Daaqadda Qaybta Indhaha ee Qaabaysan ee Safayr

Sharaxaad Gaaban:

Qaybtan qaabaysan ee safayr waa qayb muraayadeed oo waxqabad sare leh oo laga sameeyay safayr keli ah (Al₂O₃), oo si gaar ah loogu talagalay codsiyada indhaha ee horumarsan oo u baahan cimri dherer, saxnaan, iyo hufnaan heer sare ah. Substrate-ka qaabaysan ee safayr wuxuu muujiyaa xoog farsamo oo heer sare ah iyo hufnaan aragtiyeed, taasoo ka dhigaysa mid ku habboon deegaannada ay walxaha galaaska caadiga ahi aysan u adkeysan karin xaaladaha daran.

Sifooyinka iyo Faa'iidooyinka Agabka

Qaybta indhaha ee qaab safayr ah waxay leedahay naqshad leydi ah oo gaar ah oo leh godad sax ah, oo loogu talagalay in lagu daro nidaamyada indhaha ee adag. Sapphire (Al₂O₃) waxay caan ku tahay adkaanteeda sare, tan labaadna dheemanka, iyadoo bixisa iska caabin xoqid oo aad u fiican iyo xasillooni muddo dheer ah. Waxay bixisaa gudbin sare oo indhaha ah oo ku baahsan baaxad ballaaran (UV ilaa IR, 200–5000nm), birefringence hooseeya, iyo xasillooni kuleyl oo heer sare ah, iyadoo ilaalinaysa waxqabadka indhaha xitaa heerkulka sare iyo soo-gaadhista kiimikada ee adag.

Codsiyada Indhaha

Qaybaha qaabaysan ee safayr sidan oo kale ah ayaa si weyn loogu isticmaalaa nidaamyada kala duwan ee indhaha oo ay ku jiraan:

muraayadaha indhaha ee laysarka- sida daaqadaha saxda ah, shaandheeyayaasha, iyo walxaha isku xidhka ee ku jira dejimaha laysarka awoodda sare leh.
Nidaamyada sawirka iyo dareenka- aaladaha sawir-qaadista hawada sare, caafimaadka, iyo warshadaha halkaas oo caddeynta indhaha iyo iska caabbinta deegaanka ay muhiim yihiin.
Spectroscopy iyo photonics- sida substrate-yada loogu talagalay dahaarka indhaha, muraayadaha indhaha, iyo qaybaha qaabaynta alwaaxa.
Muraayadaha ilaalinta- kamaradaha, dareemayaasha, iyo aaladaha indhaha ee la kulma jawi xoqid ama cadaadis sare leh.

Su'aalaha Badiya La Weydiiyo ee Muraayadaha Quartz

S1: Maxay yihiin faa'iidooyinka ugu muhiimsan ee daaqadaha indhaha ee aan caadiga ahayn ee safayr marka loo eego quartz ama silica la shiiday?

A: Sapphire waxay bixisaa adkeysi sare (Mohs 9), iska caabbinta kulaylka muddada-gaaban ee 1900°C, iyo gudbinta ballaaran ee 200-5500 nm, oo ka fiican quartz (xadka 1050°C) deegaannada aadka u daran.

S2: Waa maxay warshadaha sida caadiga ah u isticmaala daaqadaha indhaha ee aan caadiga ahayn ee safayr?

A: Waxay muhiim u yihiin hawada sare (optics-ka dayax-gacmeedka), endoscope-yada caafimaadka, nidaamyada laysarka warshadaha, iyo ogaanshaha infrared-ka difaaca sababtoo ah cimri dhererkooda iyo caddeyntooda indhaha.

Nagu Saabsan

XKH waxay ku takhasustay horumarinta tiknoolajiyadda sare, wax soo saarka, iyo iibinta muraayadaha indhaha ee gaarka ah iyo agabka cusub ee kiristaalka. Badeecadahayagu waxay u adeegaan qalabka elektaroonigga ah ee indhaha, qalabka elektaroonigga ah ee macaamiisha, iyo militariga. Waxaan bixinaa qaybaha indhaha ee Sapphire, daboolka muraayadaha taleefanka gacanta, dhoobada, LT, Silicon Carbide SIC, Quartz, iyo wafers kiristaal semiconductor ah. Iyada oo leh khibrad xirfadeed iyo qalab casri ah, waxaan ku fiicanahay habaynta wax soo saarka aan caadiga ahayn, annagoo higsanayna inaan noqono shirkad hormuud u ah qalabka optoelectronic-ka ee tiknoolajiyada sare.
