PRODUCTION OF ZNS-BASED MOLDED AND SINTERED BODY

摘要

PURPOSE:To stably obtain a large-sized molded and sintered body free from cracks in a completely sulfurized state by molding starting material prepd. by mixing ZnO powder with an electroluminescent activator and firing the resulting molded body in two steps at different temps. CONSTITUTION:Starting material prepd. by mixing ZnO powder with an electroluminescent activator such as MnSO4.H2O is molded and fired in two steps at <=700 deg.C for 10-180min and at >=800 deg.C for 10-180min in a sulfurizing atmosphere of H2S, etc.
