WebOct 24, 2024 · The precise temperature for annealing can vary based on the precise composition of the glass from as low as 750 degrees Fahrenheit to as high as 1000 degrees Fahrenheit. The rate at which the glass must cool may also change - generally, larger pieces of glass must cool more slowly than smaller pieces. WebThis study reveals the effect of low-temperature air annealing on various physical properties of Zn (1-x) Sn (x) O (x = 0.14) (TZO) thin films. The thin films were grown on glass substrates by co-sputtering techniques and the grown films were subjected to low temperature air -annealing. dxfとは 図面 https://pazzaglinivivai.com
