    Abstract: 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.

    Abstract translation: 本发明涉及一种在其组成中含有高百分比的再循环硅酸铝的陶瓷制品的制造方法。 制造工艺包括形成网状网状物的基材的融合，该网状物填充有熔融的添加剂组合物。 基材提供了制品的尺寸稳定性和强度，而添加剂组合物赋予制品耐水性和韧性。 在本发明中，将具有工程化熔融温度的添加剂粉末添加到再循环的基材中。 将混合物加热直到回收的硅铝酸盐达到最佳定影温度。 继续加热直到添加剂开始熔化填充熔融硅铝酸盐颗粒之间的空隙。 然后将制品快速冷却以淬火而不破裂。 所得到的制品由于熔融氧化铝硅酸盐颗粒而具有高强度，并且由于熔融的添加剂组分填充了熔融硅酸铝颗粒之间的所有孔而导致低吸水率和高密度。
