Title:
【発明の名称】多結晶窒化ケイ素から多孔質の成形体を作製する方法
Document Type and Number:
Japanese Patent JP2003535006
Kind Code:
A
Abstract:
The invention concerns a new and improved method for the production of porous and formed bodies with polycrystalline structure that meets the high quality requirements of the usually excellent material characteristics of porous and formed bodies based on silicon nitride and, at the same time, at least considerably reduces known disadvantages of other state-of-the-art techniques. In this, it is provided to first precompress the silicon nitride powder mix with a modal particle distribution of coarse and fine particles to form a green body, and to subsequently bake it using a temperature-based sintering process.
