• 中文摘要： 本文報告BK1光學玻璃浸於氯化銀/氯化鋅熔融鹽內進行銀/鉀離子交換的結果,銀與鉀離子在BK1內之濃度分布數據可用擴散數學模式描述,此模式以銀離子、鉀離子之自擴散係數作為參數,由470、500、520、540.degree.C離子交換所得之自擴散係數,可求得鉀離子自擴散之活化能22.4千卡/莫耳,銀離子自擴散之活化能35.4千卡/莫耳。
• 英文摘要： Ag/sup +/-K/sup +/ ion exchange is carried out by immersing a BK1 glass cylinder in a AgCl/ZnCl/sub 2/ molten salt. The concentration profiles of silver and potassium in BK1 are measured and correlated using a mathematical model with self-diffusion coefficients as undetermined parameters. Self-diffusion coefficients of Ag/sup +/ and K/sup +/ are estimated from the ion concentration profiles after exchange for 6 days at 470, 500, 520, 540.degree.C. The activation energies of self-diffusion coefficients of K/sup +/ and Ag/sup +/ are found to be 22.4 and 35.4kcal/mol, respectively.
