Abstract

The feasibility to substitute feldspar raw materials in a porcelain stoneware body with waste Cathode Ray Tube (CRT) glass was investigated. Various compositions, containing different percentages of feldspars and CRT glass, were compared. The densification process was studied by non-isothermal dilatometry and the degree of sintering was evaluated by pycnometric techniques. The structure and phase composition of the final ceramics were studied by SEM and XRD, respectively. The technological parameters and the mechanical properties were also measured and compared with a standard plant composition. It was highlighted that the addition of low viscous CRT glass gives a possibility to reduce the total amount of fluxes in the batch and to decrease the cost. Ceramics with characteristics, similar to the plan composition, were obtained by replacement of 5-14 % feldspars with 5-10 % CRT glass.
