Title:
APPARATUS AND METHOD FOR PRODUCING PHOSPHOR PRECURSOR
Document Type and Number:
Japanese Patent JP3969204
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an apparatus and a method for producing a phosphor precursor whereby the particle diameter and crystal habit of phosphor precursor particles can be controlled, and the phosphor precursor which gives a small-diameter and high-luminance phosphor can be obtained.
SOLUTION: The apparatus is constructed so that at least a phosphor material solution fed from a first passage and a phosphor material solution fed from a second passage are continuously sent to a third passage after their continuous collision and mixing, and the mixture after the collision is sent at a Reynolds number of 3,000 or larger for 0.001 sec or longer and then continuously discharged from the third passage.
