Infrared Spectra and Differential-Thermal Analysis of Ceramic Glaze Frits

Resumo

Measurements of the infrared spectra and the results of differential-thermal analysis of ceramic glaze frit are presented. The obtained data confirm the bi-phase nature of the studied frit and the presence in it of B³⁺ ions in triple and quaternary coordination. The presence of two phases in the studied frit — a stiff silicate frame and low-temperature borosilicate with moderate silica content— can lead to the formation of micro-liquations.
