抄録

Refractoriness and mineral compositions of various kinds of Amakusa pottery stones (218 samples) were measured by thermal expansion and X-ray powder diffraction methods respectively. The nominal temperature (Tsk) equivalent to refractoriness was predicted by thermal expansion curves. The mineral compositions were determined on the basis of X-ray powder profile refinement method. The statistics of data for Tsk (°C) and mineral compositions, such as quartz (QU (wt%)), sericite (SE (wt%)), kaolin (KA (wt%)), albite (AB (wt%)), calcite (CA (wt%)), siderite (SI (wt%)), showed a high correlation between them with the correlation coefficient of 0.981, which was expressed by Tsk=1404+2.98QU+0.00SE+1.72KA-3.20AB-23.2CA-24.4SI.
