Japanese Patent JPS4988909
Kind Code:
A
Abstract:
This invention relates to the development of strong, highly porous glass-ceramic bodies exhibiting extremely high surface areas such as to render them eminently suitable for catalyst supports designed for use in emissions control systems utilized in combination with internal combustion engines. These bodies are manufactured through a leaching process which provides a surface layer or an entire bulk having a relatively homogeneous porosity with very high surface area wherein the size of the pores can be controlled to a reasonable uniformity.
