| 中文摘要: |
| 以陶瓷原料中常见的高岭土和围场土为研究对象,考察粒度、升温速率对两种矿物差热分析(DTA)曲线的影响。实验结果表明:不同矿物的粒度、升温速率对差热分析曲线有较明显的影响,即随着试样粒度的增大,差热分析曲线的峰形越来越低,越来越平坦,反应温度滞后；而随着升温速率的提高,差热分析曲线的峰形越来越高,越来越尖锐,反应温度也会发生滞后。 |
| 英文摘要: |
The author of this paper studied the effect of the particle size, heating rate of Kaolin and paddock soil(two common ceramic raw materials) on the differential thermal analysis (DTA) curves.
e results show that different mineral particle sizes, heating rates greatly influence the differential thermal analysis curves, i.e.
th the increase of particle sizes of the samples, the peak of the differential thermal analysis curve becomes lower and flatter, and the reaction temperature lags behind； and with the increase of heating rate, differential thermal analysis curve shape is higher and sharper, and the reaction temperature also falls behind. |
