The glass formability of Ni75B17Si8 melt and the thermostability of this metallic glass formedfrom the the melt can be enhanced by eliminating the heterogeneous catalystg. The purificationwas done by cyclical superheating melt in special glasses and subsequently cyclicallysuperheating it in an electromagnetic levitation apparatus. The purified Ni75B17Si8 amorphoussample sized up to 20 I0 x 0.5 mm was prepared as four times the thickness of unpurifiedones.
