3 more elements
A method for preparing a microcapsule, the method comprising:
- providing at least one iron containing compound;
- providing at least one source of an inert gas;
- providing at least one inorganic shell precursor;
- combining the at least one iron containing compound, the at least one source of inert gas, and at least one inorganic shell precursor in an aqueous solution to form a suspension;
- stirring the suspension;
- maintaining a temperature and pH operable to precipitate the at least one inorganic shell precursor;
- and
- isolating the microcapsules from the suspension.
