Sapphire Tube sapphire rods tshwj xeeb zoo li siab siab KY thiab EFG
Kev piav qhia
Cov pas nrig sapphire siv tau ntau yam. Ib tug pas nrig sapphire tuaj yeem ua nrog txhua qhov chaw polished rau optical thiab hnav daim ntawv thov lossis nrog txhua qhov chaw sib tsoo zoo (tsis-polished) los ua haujlwm ua insulator.
Kev Siv Tshuab
Thaum lub sijhawm rub cov raj sapphire los ntawm cov yaj nrog kev pab los ntawm noob, qhov kub thiab txias ntev nyob rau hauv thaj chaw ntawm lub hauv ntej khov thiab thaj chaw rub qhov twg qhov kub yog ntawm 1850 thiab 1900 deg. C yog khaws cia tsis pub tshaj 30 deg. C/cm. Lub raj uas loj hlob yog annealed ntawm qhov kub ntawm 1950 thiab 2000 deg. C los ntawm kev nce qhov kub ntawm tus nqi ntawm 30 txog 40 deg. C/min thiab khaws lub raj ntawm qhov kub hais thaum lub sijhawm ntawm 3 thiab 4 teev. Tom qab ntawd lub raj raug txias mus rau chav tsev kub ntawm tus nqi ntawm 30-40 deg. C/min.
Cov ntawv thov ua semiconductor:
(HPD CVD, PECVD, Qhuav Etch, Ntub Etch)
Lub raj mis thov plasma
Cov roj injector nozzles
Lub tshuab ntes qhov kawg
Cov raj xa dej Excimer Corona
Cov raj xa dej plasma
Lub tshuab kaw lub raj plasma yog ib lub cuab yeej siv los kaw cov khoom siv hluav taws xob. Nws lub hauv paus ntsiab lus yog siv qhov kub thiab siab ntawm plasma los yaj cov khoom ntim thiab kaw nws rau ntawm cov khoom. Cov khoom tseem ceeb ntawm lub tshuab kaw lub raj plasma suav nrog lub tshuab tsim plasma, chav kaw lub raj, lub tshuab nqus tsev, lub kaw lus tswj, thiab lwm yam.
Lub plhaub tiv thaiv thermocouple (Thermowell): Thermocouple yog ib qho khoom siv ntsuas kub uas siv ntau hauv cov cuab yeej ntsuas kub, nws ncaj qha ntsuas qhov kub, thiab hloov cov teeb liab kub mus rau hauv lub teeb liab thermoelectric electromotive force, los ntawm cov cuab yeej hluav taws xob (cov cuab yeej thib ob) mus rau hauv qhov kub ntawm qhov ntsuas nruab nrab.
