The reproducibility of thermal conductivity measurements on
fused silica glass by various investigators using different
techniques suggests its suitability as a standard for such
measurements. Our laboratory measurements with the needle
probe technique on chip samples of silica glass saturated with
water gave a value of 3.287 ± 0.154 (S.D.) mcal/cm s °C (n = 21) at 25 °C, which is within about 1% of the previously
determined values and the value given by the manufacturer for
this material. The good agreement indicates that the
flat-plate steady-state and needle probe transient methods give
the same value for this material, and that the water-saturated
chip technique is an accurate method to measure thermal
conductivity of isotropic samples.
