Preparation of reformed MgO filler with high humidity resistance by a hydrothermal coating technique.

open access: yesJournal of Asian Ceramic Societies, 2021
MgO is an excellent candidate for thermal conductive fillers due to its high thermal conductivity, low electric conductivity, low cost, and appropriate hardness, though the reaction with water to form Mg(OH)2 causes a decrease in the weatherability of ...
