Amagugu Emvelo Ephuzi Garnet Round 3.0mm
Imininingwane Yomkhiqizo:
I-Garnet, ebizwa ngokuthi ziyawu noma ziyawu eShayina yasendulo, iqoqo lamaminerali asetshenziswe njengamatshe ayigugu kanye nama-abrasives esikhathini sethusi.I-garnet evamile ibomvu.I-Garnet English elithi “garnet” livela kwelesiLatini elithi “granatus” (okusanhlamvu), elingase livele kwelithi “Punica granatum” (ipomegranati).Kuyisitshalo esinembewu ebomvu, futhi ukuma kwaso, ubukhulu nombala kufana namanye amakristalu e-garnet.
Ama-garnet ajwayelekile ahlukaniswa abe yizinhlobo eziyisithupha ngokuya ngamakhemikhali awo, okungukuthi, i-pyrope, i-almandine, i-spessartite, i-andradite, i-Grossular, futhi okuhlukile yi-tsavorite, i-Hessonite, ne-uvarovite.I-Garnet yakha uchungechunge lwezixazululo ezimbili eziqinile: (1) i-garnet ebomvu yensimbi ye-aluminium garnet manganese aluminium garnet kanye;(2) I-Calcium chromium garnet i-calcium aluminium garnet i-calcium iron garnet.I-Garnet ayinawo umehluko webanga emhlabeni.Okubizwa ngokuthi “o-A” bahlukaniswa ngokwemibono yomuntu.I-garnet efanayo ingasho izinombolo ezihlukene ezandleni ezihlukene.[1]

Izingxenye eziyinhloko:
Ukwakheka kwamakhemikhali e-garnet kuyinkimbinkimbi, futhi izakhi ezihlukene zakha inhlanganisela ehlukene, ngakho-ke uchungechunge lwemindeni ye-garnet enokwakheka okufanayo nesithombe kwakheka.Ifomula evamile ithi a3b2 (SiO4) 3, lapho u-a emelela izakhi ze-divalent (i-calcium, i-magnesium, insimbi, i-manganese, njll.) kanye no-B imelela izakhi ezintathu (i-aluminium, insimbi, i-chromium, i-titanium, i-vanadium, i-zirconium, njll.).Okujwayelekile i-magnesia aluminium garnet, equkethe i-chromium nezakhi zensimbi futhi ibomvu ngegazi, i-purplish ebomvu ne-maroon;Eyesibili i-iron aluminium garnet, ebomvu ngokunsomi.Ikristalu enokuthuthukiswa kokufakwayo ingaqopha ukukhanya kwenkanyezi okunezinhlangothi ezine;I-Magnesium iron garnet iwumbala obomvu we-rose onsomi, okungenye yezinhlobo ezibalulekile zamatshe ayigugu e-garnet;I-calcium aluminium garnet iqukethe i-trace vanadium ne-chromium ions, ngakho ibizwa ngokuthi uhlobo oluluhlaza olusezingeni eliphezulu.
Ngenxa yobubanzi obufanayo be-trivalent cations, ukushintshwa kwe-isomorphic kulula ukwenzeka phakathi kwawo.Ama-Divalent cations ahlukile.Ngenxa yokuthi i-CA ine-radius enkulu kune-mg, i-Fe ne-Mn plasma, kunzima ukuyibuyisela nge-isomorphism.Ngakho-ke, i-garnet ivame ukuhlukaniswa ngochungechunge olubili:
(1) Uchungechunge lwe-Aluminium: mg3al2 (SiO4) 3 - fe3al2 (SiO4) 3 - mn3al2 (SiO4) 3
Kuwuchungechunge lwe-isomorphic olwakhiwe ngama-divalent cations afana ne-Mg, Fe kanye ne-Mn ene-radius encane kanye nama-trivalent cations afana ne-al.Izinhlobo ezijwayelekile zihlanganisa i-magnesium aluminium garnet, i-iron aluminium garnet ne-manganese aluminium garnet.
(2)Uchungechunge lweCalcium: ca3al2 (SiO4) 3 - Ca3Fe2 (SiO4) 3 - ca3cr2 (SiO4) 3
(3)Iwuchungechunge lwe-isomorphic olubuswa yi-divalent cation CA ene-radius enkulu.Ezivamile i-calcium aluminium garnet, i-calcium iron garnet kanye ne-calcium chromium garnet.Ngaphezu kwalokho, i-lattice yamanye ama-garnet nayo ixhunywe nama-OH ions ukuze kwakhe i-subspecies enamanzi, njenge-water calcium aluminium garnet.Ngenxa yokushintshwa okubanzi kwe-isomorphic, ukwakheka kwamakhemikhali e-garnet ngokuvamile kuyinkimbinkimbi kakhulu.Ukwakhiwa kwe-garnet emvelweni ngokuvamile kuyisimo soguquko sokushintshwa kwe-isomorphic, futhi kukhona ama-garnet ambalwa anezingxenye zamalungu ekugcineni.[2]
