Title:
METHOD FOR PRODUCING ALKALINE EARTH THIOALUMINATE-BASED FLUOROPHOR
Document Type and Number:
Japanese Patent JP2005344094
Kind Code:
A
Abstract:
To provide a new method for producing such an alkaline earth thioaluminate-based fluorescent compound that only the diffraction pattern of a perfect alkaline earth thioaluminate compound is detected and no other substances' diffraction patterns are recognized in the X-ray diffractometry.
The method for producing the alkaline earth thioaluminate compound involves using metallic aluminum powder ≤150μm in particle size instead of aluminum sulfate, although, in general, aluminum sulfate is used as raw material for aluminum.
