Title:
調節された気孔率を有する炭化ケイ素
Document Type and Number:
Japanese Patent JP3682726
Kind Code:
B2
Abstract:
Silicon carbide sintered bodies having controlled porosity in the range of about 2 to 12 vol% in which the pores are generally spherical and about 50 to 500 microns in diameter, are prepared from raw batches containing a polymer fugitive. Sintered bodies in the form of mechanical seal members exhibit lower power consumption at low PV and, in addition, lower wear rates at high PV in comparison to commercially available silicon carbide seal members.
