LiNbO₃ lagama helo dabiiciga sida macdanta dabiiciga ah. Qaab dhismeedka crystals ee lithium niobate (LN) crystals waxaa markii ugu horeysay ka warbixiyay Zachariasen 1928. 1955 Lapitskii iyo Simanov waxay siiyeen qiyaasaha xajmiyada ee nidaamyada lix geesoodka iyo trigonal ee crystal LN by X-ray falanqaynta diffraction budada. Sannadkii 1958-kii, Reisman iyo Holtzberg waxay siiyeen qaybta hoose ee Li₂O-Nb₂O₅ by falanqaynta kulaylka, X-ray falanqaynta diffraction iyo cabbir cufnaanta.

Jaantuska wajiga ayaa muujinaya in Li₃NbO₄, LiNbO₃, LiNb₃O₈ iyo Li₂Nb₂₈O₇₁ dhammaan waxaa laga samayn karaa Li₂O-Nb₂O₅. Sababo la xiriira diyaarinta crystal iyo sifooyinka alaabta, kaliya LiNbO₃ si weyn ayaa loo dersay oo loo dabaqay. Marka loo eego qaanuunka guud ee magaca kiimikada, LithiumNiobate waa inay noqotaa Li₃NbO₄, iyo LiNbO₃ waa in loogu yeeraa lithium Metaniobate. Marxaladda hore, LiNbO₃ runtii waxaa loo yaqaan 'lithium' Metaniobate crystal, laakiin sababtoo ah crystals LN leh sadex kale oo adags si weyn looma baranin, hadda LiNbo₃ waa ku dhawaad ​​hadda lama wicin Lithium Metniobate, laakiin si weyn ayaa loo yaqaan Lithium Niobate.

Karistaanka tayada sare leh ee LiNbO3 (LN) ee ay samaysay WISPTIC.com

Barta wada dhalaalka ee dareeraha iyo qaybaha adag ee kiristaalo LN kuma waafaqsana saamigeeda stoichiometric. Kiristaalo tayo sare leh oo leh qaybo isku mid ah oo madax iyo dabo ah ayaa si fudud loo kori karaa iyadoo la adeegsanayo habka crystallization kaliya marka walxaha isku midka ah ee heerka adag iyo heerka dareeraha la isticmaalo. Sidaa darteed, kiristaalo LN oo leh hanti wanaagsan oo dareere eutectic ah oo u dhigma ayaa si weyn loo isticmaalay. Kiristaalo LN sida caadiga ah aan la sheegin waxay tixraacaan kuwa isku mid ah, iyo waxa ku jira lithium ([Li]/[Li+Nb]) waa qiyaastii 48.6%. Maqnaanshaha tiro badan oo lithium ions ah ee LN crystal waxay keenaysaa tiro badan oo cillado ah, kuwaas oo leh laba saameyn oo muhiim ah: Marka hore, waxay saamaysaa sifooyinka LN crystal; Marka labaad, cilladaha lattice waxay bixiyaan saldhig muhiim ah oo loogu talagalay injineernimada doping ee LN crystal, taas oo si wax ku ool ah u habeyn karta waxqabadka crystal iyada oo loo marayo nidaaminta qaybaha crystal, doping iyo valence control ee walxaha doped, taas oo sidoo kale ah mid ka mid ah sababaha muhiimka ah ee dareenka crystal LN.

Si ka duwan crystal-ka caadiga ah ee LN, waxaa jira “u dhow stoichiometric LN crystal" kuwaas oo [Li]/[Nb] ku saabsan yahay doping-stoichiometric dhow, sidaa darteed si weyn ayaa loo darsay. Si kastaba ha ahaatee, maadaama stoichiometric LN crystal-ku uusan ahayn eutectic leh qaybo adag iyo dareere, way adagtahay in la diyaariyo hal crystal oo tayo sare leh Czochralski caadiga ah. habka. Sidaa darteed waxaa weli jira shaqooyin badan oo loo baahan yahay in la sameeyo si loogu diyaariyo tayada sare iyo kharash-ool ee u dhow-stoichiometric LN crystal si loo isticmaalo wax ku ool ah.
