GLASSES AND GLASS-CERAMICS AND METHODS OF MAKING THEM
A glass includes from 42 mol % to 47 mol % P.sub.2O.sub.5, from 42 mol % to 48 mol % CuO, and from greater than 0 mol % to 15 mol % Fe.sub.2O.sub.3. The glass is an amorphous, single-phase glass. Methods of making a glass article include heating batch materials to a melting temperature from 900° C. to 1350° C. In aspects, methods include pouring the molten glass in an inert gaseous environment, and cooling the molten glass in the inter gaseous environment. In aspects, methods include cooling the molten glass to form the glass article and annealing the glass article without growing crystals in or on the glass article during the cooling or the annealing.
PROCESS FOR THE TRANSFORMATION OF ANTIMICROBIAL GLAZED MATERIAL
The process for transforming an industrial soda-lime-type base glass plate into a glazed material with antimicrobial properties and personalized color consists in an antimicrobial glazed material production process. Copper nanoparticles (NPCu) are added to said glass with the aim of directly altering cell protection against viruses and bacteria in order to destroy their genetic material. The antibacterial glass is specifically applied to the industrial sector of surfaces and covers that are usually used in hospital facilities, and covers for the handling of food and beverages, among other uses.
GLASSES AND GLASS-CERAMICS AND METHODS OF MAKING THEM
Phosphate glasses and glass-ceramics exhibit a positive percent kill as measured by United States EPA Test Method for Efficacy of Copper Alloy Surfaces as a Sanitizer and/or have a CIELAB L* value below 35, CIELAB a* and b* values within 5 of zero.
