Abstract
Official abstract text for this publication.
A composite powder of the present invention includes a glass powder and a ceramic powder, wherein a content of the glass powder is from 30 vol % to 60 vol %, wherein a content of the ceramic powder is from 40 vol % to 70 vol %, wherein the glass powder includes as a glass composition, in terms of mass %, 10% to 30% of SiO2, more than 20% to 40% of B2O3, 20% to 40% of SrO+BaO, 0% to 10% of Al2O3, and 0% to 15% of ZnO, and wherein the composite powder is used for a light reflective substrate.
First claim
Opening claim text (preview).
The invention claimed is: 1. A composite powder, comprising a glass powder and a ceramic powder, wherein a content of the glass powder is from 30 vol % to 60 vol %, wherein a content of the ceramic powder is from 40 vol % to 70 vol %, wherein the glass powder comprises as a glass composition, in terms of mass %, 10% to 30% of SiO 2 , more than 20% to 40% of B 2 O 3 , 20% to 40% of SrO+BaO, 1% to 7% of Al 2 O 3 , and 1% to 15% of ZnO, wherein the composite powder is used for a light reflective substrate, and wherein the glass powder comprises as the glass composition, in terms of mass %, 10% or less of component(s) other than SiO 2 , B 2 O 3 , SrO, BaO, Al 2 O 3 , and ZnO. 2. The composite powder according to claim 1 , wherein the composite powder comprises alumina and zirconia as the ceramic powder. 3. A green sheet, comprising a composite powder, wherein the composite powder comprises the composite powder of claim 2 . 4. A light reflective substrate, comprising a sintered body of a composite powder, wherein the composite powder comprises the composite powder of claim 2 . 5. A green sheet, comprising a composite powder, wherein the composite powder comprises the composite powder of claim 1 . 6. A light reflective substrate, comprising a sintered body of a composite powder, wherein the composite powder comprises the composite powder of claim 1 . 7. A light emitting device, comprising the light reflective substrate of claim 6 . 8. The composite powder according to claim 1 , wherein the glass powder comprises as the glass composition, in terms of mass %, 26% to 40% of B 2 O 3 .
