Abstract
An aspect of the present invention relates to a method of modifying a surface of a powder, comprising mixing a powder with a compound denoted by general formula (I): wherein, in general formula (I), each of R 10 and R 13 independently denotes a hydrogen atom, alkyl group, or aryl group, each of R 11 and R 12 independently denotes an alkyl group or an aryl group, and L denotes a single bond or an oxygen atom.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1 . A method of modifying a surface of a powder, comprising mixing a powder with a compound denoted by general formula (I):
wherein, in general formula (I), each of R 10 and R 13 independently denotes a hydrogen atom, alkyl group, or aryl group, each of R 11 and R 12 independently denotes an alkyl group or an aryl group, and L denotes a single bond or an oxygen atom, and wherein the powder is a nonmagnetic powder.
2 . The method of modifying a surface of a powder according to claim 1 , wherein the nonmagnetic powder is comprised in a nonmagnetic coating material.
3 . The method of modifying a surface of a powder according to claim 2 , wherein the surface of the nonmagnetic powder is modified to improve dispersibility of the nonmagnetic powder in the nonmagnetic coating material.Join the waitlist — get patent alerts
