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

The contact angle and surface free energy were characterized by the OCA-30 automatism contact angle test system. Through studied the influence of RECP on the surface free energy of ceramic glaze and movement modality of oil on the ceramic glaze in the water, the results show that the ceramic surface free energy increase obviously after dope RECP. Analysis and calculation show that the surface free energy increase mainly profited from the surface hydroxyl groups increase.展开更多
