Functionalized enamel of ceramic tiles by sol gel technique (review)

The function of enamels for the ceramic tile industry has been a research topic for the past 15 years. Different researchers have focused their efforts on achieving surfaces with functional attributes that in-crease product value and provide solutions for the technological needs of our times. This article presents a review of the scientific literature dedicated to ob-taining functional surfaces by means of the sol-gel technique, which provides a means for deposition and formation of thin layers on traditional ceramic enamels in order to provide functional characteristics. The document presents: typically used alcoxidic solutions, the different deposition techniques emphasizing the experimental findings obtained by the authors, and a synthesis of the functional effects obtained by means of the technique.
