Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a method of making a composite ceramic material based on silicon nitride and beta-eucryptite.SOLUTION: There is provided a method of making a sintered composite ceramic material based on silicon nitride and beta-eucryptite. The method includes a step of preparing a first powdery mixture (101) composed of the powder of silicon nitride in a crystal form and the powder of first lithium aluminosilicate in a crystal form having a composition of (LiO)(AlO)(SiO). The combination of the molar fractions (x, y, z) in the composition of the lithium aluminosilicate is different from the combination of (1, 1, 2). |
