The purpose of this thesis is to develop a method which can be used to measure the thermal conductivity of oxide materials in the temperature range of 70 to 3000°F. Some of the many methods of measuring thermal conductivity, both transient and steady state, are reviewed. The heat pulse method which is a transient method appears to be the most promising, mainly because of its simplicity, short test time, and small sample size while still maintaining good accuracy. Some test equipment was assembled and actual test data taken for rutile (Ti02) at room temperature. The thermal conductivity of rutile as calculated from the data taken was, K = 4.03 BTU/hr ft °F. The estimated experimental uncertainty of this value is ± 81%. Future work in development of the heat pulse method should include improvements in the heat source, determining the thermal boundary conditions on the sample more accurately, using the method at elevated temperatures, and using the method for a wider range of materials .
