To understand the effect of the powder characteristics of screen-printed protective layers on activation, we studied several types of MgO powder using parameters, fabrication methods such as vapor phase oxidation (VPO) and decomposition of Mg (OH) 2 (DOM), the BET value (particle surface area), and the particle size of the MgO powder. First, powders were analyzed by using FTIR, DSC, and TEM. Results show that VPO powder has a lower activation energy compared to DOM powder because of its high crystallinity, smooth surface, and non aggregated particles. Panels were then fabricated using these powders, and activated. To evaluate activation, we measured the firing voltage as a function of activation temperature and aging time. Panels using VPO powder were activated most easily at temperatures above 300°C and firing voltage stabilized within 20 minutes.
