Zusammenfassung:PROVIDED IS A SILICON NITRIDE POWDER FOR SILICONITRIDE PHOSPHOR HAVING HIGH LUMINANCE, A SR3AL3SI13O2N21 PHOSPHOR AND A β-SIALON PHOSPHOR USING THE POWDER, WHICH CAN BE USED FOR VACUUM FLUORESCENT DISPLAYS (VFDS), FIELD EMISSION DISPLAYS (FEDS), PLASMA DISPLAY PANELS (PDPS), CATHODE RAY TUBES (CRTS), LIGHT EMITTING DIODES (LEDS), OR THE LIKE, AND PROCESSES FOR PRODUCING THESE PHOSPHORS. THE SILICON NITRIDE POWDER FOR THE SILICONITRIDE PHOSPHORS IS A CRYSTALLINE SILICON NITRIDE POWDER FOR USE AS A RAW MATERIAL FOR PRODUCING SILICONITRIDE PHOSPHORS INCLUDING A SILICON ELEMENT, A NITROGEN ELEMENT, AND AN OXYGEN ELEMENT, AND HAS AN AVERAGE PARTICLE DIAMETER OF 1.0 TO 12 µM AND AN OXYGEN CONTENT OF 0.2 TO 0.9% BY WEIGHT.
