Abstract
A wire-shaped grinding element (10) is used as a grinding element for a polishing brush. The wire-shaped grinding element (10) includes inorganic filaments and a resin that impregnates the inorganic filaments and is cured. The inorganic filaments contain 80 to 90% by weight of an alumina component and 20 to 10% by weight of a silica component. The crystal structure of the inorganic filaments includes mullite crystals and intermediate lumina. The mullite crystals have an average grain size smaller than 25 nm.
