Title:
DYNAMIC SINTERING METHOD FOR NITRIDE CERAMIC SUBSTRATE
Document Type and Number:
WIPO Patent Application WO/2023/184934
Kind Code:
A1
Abstract:
Provided in the present invention is a dynamic sintering method for a nitride ceramic substrate, which belongs to the technical field of ceramic materials. In the present invention, by means of the differences between a support block and a nitride ceramic substrate in the shrinkage starting temperature and the shrinkage rate, the shrinkage starting temperature of the support block is controlled to be lower than or higher than that of the nitride ceramic substrate, and the linear shrinkage rate thereof in a height direction is controlled to be higher than that of the nitride ceramic substrate, such that the dynamic process from non-contact to contact between a pressing plate and the substrate during the sintering process can be achieved; therefore, the deformation and cracking of the substrate during sintering are avoided.
