Gems Dabiiciga ah Wareega Garnet Jaalle 3.0mm
Faahfaahinta Alaabta:
Garnet, oo loo yaqaan ziyawu ama ziyawu ee Shiinaha qadiimiga ah, waa koox macdan ah oo loo isticmaali jiray dhagax-dhagax iyo abrasives xilligii naxaasta.Garnetka guud waa casaan.Garnet English "garnet" waxay ka timid Laatiinka "granatus" (midho), kaas oo laga yaabo inuu ka yimaado "Punica granatum" (rummaan).Waa geed leh iniin cas, qaabkeeda, cabbirkeeda iyo midabkeeduba waxay la mid yihiin kirismaska garnet qaarkood.
Garnets-ka caadiga ah waxaa loo kala saaraa lix nooc iyadoo loo eegayo ka koobnaantooda kiimikaad, kuwaas oo kala ah, pyrope, almandine, spessartite, andradite, Grossular, iyo kala duwanaanshiyaha waa tsavorite, Hessonite, iyo uvarovite.Garnet wuxuu sameeyaa laba taxane oo xal adag: (1) birta garnet birta aluminium garnet manganese aluminium garnet iyo;(2) Calcium chromium garnet calcium aluminium garnet calcium birta garnet.Garnet aduunka wax darajo ah kuma laha.Waxa loogu yeero "A" waxaa lagu kala soocaa iyadoo loo eegayo aragtida shakhsi ahaaneed.Isla garnetka ayaa sheegi kara tirooyin kala duwan oo gacmo kala duwan ku jira.[1]

Qaybaha ugu muhiimsan:
Halabuurka kiimikada ee garnet waa mid aad u adag, iyo walxo kala duwan ayaa sameeya isku-dhafka kala duwan, sidaas darteed taxane qoysaska garnet leh oo isku mid ah iyo muuqaal la mid ah ayaa la sameeyay.Qaaciddada guud waa a3b2 (SiO4) 3, halkaas oo ay ka dhigan tahay curiyeyaasha kala duwan (kalsiyum, magnesium, iron, manganese, iwm.) B waxay ka dhigan tahay curiyeyaasha trivalent (aluminium, iron, chromium, titanium, vanadium, zirconium, iwm.).Caadi ahaan waa magnesia aluminium garnet, kaas oo ka kooban chromium iyo xubno bir ah waana dhiig casaan, casaan guduudan iyo maroon;Midda labaad waa birta aluminium garnet, taas oo ah casaan guduudan.Karistanka leh horumarinta ka mid noqoshada ayaa soo saari karta iftiinka xiddigaha ee afar-geesoodka ah;Magnesium birta garnet waa iftiin casaan ah oo casaan ah, taas oo ah mid ka mid ah noocyada muhiimka ah ee dhagaxyada garnet;Calcium aluminium garnet waxaa ku jira raad raac vanadium iyo ion chromium, sidaas darteed waxaa loogu yeeraa noocyo cagaaran oo heer sare ah.
Iyadoo ay ugu wacan tahay raadiyaha la midka ah ee cations trivalent, beddelka isomorphic waa sahlan tahay in uu dhexdooda ka dhaco.Noocyada kala duwan ayaa kala duwan.Sababtoo ah CA waxay leedahay radius ka weyn mg, Fe iyo Mn plasma, way adagtahay in lagu beddelo isomorphism.Sidaa darteed, garnet waxaa badanaa loo qaybiyaa laba taxane:
(1) Taxanaha aluminium: mg3al2 (SiO4) 3 － fe3al2 (SiO4) 3 － mn3al2 (SiO4) 3
Waa taxane isomorphic ah oo ka kooban cations kala duwan sida Mg, Fe iyo Mn oo leh radius yar yar iyo cations trivalent sida al.Noocyada caadiga ah waxaa ka mid ah magnesium aluminium garnet, aluminium aluminium garnet iyo manganese aluminium garnet.
(2)Taxane kaalshiyam: ca3al2 (SiO4) 3 － Ca3Fe2 (SiO4) 3 － ca3cr2 (SiO4) 3
(3) Waa taxane isomorphic ah oo ay maamusho divalent cation CA oo leh radius weyn.Kuwa caadiga ah waa calcium aluminium garnet, calcium iron garnet iyo calcium chromium garnet.Intaa waxaa dheer, xarkaha garnet-yada qaarkood ayaa sidoo kale ku xiran ions OH si ay u sameeyaan noocyo biyo-biyood ah, sida biyaha calcium aluminium garnet.Sababtoo ah beddelka ballaaran ee isomorphic, isku dhafka kiimikada ee garnet badanaa waa mid aad u adag.Halabuurka garnet ee dabeecadda badanaa waa xaaladda kala-guurka ee beddelka isomorphic, waxaana jira garnets yar oo leh qaybaha ugu dambeeya ee xubnaha.[2]
