Alumina catalyst carriers and the process for producing them

Abstract: Thermally stable, shaped alumina catalyst carriers are made by treating an alumina shape of predominantly chi-rho-eta or pseudoboehmite crystalline phase structure, or mixtures thereof, with an ammonium salt in an aqueous medium under pressure within the temperature range of about 100 DEG C and 250 DEG C, followed by removal of water-leachable constituents and a subsequent thermal activation step The products exhibit high thermal stability at elevated temperatures

Corrosion resistant vacuum brazing sheet

Abstract: A novel process for producing aluminum composite sheet products for roll forming and vacuum brazing is disclosed, which provides an unexpected improvement in the corrosion resistance of the brazed product. According to the process, a composite sheet is annealed to a strain-free state after having been rolled to a thickness which is a critical amount greater than the thickness ultimately sought. Following the annealing step, the sheet is cold worked to the desired thickness, the degree of reduction in this final step being within a critical range which provides the improvement in corrosion resistance to the final product after vacuum brazing.

Free silica analysis of environmental samples-a critical literature review.

Abstract: The various anlytical procedures for the analysis of free silica in environmental samples alt suffer serious deficiencies, to the extent that there is no acceptable routine method. Each sample represents a minor research effort. Many of the analytical uncertainties are related to an amorphous surface layer on quartz.
