Kev Piav Qhia Luv:

"Fused Silica" lossis "Fused Quartz" uas yog theem amorphous ntawm quartz (SiO2). Thaum piv rau borosilicate iav, fused silica tsis muaj cov khoom ntxiv; yog li nws muaj nyob rau hauv nws daim ntawv ntshiab, SiO2. Fused silica muaj kev sib kis ntau dua hauv infrared thiab ultraviolet spectrum thaum piv rau iav ib txwm. Fused silica yog tsim los ntawm kev yaj thiab rov khov dua ultrapure SiO2. Synthetic fused silica ntawm qhov tod tes yog ua los ntawm silicon-nplua nuj tshuaj precursors xws li SiCl4 uas tau gasified thiab tom qab ntawd oxidized hauv H2 + O2 huab cua. Cov hmoov SiO2 tsim nyob rau hauv cov ntaub ntawv no yog fused rau silica ntawm ib lub substrate. Cov fused silica blocks raug txiav rau hauv wafers tom qab ntawd cov wafers thaum kawg polished.
