The invention relates to a process for metallizing ferrite ceramics, which comprises the following steps: arrangement of a. contact element composed of copper or a copper alloy on a surface of the ferrite ceramic, melting of the contact element at least in the region in which the contact element contacts the surface of the ferrite ceramic, and cooling of the contact element and the ferrite ceramic to below the melting point of copper or the copper alloy.

Disclosed herein is a method for applying metals to clay. More particularly, the present invention relates to applying malleable metals, such as silver, to clay, such that the metal attaches to the clay and as an added feature forms beads on the surface of the clay.

A ceramic device including a ceramic material, a patterned metal structure, and a surface activation material is provided. A surface of the ceramic material at least includes a first surface and a second surface that are not coplanar. The ceramic material has recesses on the surface thereof. The patterned metal structure is disposed on the first surface and the second surface. The surface activation material is disposed on a surface of the recesses and located at an interface between the ceramic material and the patterned metal structure.

Coated components, along with methods of their formation, are provided. The coated component may include a ceramic substrate having a Si-treated layer surrounding a ceramic core and an environmental barrier coating on the Si-treated layer of the ceramic substrate. The ceramic core may include silicon carbide, and the Si-treated layer may be pretreated to tailor its surface's properties for inhibiting or delaying the formation of carbon oxides to upon exposure of the Si-treated layer to oxygen.

A preparation method includes: pressing and forming a ceramic base material to obtain a green body of a ceramic plate; applying a ground glaze on the surface of the green body to cover the base color and defects of the green body; applying a cover glaze on the surface of the green body after applying the ground glaze, wherein the cover glaze contains 0.2 wt % to 0.7 wt % of coloring metal oxide to make the coloring bright; roller-printing patterns on the surface of the green body after applying the cover glaze to produce a flowing cloud effect; and drying the green body with the roller-printed patterns and firing in a kiln. The present invention uses roller printing to print the patterns of cloud effect on the surface of the cover glaze, which form a sharp contrast with the color of the cover glaze, producing a better visually distinct effect.
