Abstract:
1. A method of making a substantially phase pure compound of Formula I, wherein the method comprising: mixing a stoichiometric amount of anion X and a first amount of cation A in a ball-milling device, wherein the first amount of cation A is less than a stoichiometric amount of cation A, thereby consuming substantially all of the first amount of cation A and a first portion of anion X that is less than the stoichiometric amount of anion X to form a mixture of AX and unreacted X; and mixing a second amount of cation A with the unreacted X and the AX in the ball-milling device, wherein the second amount of cation A is less than the stoichiometric amount of cation A, thereby consuming substantially all of the second amount of cation A and a first amount of unreacted X, to afford substantially phase pure AX.
