Anatase

E kūʻai i ka anatase kūlohelohe i kā mākou hale kūʻai


ʻO Anatase kahi minerable mineral form a titanium dioxide. Loaʻa ka minuke ma nā puka kūlohelohe e like me ke ʻano ʻeleʻele uliuli, ʻoiai ʻo ka ʻeke maʻa ʻole he ʻulaʻula ʻole a keʻokeʻo paha. ʻElua mau mea helehelena maʻamau e ulu mai nei no ka TiO2 i ʻike ʻia, he brookite a me rutile.

Loaʻa ʻia ka Anatase ma muli o ka liʻiliʻi, kaawale a me nā mea i hoʻomohala ʻia, a like hoʻi me ka rutile thermodynamically paʻa, ka crystallizes i ka pā tetragonal. Hoʻopili ʻia ka pōhaku kiʻekiʻe i nā kauwela a me nā pali, me ka rutile ʻo ia ka polymorph equilibrium. Eia nō naʻe, ʻo ka anatase ka mana mua o ka mīkini titanium hoʻoneʻe e hana i nā ʻōnaehana nui, ma muli o kona ikehu haʻahaʻa, me ka loli e pili ana i ka rutile i nā manawa kiʻekiʻe. ʻOiai ke ʻano o ka symmetry like no nā phase anatase a me nā rutile, ʻaʻohe pilina ma waena o nā manamana interfacial o nā minima ʻelua, koe wale nō ma kahi o ka prism-zone o 45 ° a 90 °. ʻO ka ka pulu maʻamau o ke anase, pili me ka maka o nā ʻāpana kūpono, aia kahi kihi ma ke aniani o ka palena o 82 ° 9 ′, ke kihi o ka rutile e pili ana i ka 56 ° 52½ '. Ma muli o kēia pala

he aniani maʻa

Hiki ke hoʻokaʻawale ʻia ʻelua mauʻano ulu o ka crystals kristal. ʻO nā mea maʻamau ka maʻalahi e like me ka piramide papalua maʻalahi maʻalahi me ka indigo-blue i ka ʻeleʻele ʻeleʻele a me ka luster steely. Nui nā crystals o kēia ʻano ma Le Bourg-dʻOisans ma Dauphiné, kahi i pili ai iā lākou me ka pōhaku-crystal, feldspar, a me ka maha o nā crevice i ka granite a me mica-schist. ʻO nā aniani like like, akā naʻe o ka nui o ka mikroskopika, ke pālahalaha nui ʻia i nā pōhaku sedimentary, e like me ke aniani, ke kāʻei, a me nā maʻa, kahi e hoʻokaʻawale ʻia ai lākou me ka holoi ʻana i nā mea māmā o nā papa poloka. ʻO ka mokulele o ka anatase ka ipu kūmole thermodynamically paʻa a no laila ke kiko ākea ākea i loko o ka ʻano natural natural synthetic.

He mau pyramidal mau hiʻohiʻona no nā ʻano lua o nā ʻano he lua, a he mau ʻanuʻu a i ʻole kekahi prismatic i loko o ke ʻano, ʻo ka kala ka melemele i ka brown. Kahi like ʻole nā ​​crystals e like me xenotime i ka helehelena a, aia nō no ka manawa lōʻihi i manaʻo ʻia he pili ʻole ia me kēia ʻano ʻano, ʻo ka inoa aloha maikaʻi e hoʻohana ʻia iā lākou. Hoʻokaʻa ʻia lākou ma nā paia o nā crevices i nā gneisses o nā Alps, ka Binnenthal kokoke kokoke iā Brig i canton Valais, Switzerland, he kamaʻāina kaulana. ʻO ka hele maoli ʻana i nā pseudomorphs o ka rutile ma hope o ka anatase e ʻike ʻia.
