PHYSICAL PROPERTIES OF HIGH TEMPERATURE MATERIALS Part Ⅳ.Thermal Diffusivity Apparatus for 100 to 1,500℃

摘要

An apparatus has been designed and constructed for measuring diffusivities up to about 1500℃. Values of thermal conductivity may be derived, from thermal diffusivity values using density and heat capacity values. The apparatus was designed for measurements on materials having thermal diffusivity values less than 0.1cm2/sec., such as most refractory oxides at moderate to high temperatures.
