Title:
SINTERED BODY
Document Type and Number:
WIPO Patent Application WO/2023/243542
Kind Code:
A1
Abstract:
This sintered body contains Al2O3, SiO2 and MnO and includes a primary crystal phase constituted from Al2O3, a first glass phase, and a second glass phase having a composition different from that of the first glass phase. The first glass phase and the second glass phase each contain SiO2 and MnO. The content ratio of SiO2 relative to the total amount of SiO2 and MnO in the first glass phase is greater than the content ratio of SiO2 relative to the total amount of SiO2 and MnO in the second glass phase.
