AI Technical Summary
Technical Problem
Metal powders exhibit varying shapes, leading to inconsistent product quality due to differences in physical properties.
Method used
A method for producing tin flake powder involves preparing a tin foil less than 10 μm thick, subjecting it to embrittlement treatment, and irradiating it with ultrasonic waves using specific liquid mediums and conditions to control the shape variation.
Benefits of technology
The method produces tin flake powder with controlled length variations perpendicular to the thickness, enhancing product consistency and suitability for applications like pigments, metal pastes, and conductive materials.

Abstract
To provide a method for producing tin flake powder capable of suppressing variation in length extending in a direction orthogonal to thickness, and to provide the tin flake powder.SOLUTION: The method for producing the tin flake powder includes a preparation step of preparing a tin foil made of tin or a tin alloy, and an ultrasonic irradiation step of irradiating the tin foil 1 with ultrasonic waves using a liquid as a medium to break the tin foil 1. The thickness of the tin foil 1 is less than 10 μm.SELECTED DRAWING: Figure 1
