Claim Text:
1. A method for forming an alkali metal ion source with a moderate rate of the ion release, comprising the steps of: a) combining a first component particulate alkali metal ion-bearing framework silicate with a second component that includes at least one of an oxide and a hydroxide of at least one of an alkaline earth metal and an alkali metal to form a solid mixture, wherein the molar ratio of the silicon to the at least one of the alkaline earth metal and alkali metal of the second component in the solid mixture is in a range of between about 1.0:0.1 and about 1.0:0.3; and b) exposing the solid mixture to a hydrothermal treatment to form a gel that includes the silicon and the alkali metal of the first component, thereby forming the source of alkali metal ion.
