Abstract
Shaped articles having improved mechanical properties, e.g., stronger catalysts and catalyst supports, are produced by shaping a mass of particulate material, e.g., ceramic powder, into the form of the desired final article, the particulate material including a microbially produced poly-saccharide compound, and then consolidating the shaped article by heat treating same, e.g., to sintering or calcination temperatures.
