The invention concerns a process for the polishing of metallic dental prostheses, such as frames. In order to reproducibly obtain a defined surface roughness with no need for additional finishing, it is proposed for the dental prosthesis to be polished by means of plasma polishing.

Process for the polishing of metallic dental prostheses

The invention concerns a process for the production of a porous &#x3b2;-SiC-bearing ceramic molded body that includes an aluminum oxide layer at the surface of the pores and passages of the porous &#x3b2;-SiC-bearing ceramic molded body. The invention further concerns a porous &#x3b2;-SiC-bearing ceramic molded body which has pores of a mean pore size in the range of between 0.1 urn and 50 &#x3bc;m and an aluminum oxide layer at the surface of the open pores and passages.

Porous &#x3b2;-SiC-containing ceramic molded article comprising an aluminum oxide coating, and method for the production thereof

The invention relates to a process for the production of a molded porous ceramic article containing &#x3b2;-SiC, which process comprises the following steps: the preparation of a molded article containing silicon and carbon and the subsequent pyrolysis and siliconization of the article containing silicon and carbon to form SiC. The invention further relates to a molded porous ceramic article containing SiC which has been produced from a molded article containing silicon and carbon.
