The Institute of Ceramic Technology (ITC-AICE) and the Universitat Jaume I of Castelló (UJI), through the Predepartmental Unit of Medicine of the Faculty of Health Sciences and the Department of Agricultural Sciences and Natural Environment of the School of Technology and Experimental Sciences, are working for the second consecutive year on the Bioceram project, which is funded by the Regional Ministry of Innovation, Universities, Science and Digital Society through a Nominative Line of the GVA and whose objective is the development of ceramic surfaces with biocidal power. Thus, Bioceram focuses on being able to offer ceramic companies the necessary knowledge to obtain ceramic products for everyday use with biocidal properties, with which to respond to pandemics such as COVID-19 or future biological threats.

In 2021, the research work focused on the study and analysis of silver as a material that could meet the necessary conditions to activate the biocidal capacity and action on ceramic surfaces of tiles, roof tiles and porcelain tableware and sanitary ware. "This study has presented us with some difficulties", explains one of the members of the research team. "The results obtained have shown that the main obstacle in the development of these materials is due to the high temperatures used in the ceramic manufacturing process, which can reach 1400º C, causing the biocide material to integrate into the ceramic glaze, making its activation difficult and reducing its effectiveness".

Therefore, this year, Bioceram intends to address the use of other alternative biocides to silver, in addition to the development of vitreous materials with bactericidal properties for use in water accumulation points such as siphons or taps, in order to incorporate them in environments especially sensitive to the spread of infections in places such as hospitals, health centres, centres for the elderly or schools, among others.
