Corrosion resistance of commercial glazes of floor tiles

Abstract

The main aim of this article was to develop new glaze receipts (NGRs) to build up the acid resistance (AR) of commercial glazes (CGs) used in floor tile production. The glaze is a vitrified material that melts the surface of the ceramic material. Improvements were made during and after the manufacture, based on the glaze samples of the CGs. NGRs were synthesized using different mineral compositions. AR, density, chemical, and physical properties of commercial and new synthesized glazes were determined using X-ray diffraction, scanning electron microscopy/energy-dispersive X-ray spectroscopy, Fourier transform infrared spectrometry, and water contact angle analysis methods. The AR of the obtained samples (standard and developed floor tiles) was examined by treating them with 3% HCl for 3 days. Results showed that synthesized glazes had higher AR than standard glazes (CGs). The NGRs also significantly improved the ceramic surface coating features of the new glazes.
