Abstract:
Provided is a ceramic substrate. The ceramic substrate includes a core layer, made of zirconia toughened alumina; and surface layers, symmetrically located on an upper and a lower surfaces of the core layer, made of Al2O3. The core layer has a chemical composition of 0 wt %
Abstract:
A metal-ceramic composite includes a ceramic substrate and a metallic composite. A groove is formed in a surface of the ceramic substrate and the metallic composite is filled in the groove. The metallic composite includes a Zr based alloy-A composite. A includes at least one selected from a group consisting of W, Mo, Ni, Cr, stainless steel, WC, TiC, SiC, ZrC and ZrO 2 . Based on the total volume of the Zr based alloy-A composite, the content of A is about30%to about70%by volume.A method for preparing the metal-ceramic composite is also provided.
Abstract:
A sealing assembly, a method of preparing the sealing assembly and a battery are provided. The sealing assembly comprises a metal ring (1) having a mounting hole therein; a ceramic ring (2) having a connecting hole therein and disposed in the mounting hole; and a core column (3) disposed in the connecting hole, wherein at least one of an inner circumferential wall surface of the metal ring, an outer circumferential wall surface of the ceramic ring, an inner circumferential wall surface of the ceramic ring and an outer circumferential wall surface of the core column is configured as an inclined surface, and an inclination angle of the inclined surface relative to a vertical plane is about 1 degree to about 45 degrees.
