Vim li cas quartz nkoj irreplaceable nyob rau hauv cov kev lag luam?
Tshuaj Inertness: Tiv thaiv cov tshuaj tiv thaiv acids, alkalis, chlorine, thiab cov txheej txheem gases ntawm qhov kub thiab txias.
Thermal stability: Zoo tshaj rau cov hlau los yog ceramics hauv thermal cycling ceev vim yog ultra-low CTE.
Optical Transparency: Tso cai rau UV-IR lub teeb xa mus rau kev yees duab-pab CVD txheej txheem.
Kev sib piv:
Silicon Carbide (SiC) nkoj: Tus nqi siab dua thiab rov ua haujlwm nrog oxygen (tsim CO2).
Nkoj Graphite: Kev pheej hmoo ntawm cov pa roj carbon monoxide cuam tshuam rau wafer resistivity.
Yuav ua li cas quartz nkoj ua haujlwm hauv photovoltaic ntau lawm kab?
Phosphorus Diffusion:
