Method of forming ceramic articles from recycled aluminosilicates
The present invention relates to a process of forming ceramic articles that contain a high percentage of recycled alumina silicate in their composition. The fabrication process includes a fusing of the base material forming a reticulated network that is in-filled with a melted additive composition. The base material gives the article dimensional stability and strength while the additive composition gives the article water resistance and toughness. In this invention, an additive powder with an engineered melting temperature is added to the recycled base material. The mixture is heated until the recycled aluminosilicate reaches the optimal fusing temperature. Heating is continued until the additive begins to melt filling the voids between the fused aluminosilicates particles. The article is then rapidly cooled to quench the fusing without cracking. The resulting article has high strength due to the fused alumina silicate particles and low water absorbance and high density due to the melted additive component filling all the pores between the fused alumina silicate particles.
