Experiment results show that white glaze has a batch (aix strip) of overfine structure spectrum of Mn 2+ which pile up at the Fe 3+ spectrum at g =2. There is a Fe 3+ spectrum at g =4.3 as the baked temperature is higher while the Fe 3+ wide spectrum at g =2 intensities and Mn 2+ spectrum disappears. When temperature reaches 1300℃, the wide spectrum of Fe 3+ disappears but Fe 3+ spectrum at g = 4.3 intensities. Brown glaze at raw has no Mn 2+ spectrum,just has a wide spectrum at g =2. When the baked temperature is higher, the wide spectrum become narrower and intensities.展开更多
文摘This article introduces the change trend of impurity ions Fe 3+ and Mn 2+ in minerals which compose of glaze at raw and baked at different temperatures. Experiment results show that white glaze has a batch (aix strip) of overfine structure spectrum of Mn 2+ which pile up at the Fe 3+ spectrum at g =2. There is a Fe 3+ spectrum at g =4.3 as the baked temperature is higher while the Fe 3+ wide spectrum at g =2 intensities and Mn 2+ spectrum disappears. When temperature reaches 1300℃, the wide spectrum of Fe 3+ disappears but Fe 3+ spectrum at g = 4.3 intensities. Brown glaze at raw has no Mn 2+ spectrum,just has a wide spectrum at g =2. When the baked temperature is higher, the wide spectrum become narrower and intensities.
