PLASTIC BODY FOR ALUMINA STRUCTURE AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a plastic body for alumina structure which has excellent hardness characteristic and extrusion characteristic (high plasticity) to give a desired shape to an alumina formed body when being used for manufacturing the alumina formed body or an alumina structure after fired and in which a cost is lowered by simplifying a forming process, environmental load is reduced and the obtained plastic body for the alumina structure is made high in quality and an efficiently manufacturing method of the same.

SOLUTION: The plastic body for the alumina structure is manufactured by kneading alumina raw material powder containing at least 1 mass% hydraulic alumina powder forming a hydrate by hydration reaction and water and has characteristics of (1) 5-34 mm hardness characteristic and (2) ≥5 cm extrusion characteristic.
