Electrical double layer on silver iodide. Influence of temperature and application to sol stability

摘要: Results on the double layer charge and capacitance AgI previously obtained have been improved extended to include temperature dependency between 5 85°C. At room temperature, alkali ions adsorb specifically negative AgI, which gives rise a marked ion specificity in is responsible for lyotropic sequence coagulation concentrations. With increasing decrease, with concurrent decrease specificity. 65°C above, predominantly diffuse non-specific. The concentrations then also lost. There some evidence phase transition around 50°C adsorbed water layer.
