Abstract: A flame photometric method to det. K2O and Na2O in silicates is described. The mutual effect of K and Na, a great disturbing effect of Ca, and almost negligible effect on Al at higher concns. of Al2O3 was detd. Fe2O3 and MgO up to 10-15% have no effect. The accuracy of this method is not as good as Lawrence-Smith's method but it is time saving and can be carried out with less-qualified persons.
