o ke kaiapuni, nā mea uila, nā lāʻau lapaʻau, ka ʻoihana kemika, ka ʻoihana māmā, nā mea kūkulu hale a me nā ʻoihana ʻē aʻe.

ʻO Tourmaline ʻāwili
ʻO ke kristal hoʻokahi a i ʻole ke kristal micro i ʻeli pololei ʻia mai ka lua e hoʻopili ʻia i loko o kahi nui o ka tourmaline nui.
