US 12,120,958 B2 · Method of manufacturing a curved ceramic structure

Abstract

A method of manufacturing a ceramic structure, a method of manufacturing a ceramic structure with multiple layers of ceramic material, and a method of manufacturing a piezoelectric ceramic structure. The method of manufacturing a ceramic structure includes the steps of: placing a sheet of ceramic material on a supporting platform, wherein the supporting platform is arranged to elevate the sheet of ceramic material from a base of the supporting platform by supporting only a first portion of the sheet of ceramic material; sintering the sheet of ceramic material; and during the step of sintering of the sheet of ceramic material, facilitating forming a curvature on the sheet of ceramic material at a second portion of the sheet of ceramic material which is not supported by the supporting platform.

Dependent claims

A method of manufacturing a curved piezoelectric ceramic structure, comprising the steps of:

mixing lead zirconate titanate powder with a binder to provide a mixture;
pressing the mixture into a sheet;
providing a supporting platform with at least one support structure and a base, the at least one support structure elevated from the base;
placing at least one first portion of the sheet on the at least one support structure such that a second portion of the sheet is not supported by the at least one support structure;
heating the sheet and at least the supporting platform to expel the binder from the sheet;
sintering the sheet;
and
during the step of sintering of the sheet, allowing bending under self-weight of the sheet to form a curvature on the second portion.
