Abstract
Official abstract text for this publication.
Provided is a windowpane for a combustion apparatus in which a light-blocking layer containing an inorganic pigment powder and a glass powder is formed on a surface of a transparent crystallized glass plate and the light-blocking layer can sufficiently hide an adhesive, a gasket or the like used to fix the windowpane to the body of the combustion apparatus and which can reduce the occurrence of cracks due to heat in the light-blocking layer. A windowpane for a combustion apparatus in which a light-blocking layer containing an inorganic pigment powder and a glass powder is formed on a surface of a transparent crystallized glass plate, wherein the light-blocking layer contains 30 to 50% by mass of the inorganic pigment powder and 50 to 70% by mass of the glass powder and has a thickness of 1 to 10 μm and the inorganic pigment powder has an average particle size of 0.8 μm or less.
First claim
Opening claim text (preview).
The invention claimed is: 1. A windowpane for a combustion apparatus in which a light-blocking layer containing an inorganic pigment powder and a glass powder is formed on a surface of a transparent crystallized glass plate, wherein the light-blocking layer contains 30 to 50% by mass of the inorganic pigment powder and 50 to 70% by mass of the glass powder and has a thickness of 1 to 10 μm and the inorganic pigment powder has an average particle size of 0.8 μm or less. 2. The windowpane for a combustion apparatus according to claim 1 , wherein the light-blocking layer is formed on at least part of a peripheral portion of the transparent crystallized glass plate. 3. The windowpane for a combustion apparatus according to claim 1 , wherein the inorganic pigment powder is a powder of Cr—Fe—Co—Ni-based pigment. 4. The windowpane for a combustion apparatus according to claim 1 , wherein the transparent crystallized glass plate has an average coefficient of linear thermal expansion of −10×10 −7 to +30×10 −7 /° C. at 30 to 750° C. 5. A combustion apparatus including the windowpane for a combustion apparatus according to claim 1 .
