Abstract

|
|
The purpose of this research was to investigate the general properties and main ingridients of Hwangtoh, which is the Korean loess. It is well known as a raw material of pottery shown to be widely scattered on the earth, especially in Korea. It belongs to primary clay that was found to be rich on mountain surface or field. In this study, XRF Spectral method was employed to analyze the chief ingredients of Hwangtoh, being found to consist of 43∼50. The ferric oxide contents of Hwangtoh from San Chung, Ha Dong, Ko Ryung, Ouk Chong, Bang Gae and Song Kwang were 6.46, 7.96, 11.26, 9.36, 9.06 and 9.28 %, respectively. The general characteristics of Hwangtoh from different places were studied by determining the content of water and the capacity to maintain temperature. Based on the above results, Hwangtoh could be said to have better quality than primary clay of Kaolin dose, and also would be able to find an application in construction formulations.
