Claims12
A method of making a chromium composition, comprising:
- reacting a chromium compound having chromium in the formal oxidation state of +4 with an oxygen atom source.
A method of making a thin film composition comprising:
- treating a heated substrate with (A) one or more volatile chromium compounds in the formal oxidation state of +4 and (B) a gas or vapor chosen from water, oxygen, ozone, hydrogen peroxide, silanol, or aryl hydrate.
A method of making a composition having the chemical formula MCrO3, comprising:
- reacting a chromium composition with an oxygen atom source and a salt of a divalent metal;
- wherein M is a divalent metal cation.
A method of making a composition comprising:
- reacting a compound having manganese in the formal oxidation state of +4 with water, oxygen, ozone, hydrogen peroxide, or aryl hydrate.
