Abstract
Among the several possible methods for measuring thermal conductivities of loose-fill materials (powders, granules, or fibers) at high temperatures, the radial-heat-flow-in-a-cylinder method has the advantage that it inherently reduces the need for thermal guarding or accessory thermal insulation to restrict unwanted heat flow which can cause serious errors in results. This feature is important because, especially at high temperatures, the thermal insulation that may be needed in other methods, such as one using longitudinal heat flow in a cylinder, may be as conductive as the specimen being measured.
