Abstract
A method of producing fluoroapatite powder by using a calcium compound, a phosphate compound, and a fluorine compound as a raw material is provided. The method comprises: preparing a slurry containing fluoroapatite produced from the raw material by using a wet process; applying an ultrasonic wave to the slurry; and drying the slurry to obtain the fluoroapatite powder mainly constituted of the fluoroapatite. The method provides fluoroapatite powder having improved particle strength. Further, an adsorption apparatus including the fluoroapatite powder is also provided.
