Receiving of Ceramic Veneer with the Use of Unsorted Container Glass Breakage

Abstract

The results of studies on the production of ceramic material, which can be used for face veneer and pedestals are presented. This material was obtained on the basis of stiff clay with the addition of 30 % by weight of unsorted container glass breakage as a flux-hardening additive, which forms a vitreous phase during baking, and 2.5 % by weight of a fluxing agent that increases the amount of the vitreous phase and lowers the temperature of the liquid-phase sintering material. In turn, the vitreous phase acts as a binder in the bulk of the material due to the vitrification of the surface of the ceramic particles and their connection into a strong frame and creates the effect of self-glazing products. Studies have been conducted showing that the highest compressive strength and the lowest water absorption of the material being developed were obtained using boric acid as a fluxing agent and baking at a maximum burning temperature of 1050 °C.
