A hydrothermal synthetic study on the relationship between the stability and the composition of sodium saponite solid solutions revealed that a special trioctahedral sodium smectite can persist stably up to temper-atures as high as 850 ~ under a water pressure of 1 kb. This smectite has a composition close to Na0.ss(Mg2.70A10.30) (Si3.15A10.85)O10(OH)2. nHgO as estimated from the chemical composition of gels that yield this smectite in essentially pure form at the highest emperatures, and from other phase evidence. The composition range of these trioctahedral sodium smectites and phase relationships around the smectite field in the system NazO-MgO-Al2Oa-SiOE-H20 are also briefly described in the temperature ange 600-800 ~ under a pressure o...
