Abstract
The requirements which show evaluation and selection indicator of the heat-resistant materials in the apparatus design in consideration of continuous society are the database construction containing three kinds of risk indices about continuous supply of the resources, environmental change, and toxicity, and we have investigated the database structure. This report investigated the toxicity risk index of heat-resistant materials based on IC50 about the toxicity risk stored in the database. The Web information about three kinds of risk index which added the toxicity risk index was unified, and the relation between these risks and the high temperature properties of heat-resistant materials investigated. The optimal material selection indicator in the apparatus design used in the high temperature environment based on results is shown.
