PHYSICAL AND CHEMICAL PROPERTIES OF A NICKEL CATALYST PROCESSED UNDER MICROGRAVITY.

A description is given of processing a nickel catalyst under microgravity. It is set up to compare the payload catalyst and a reference sample produced on earth. The examination methods are hydrogenperoxide decomposition, stereoselective hydrogenation with hydrazine and some physical methods. It was found an abnormal thermal behavior of the microgravity processed catalyst. Also the kinetic data are differing from normal. From electron microscopy and x-ray analysis a clue was found on a different structure of the payload catalyst.
