Chemical resistance of valve packing and sealing materials to molten nitrate salt
Description
Chemical compatibility between a number of compression packings and sealing materials and molten sodium nitrate-potassium nitrate was evaluated at temperatures of 2880C (5500F), 4000C (7500F), and 5650C (10500F). The types of packing materials tested included graphite, asbestos, PTFE, aramid, glass and ceramic fibers; perfluoroelastomers, and boron nitride. Several materials were chemically resistant to the molten salt at 2880C, but the compatibility of packings at 4000C and 5650C was not adequate. The chemical and physical phenomena affecting compatibility are discussed and recommendations concerning materials selection are made
