Phase separated glass substrate with magnetizable component and antimicrobial component, method of forming the substrate, methods of using the substrate, and articles incorporating the substrate

Abstract

A glass-ceramic substrate includes a continuous glass phase; a magnetizable component; and an antimicrobial component. The substrate can further include a discontinuous glass phase disposed in the continuous glass phase. The magnetizable component and the antimicrobial component can be disposed in the discontinuous glass phase. The substrate can include 45 percent to 60 percent SiO2; 3 percent to 6 percent P2O5; 3 percent to 10 percent B2O3; 4 percent to 8 percent K2O; 7 percent to 15 percent Fe2O3; and 15 percent to 25 percent CuO. A ratio of the mole percentage of CuO to Fe2O3 in the substrate can be 1.3 to 3.0. The magnetizable component can include one or more of delafossite and magnetite. The antimicrobial component can include one or more of cuprite and metallic copper. The substrate can exhibit a magnetic permeability of greater than or equal to 1.02μR at a frequency of 10,000,000 Hz.
