Production process of sheet-like dense cordierite sintered body

Abstract

There is provided a production process of a sheet-like dense cordierite sintered body which hardly generates cracks when dried and sintered, and has excellent formability. A production process of a sheet-like dense cordierite sintered body which has a step of forming a raw material containing cordierite powders having an average particle size of greater than 2 μm but not greater than 4 μm into a cordierite green sheet; and sintering the cordierite green sheet at from 1350 to 1450° C.

Description

Claims

1. A production process of a sheet-like dense cordierite sintered body, which comprises the steps of: forming a raw material containing cordierite powders having an average particle size of greater than 2 μm but not greater than 4 μm into a sheet form to form a cordierite green sheet; andsintering the cordierite green sheet at from 1350 to 1450° C.

2. A production process of a sheet-like dense cordierite sintered body according to claim 1, wherein the sheet-like dense cordierite sintered body has a porosity of 2% or less.

3. A production process of a sheet-like dense cordierite sintered body according to claim 1, wherein the cordierite powders have an average particle size of greater than 2 μm but not greater than 3 μm.

4. A production process of a sheet-like dense cordierite sintered body according to claim 1, wherein the sheet-like dense cordierite sintered body has a thickness of from 100 μm to 1.0 mm.
