Abstract: Phosphosilicate ceramics with varying compositions were synthesized through the sol-gel process and the thermal conductivity of the samples was measured using the transient plane source (TPS) method. Results showed that the thermal conductivity of phosphosilicate ceramic powder was low, but increased slightly with phosphorous concentration. The low thermal conductivity of the ceramics could be useful in thermal barrier applications.
