This research demonstrates enhanced thermal properties in ceramics by using polymer waste in production, indicating a new manufacturing approach.
The paper presents results on the development of a facing ceramic material produced from the low-plasticity clay with the addition of boric acid and flat window glass cullet, which serve for liquid-phase sintering and achieving a surface self-glazing effect. Additionally, polymer waste, in particular, waste from consumed non-plasticized PVC products, was introduced as a combustible additive. The research results show how the basic properties of the produced ceramics depend on the polymer waste amount added to the batch, with boric acid and cullet included in quantities that provide the maximum possible strength and frost resistance. The optimal polymer waste amount was determined, enabling production of a material that meets the requirements for ceramic facing products and qualifies as conditionally effective in terms of thermal engineering characteristics. The resulting batch composition enables the joint utilization of polymer and glass waste, while simultaneously expanding the raw material base and product range for facing ceramics production.
