Sapphire Tube sapphire rods speacial zoo siab-siab KY thiab EFG
Kev piav qhia
Sapphire Rods yog siv rau ntau yam kev siv. Lub pas nrig sapphire tuaj yeem ua nrog txhua qhov chaw polished rau kev siv kho qhov muag thiab hnav lossis nrog txhua qhov chaw zoo zom (tsis yog polished) los ua ib qho insulator.
Technology
Thaum lub sij hawm tus txheej txheem ntawm rub sapphire hlab los ntawm ib tug yaj nrog kev pab los ntawm ib tug noob, longitudinal kub gradient nyob rau hauv cheeb tsam ntawm lub solidified pem hauv ntej thiab cheeb tsam ntawm rub qhov twg qhov kub ntawm 1850 thiab 1900 deg. C yog tswj tsis pub tshaj 30 deg. C/cm. Lub raj thiaj li loj hlob yog annealed ntawm qhov kub ntawm 1950 thiab 2000 deg. C los ntawm kev nce qhov kub ntawm tus nqi ntawm 30 mus rau 40 deg. C / min thiab khaws lub raj ntawm qhov ntsuas kub thaum lub sijhawm ntawm 3 thiab 4 teev. Tom qab ntawd lub raj yog txias mus rau chav tsev kub ntawm tus nqi ntawm 30-40 deg. C/min.
Semiconductor Processing Applications:
(HPD CVD, PECVD, Etch, ntub dej)
Plasma applicator tube
Cov txheej txheem roj injector nozzles
Endpoint ntes
Excimer Corona Tubes
Plasma cov hlab ntsha
Plasma tube sealing tshuab yog ib yam khoom siv los encapsulate cov khoom siv hluav taws xob. Nws lub hauv paus ntsiab lus yog siv qhov kub thiab txias siab ntawm cov ntshav plasma kom yaj cov khoom ntim thiab ntim nws ntawm cov khoom. Cov khoom tseem ceeb ntawm plasma tube sealing tshuab suav nrog lub tshuab hluav taws xob plasma, raj sealing chamber, lub tshuab nqus tsev, tswj qhov system, thiab lwm yam.
Thermocouple tiv thaiv sheath (Thermowell): Thermocouple yog ib qho kev ntsuas kub uas feem ntau siv rau hauv qhov ntsuas kub ntsuas, nws ncaj qha ntsuas qhov kub thiab txias, thiab hloov cov teeb liab kub mus rau lub teeb liab hluav taws xob hluav taws xob hluav taws xob, los ntawm cov cuab yeej hluav taws xob (secondary instrument) mus rau qhov kub thiab txias. ntsuas nruab nrab
