Document Type and Number:
WIPO Patent Application WO/2021/079793
Kind Code:
A1
Abstract:
[Problem] To provide: a ceramic composite that can have a reduced size or thickness, and can efficiently dissipate heat; and a production method for the ceramic composite. [Solution] This ceramic composite is produced by: a step for preparing a melt comprising at least aluminum oxide and yttrium oxide; a step for bringing either sapphire crystal or ruby crystal into contact with the melt to melt a crystal portion thereof which is in contact with the melt, and to, as a result of the melting, integrate an Al2O3 phase of the crystal and an Al2O3 phase of the aluminum oxide together without a junction interface thereof; and a step for cooling the melt. The produced ceramic composite has at least two oxide phases, i.e., a Y3Al5O12 phase and an Al2O3 phase, as a lamellar structure, wherein an Al2O3 phase, and an Al2O3 phase of either the sapphire crystal or the ruby crystal, are integrated together without a junction interface thereof.
