Comparison of measurement methods for thermal conductivity of impermeable graphite materials
Impermeable graphite materials are heterogeneous and anisotropic materials.Currently,there is little research on the measure-ment of thermal conductivity of impermeable graphite materials in China.The current relevant standards mostly focus on isotropic homo-geneous materials with low thermal conductivity or materials without carbon or conductivity.This article compares the measurement re-sults of the thermal conductivity of impermeable graphite materials using three methods:steady-state plate method,planar heat source method,and comparison method.It is proposed that the comparison method is the best one,which is easy to operate,has high repeat-ability,and has small relative deviation,and can be promoted and used in the industry.
