(54) METHOD FOR MANUFACTURING TITANIUM BALL


(57) The present invention provides a manufacturing method for a titanium ball that improves a deodorizing function, an antibacterial function, an antifouling function, and an air and water purifying function of titanium dioxides so as to allow coating a base material (21, 22) with titanium oxide (23) simply and accurately, which is also a manufacturing method for a titanium ball that sufficiently displays the above-described functions even in a dark place such as a toilet tank, and is characterized by including a step of making titanium oxide powder collide and/or frictionally contact for discoloration.
