Abstract
An oxynitride ceramic material includes a Ca7-8 Al15-15.5Si17-18O56-57N5-6 material and a Li6-4La3Zr1.4Ta0.6O12 material in an amount of 10 to 80 percent by weight (wt. %) based on a total weight of the oxynitride ceramic material. The oxynitride ceramic material is crystalline and includes phases including a lanthanum zirconium oxide (La2Zr2O7) phase, a lanthanum tantalum oxynitride (LaTaON2) phase, a lithium aluminate (LiAlO2) phase, a zirconium silicate (ZrSiO2) phase, and a lithium aluminosilicate (LiAlSi3O8) phase.
