Title:
TUBE-SHAPED CALCIUM PHOSPHATE AND PROCESS FOR PRODUCTION THEREOF
Document Type and Number:
WIPO Patent Application WO/2010/140634
Kind Code:
A1
Abstract:
Disclosed are tube-shaped hollow particles which are characterized by having an average longer diameter (length) of 200 to 1000 nm inclusive, an average outer diameter of shorter diameters of 30 to 100 nm inclusive, and an average inner diameter of the shorter diameters of 29 to 99 nm inclusive. Also disclosed is a process for producing the tube-shaped hollow particles, which is characterized by comprising reacting an aqueous solution or suspension containing phosphoric acid with an aqueous solution or suspension containing a calcium compound. The tube-shaped hollow particles have nano-sized cross-section diameters, and are therefore expected to be used as a functional material such as a biomaterial, a filler for chromatography or a fluorescent material.
