Natrual Gems Yellow Garnet Round 3.0mm

Huahana Huahana:

ʻO Garnet, i kapa ʻia ʻo ziyawu a i ʻole ziyawu ma Kina kahiko, he hui o nā mineral i hoʻohana ʻia e like me nā pōhaku a me nā abrasives i ka makahiki keleawe.He ʻulaʻula ka garnet maʻamau.ʻO Garnet English "garnet" mai ka Latin "granatus" (grain), a mai ka "Punica granatum" (pomegranate).He mea kanu ia me nā ʻanoʻano ʻulaʻula, a ʻo kona ʻano, ka nui a me kona waihoʻoluʻu e like me kekahi mau kristal garnet.
Hoʻokaʻawale ʻia nā garnets maʻamau i ʻeono mau ʻano e like me kā lākou haku mele, ʻo ia hoʻi, pyrope, almandine, spessartite, andradite, Grossular, a ʻo nā ʻano like ʻole he tsavorite, Hessonite, a me uvarovite.Hoʻokumu ʻia ʻo Garnet i ʻelua pūʻulu hoʻonā paʻa: (1) ʻulaʻula ʻulaʻula hao alumini ʻulaʻula manganese alumini garnet a me;(2) Calcium chromium garnet calcium alumina garnet calcium hao garnet.ʻAʻohe kūlana o Garnet ma ka honua.Hoʻokaʻawale ʻia nā mea i kapa ʻia ʻo "A's" e like me nā manaʻo pilikino.Hiki i ka garnet hoʻokahi ke haʻi i nā helu like ʻole ma nā lima like ʻole.[1]

Nā mea nui:

He paʻakikī ke ʻano kemika o ka garnet, a ua hoʻokumu ʻia nā mea like ʻole i nā hui like ʻole, no laila ua hoʻokumu ʻia kahi pūʻulu o nā ʻohana garnet me ke ʻano like a me ke kiʻi.ʻO ke kumu maʻamau he a3b2 (SiO4) 3, kahi e hōʻike ai i nā mea divalent (calcium, magnesium, iron, manganese, etc.) a ʻo B e hōʻike ana i nā mea trivalent (aluminum, hao, chromium, titanium, vanadium, zirconium, etc.).ʻO ka mea maʻamau ka magnesia alumini garnet, aia nā mea chromium a me nā mea hao a he ʻulaʻula koko, ʻulaʻula ʻulaʻula a me ka maroon;ʻO ka lua, he hao alumini garnet, he ʻulaʻula ʻulaʻula.Hiki i ke aniani me ka hoʻomohala hoʻokomo ke kālai ʻia i ke kukui hōkū ʻehā;ʻO ka Magnesium iron garnet he ʻulaʻula ʻulaʻula rose poni, ʻo ia kekahi o nā ʻano mea nui o nā pōhaku garnet;Loaʻa ka vanadium a me nā ion chromium ka calcium alumini garnet, no laila ua kapa ʻia ʻo ia he ʻano ʻōmaʻomaʻo kiʻekiʻe.
Ma muli o ka radius like o nā cations trivalent, maʻalahi ka hoʻololi isomorphic ma waena o lākou.ʻOkoʻa nā cation divalent.No ka mea he ʻoi aku ka nui o ka radius CA ma mua o mg, Fe a me Mn plasma, paʻakikī ke hoʻololi iā ia me ka isomorphism.No laila, ua māhele ʻia ka garnet i ʻelua pūʻulu:
(1) Moʻo Aluminum: mg3al2 (SiO4) 3 － fe3al2 (SiO4) 3 － mn3al2 (SiO4) 3
He moʻo isomorphic i haku ʻia me nā cations divalent e like me Mg, Fe a me Mn me nā radius liʻiliʻi a me nā cations trivalent e like me al.ʻO nā ʻano like like me ka magnesium alumini garnet, ka hao alumini garnet a me ka manganese alumini garnet.
(2) Moʻo kalakala: ca3al2 (SiO4) 3 － Ca3Fe2 (SiO4) 3 － ca3cr2 (SiO4) 3
(3) He moʻo isomorphic i hoʻomalu ʻia e divalent cation CA me ka radius nui.ʻO nā mea maʻamau he calcium alumini garnet, calcium hao garnet a me calcium chromium garnet.Eia kekahi, ua hoʻopili pū ʻia ka lattice o kekahi mau garnets me nā ion OH e hana i nā subspecies aqueous, e like me ka wai calcium alumini garnet.Ma muli o ka hoʻololi ʻana o ka isomorphic nui, ʻoi aku ka paʻakikī o ka hui ʻana o ka garnet.ʻO ke ʻano o ka garnet ma ke ʻano he mea maʻamau ke kūlana hoʻololi o ka hoʻololi isomorphic, a he liʻiliʻi nā garnets me nā ʻāpana lālā hope.[2]
