摘要： THIS INVENTION RELATES TO THE STRENGTHENING OF GLASSCERAMIC ARTICLES IN WHICH THE CRYSTAL CONTENT THEREOF COMPRISES THE PREDOMINANT PART OF THE ARTICLES AND CONTAINING BETA-QUARTZ STUFFED WITH MAGNESIUM IONS AS THE PRIMARY CRYSTAL PHASE. THE STRENGTHENING IS SECURED THROUGH CONSECUTIVE ION EXCHANGE REACTIONS WHEREIN LITHIUM IONS FROM AN EXTERNAL SOURCE ARE FIRST EXCHANGED FOR MAGNESIUM IONS IN THE BETA-QUATRZ WITHIN A SURFACE LAYER ON THE ARTICLE AND THEREAFTER SODIUM AND/OR POTASSIUM IONS FROM AN EXTERNAL SOURCE ARE EXCHANGED FOR THE LITHIUM IONS DIFFUSED INTO THE STRUCTURE OF THE BETA-QUARTZ DURING THE FIRST EXCHANGE. THIS CONSECUTIVE ION EXCHANGE DOES NOT ALTER THE ESSENTIAL STRUCTURAL NATURE OF THE BETA-QUARTZ CRYSTALS BUT DOES CAUSE COMPRESSIVE STRESSES TO BE DEVELOPED IN THE SURFACE LAYER.

摘要： Processes for the preparation of base metal titanate catalysts in situ on refractory ceramic support structures which provide devices of significantly improved catalytic efficiency particularly suited for automotive exhaust emissions control applications are described. The base metal titanate catalysts comprise titaniferous crystal phases of spinel, ilmenite and/or pseudobrookite structure which consist essentially, in weight percent on the oxide basis, of about 15-85% TiO2, 15-70% M''''o, wherein M'''' is Mn 2, Co 2, Fe 2 or Cu 2, and 0-60% M2''''''O3, wherein M'''''' is A1 3, Fe 3, Cr 3, Mn 3 or Co 3. The process comprises preparing a solution of compounds of the desired metals, coating a refractory ceramic support structure with the solution, precipitating the desired metals from the solution onto the support structure as a coating of hydroxides, and firing the structure to convert the hydroxide coating to an oxide coating of the desired composition and crystalline structure.

摘要： 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.
