초록

粘土鑛物과 滑石과의 關係에 對한 正確한 報告가 거의 없어. 이에 對한 磁器化溫度範圍 및 電氣的絶緣性과 粘土含量의 關係를 究明하였다. 스테아타이트素地의 製造에 使用한 原料는 國産 滑石, 粘土, 長石, 硅石等이며, 吸水率, 燒成線收縮率을 測定 檢討하고, 또 磁器化된 素地들의 電氣的絶緣性을 測定하였다. 그 結果 磁器化溫度範圍는 재겔錐 1乃至 3番內에 있었으며 $MgCO_3$를 添加함에 따라 燒成收縮은 크게 일어났으나, 粘土含量이 20% 以下였을 때는 磁器化溫度範圍가 增大되었다. 耐熱性은 全般的으로 良好하였으며 粘土量을 增加시킴에 따라 膨脹率, 誘電體力率, 絶線耐性은 增加하고, 體積固有抵抗은 減少하였다.

A review of the literature is cited. Little exact information exists on the relation between clay materials and talc. The raw materials which are used in making steatite body consist of talc, clay, feldspar, and flint mined in Korea. The percentage absorption and linear burning shrinkage are measured and then discussed. The vitrified bodies were used in measurement of dielectric properties. The method of measurements for dielectric properties are described too.
