Resumo: Abstract Antimicrobial materials have long been used as an effective means of reducing the risks posed to humans by fungi, bacteria and other microorganisms. These materials are essential in environments where cleanliness, comfort and hygiene are the predominant concerns. This work presents preliminary results for a bactericidal vitreous material that is produced by the incorporation of a silver ionic specimen through ionic exchange reactions. Powdered glass was submitted to ionic exchange in an ionic medium containing AgNO3 as silver ions source. Different AgNO3 concentrations in ionic medium and different particle sizes of the glass were used in the samples development. Microbiological analysis of the samples was made by disk diffusion method in the Escherichia coli and Staphylococcus aureus bacterium species. Samples were still submitted to SEM-EDS, atomic absorption and X-ray diffraction techniques. Results showed that the bactericidal effect was dependent on AgNO3 concentration in the ionic exchange medium, but was not dependent on the particle size of the glass.
