Thermal conductivity of several geopolymer composites and discussion of their formulation

International Journal of Applied Ceramic Technology, Volume 20, Issue 1, Page 475-486, January/February 2023., 2023
Abstract We fabricated 50.8‐mm cube‐shaped samples of metakaolin geopolymer (GP) composites with various additives chosen to increase or decrease the thermal conductivity of the composite. Sodium‐based GP (NaGP) and GP composites were more conductive than potassium‐based GP (KGP) composites for a given phase fraction of filler, but the maximum amount ...
