| 摘 要： | 电气石具有自发电极属性,对改变水团的缔合度具有一定作用。笔者研究了朝鲜多个地区电气石的成分、结构和理化性能,并以其为主要原料制备了不同类型的电气石陶瓷,同时研发了一种间接测量水团缔合度的方法,该方法是利用水溶液的电容和介电损耗值来间接评价水团缔合度,可以反映水团缔合度的相对大小。研究表明,以高钙电气石为原料、适当添加活性剂并经700℃烧结工艺制备的电气石陶瓷,对降低水团缔合度具有明显效果。

| Abstract: | Tourmaline exhibits spontaneous electrode property that plays a role in changing the associated degree of water cluster. The composition, structure and physicochemical properties of tourmaline in various regions of North Korea are studied, using tourmaline as the main raw material to produce different types of tourmaline ceramics, and a method for indirectly measuring the associated degree of water cluster is developed.The method indirectly evaluates the water cluster using water capacity and dielectric loss value, and it can reflect the relative associated degree of water cluster. The results show that tourmaline ceramics using high-calcium tourmaline as raw materials, with proper addition of active agents and sintered at 700℃ can significantly reduce associated degree of water cluster. |
