Abstract
A convenient and versatile method for preparing complex metal oxides is disclosed. The method uses a low temperature, environmentally friendly gel-collection method to form a single phase nanomaterial. In one embodiment, the nanomaterial consists of BaAMnBTiCOD in a controlled stoichiometry.
Claims9
A method for producing a metal oxide ceramic nanomaterial, the method comprising steps of:
- mixing a first metal-organic salt comprising a first metal (M1) and a second metal-organic salt comprising a second metal (M2) in an anhydrous solvent to form a first intermediate, wherein M1 is selected from the group consisting of barium, manganese, iron, nickel, copper, bismuth, cobalt, samarium, and praseodymium, and M2 is titanium;
- adding deionized water to the anhydrous solvent to hydrolyze the first intermediate to produce a precursor solution;
- permitting the precursor solution to form a gel wherein, after gel formation, at least 90% of M1 and M2 is integrated into the gel;
- and
- forming a hollandiate nanomaterial from the gel.

- mixing a first metal-organic salt comprising a first metal (M1) and a second metal-organic salt comprising a second metal (M2) in an anhydrous solvent to form a first intermediate, wherein M1 and M2 are independently selected from the group consisting of barium, manganese, titanium, iron, nickel, copper, bismuth, cobalt, samarium, and praseodymium, wherein M1 and M2 are different;
- adding deionized water to the anhydrous solvent to hydrolyze the first intermediate to produce a precursor solution;
- permitting the precursor solution to form a gel wherein, after gel formation, at least 90% of M1 and M2 is integrated into the gel;
- and
- forming a nanomaterial from the gel;
- wherein the first metal-organic salt is a 1,3 dicarbonyl salt.
