Halloysite is one of the clay minerals in Bizen-clay. In this study we investigated the reaction between halloysite and potassium halide in the heating process. Halloysite reacted with potassium halide to form hydrogen halide and water in its dehydroxylation process. When excess potassium halide was added to halloysite, residual potassium halide melted and vanished at about 900℃ through vaporization. When 1 mole of potassium halides were added to 1 mole of halloysite, leucite was formed with exothermic peak observed hrough the thermal analysis. Kaliophilite was formed with exothermic peak when 2 moles of potassium halides were added to halloysite at the temperatures of 1040-1090℃.}, pages = {109--115}, title = {ハロイサイトとハロゲン化アルカリの加熱変化}, volume = {26}, year = {1991}, yomi = {ヤマグチ, カズヒロ and クサノ, ヨシヒロ and フクハラ, ミノル and ドイ, アキラ} }
