The miscibility gap was observed in the concentration range from 1 to 250 micro-M. The coexistence of gas-liquid-solid (crystalline solid) was microscopically recognized from the peripheral to the center of the condensates. There was an upper limit of salt concentration where the phase separation disappeared, showing near critical behavior of macroscopic density fluctuation from 250 micro-M to 1 mM. These results add new experimental evidence to the existence of colloidal gas-liquid condensation and specify conditions of like-charge attraction between particles., 共催: 日本学術会議, joint hosting: The Science Council of Japan, 資料番号: AA0064730009}, publisher = {宇宙航空研究開発機構宇宙科学研究本部, Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)}, title = {重力沈降過程におけるコロイド粒子の異常な自己集積現象(その2)}, volume = {26}, year = {2010} }
