Title:
PRODUCTION APPARATUS OF FLUORESCENT SUBSTANCE AND VESSEL FOR PRODUCING FLUORESCENT SUBSTANCE
Document Type and Number:
Japanese Patent JP3424165
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide the subject apparatus having a furnace for heating the raw materials for a fluorescent substance, and a specified vessel for producing the fluorescent substance, capable of efficiently promoting the reduction and nitridation even at the contacting surface with a boat, capable of providing a GaN-based fluorescent substance having good uniformity, and good crystalline shape having clear angles.
SOLUTION: Raw materials 3 is loaded on a boat 4 obtained, for example, by mixing a carbonic material such as graphite, amorphous carbon and a carbon-coated alumina, and a BN powder, with a binder, a solvent and the like, inserting the obtained mixture into a mold to compact the mixture, drying the obtained compact, and baking the dried compact, and the raw materials 3 loaded on the boat 4 are inserted into the interior of a tube furnace 1. The raw materials 3 are heated by a heater 2 while flowing ammonia gas in the interior of the tube furnace 1 to provide the fluorescent substance.
