MgO EVAPORATION SOURCE FOR PROTECTING PDP PROTECTING FILM AND A MANUFACTURING METHOD OF MgO SINTERED USING THE SAME

摘要

PURPOSE: An MgO evaporation source for protecting PDP protecting film and a manufacturing method of MgO sintered using the same are provided to improve the durability and property of PDP by using poly-crystal magnesium oxide as a vapor-deposition material for a PDP protective film.;CONSTITUTION: Material more than two kinds of scandium, gadolinium, zirconium and iron is selected and mixed with magnesium oxide. The mixture is calcinated with pellet shaped after molded. The calcined material is sintered in 1600-1700°C. The relative density of the sintering material is 95.5% or greater. The complex dopant is mixed at 1-200 ppm. Calcination is performed in 500-1000°C. Sintering is operated for 1-10 hours.;COPYRIGHT KIPO 2011
