Title:
PRODUCTION OF SILICON CARBIDE-BASED HONEYCOMB FILTER
Document Type and Number:
Japanese Patent JPH09202671
Kind Code:
A
Abstract:
To provide a method for producing a silicon carbide-based honeycomb filter, good in economical efficiency, having a low air permeation resistance and hardly leaking particulates.
A raw material mixture prepared by blending and mixing 100 pts.wt. α type silicon carbide powder having 0.3-50μm average particle diameter with 5-65 pts.wt. β type silicon carbide powder having 0.1-1.0μm average particle diameter, a binder for forming and a dispersion medium liquid is formed into a honeycomb filter shape having 0.05-1.0mm cell wall thickness according to an extrusion molding method. The resultant formed compact is then baked in a nonoxidizing atmosphere to recrystallize the β type silicon carbide powder.
