摘要:

为实现攀西矿产资源在陶瓷釉料领域的应用,本研究以攀西地区高岭土和钒钛磁铁矿为原料,通过正交与单因素试验优化,成功制备出红色油滴釉。最佳工艺参数为1 250 ℃烧结、保温20 min,所得釉面油滴斑纹圆润,光泽度达70.5 GU。XRD与拉曼分析表明,釉层主晶相为α-Fe2O3,源于钒钛磁铁矿高温氧化;油滴生长符合JMA动力学模型,保温20 min时速率常数最高(K=2.535),30 min时油滴覆盖率峰值达77.77%。烧成制度调控机制显示:温度(1 240~1 260 ℃)升高促进油滴生长,但超过1 260 ℃会因熔体黏度降低导致异常团聚;保温时间(10~30 min)延长可提升析晶均匀性,但超过30 min会引发奥斯特瓦尔德熟化。

Abstract:

To implement the use of mineral resources from Panxi in ceramic glaze materials, this study successfully produced a red oil droplet glaze using kaolinite and vanadium-titanium magnetite from the Panxi region as raw materials through orthogonal and single-factor experimental optimization. The optimal process parameters are sintering at 1 250 ℃ with a holding time of 20 min. The resulting glaze surface exhibits round oil droplet patterns with a glossiness of 70.5 GU. XRD and Raman analysis confirm that the main crystalline phase in the glaze layer is α-Fe2O3, formed as a result of high-temperature oxidation of vanadium-titanium magnetite. The growth of oil droplets corresponds to the JMA kinetic model, with the highest rate constant (K=2.535) observed at a holding time of 20 min. After 30 min, the oil droplet coverage peak reaches 77.77%. The mechanism of firing mode control shows that an increase in temperature (1 240~1 260 ℃) promotes the growth of oil droplets, but exceeding 1 260 ℃ causes abnormal agglomeration due to a decrease in melt viscosity. Increasing the holding time (10~30 min) improves the uniformity of crystallization, but exceeding 30 min causes Ostwald ripening.
