Abstract
A method of producing a ceramic sheet includes: shaping a composition containing a resin and a ceramic material into a sheet-like form through pressure application to perform primary sheet shaping; stacking a plurality of the primary sheet in a thickness direction or performing folding or winding of the primary sheet to obtain a laminate; slicing the laminate at an angle of 45° or less relative to a stacking direction to obtain a secondary sheet; and firing the secondary sheet.
Claims4
A method of producing a ceramic sheet comprising:
- shaping a composition containing a resin and a ceramic material into a sheet-like form through pressure application to obtain a primary sheet, wherein a volume fraction of the ceramic material in the primary sheet is not more than 65 volume % based on total volume of the resin and the ceramic material;
- stacking a plurality of the primary sheet in a thickness direction or performing folding or winding of the primary sheet to obtain a laminate;
- slicing the laminate at an angle of 45° or less relative to a stacking direction to obtain a secondary sheet;
- firing the secondary sheet so as to obtain the ceramic sheet having a value a/c of not less than 60.30, obtainable by dividing a-axis value by c-axis value upon Lotgering method, and
- the volume fraction of the ceramic material in the primary sheet is not less than 60 volume % based on the total volume of the resin and the ceramic material.
