Beschreibung
Zusammenfassung:	A metal-containing magnesium oxide powder is provided to ensure particle diameter and crystalline which are similar to a metal-free magnesium oxide powder and to improve discharge efficiency of a plasma display panel. A metal-containing magnesium oxide powder for a plasma display panel includes metal element 0.01~5 weight% and performs cathode luminescence in wavelength area 200~700 nm. The magnesium oxide powder has specific surface area of 0.1~40 m^2/g and particle size of 10 micron or less. A method for manufacturing the metal or halogen element-containing magnesium oxide powder comprises the steps of: adding 0.01~5 weight% of metal element, or metal element and halogen element; and performing heat treatment at 600~1400‹C in an oxidizing atmosphere.
